Description

The present invention relates to a data transmission program, a data comparison program, an information processing apparatus, a data transmission method, and a data comparison method.

For example, a business operator that provides a service to a user (hereinafter, also simply referred to as a business operator) constructs and operates a business system (hereinafter, also referred to as an information processing system) for providing the service. Then, when the business operator generates a program that constitutes a business system, the business operator performs various tests on the operation of the generated program.

Specifically, the program generated by the business operator includes, for example, a program for transmitting data between different information processing devices (physical machines) (hereinafter, also referred to as a data transmission program). Then, when the business operator generates a data transmission program, for example, there is no difference between the data before transmission and the data after transmission (data is not destroyed due to data transmission). ) Is performed (see, for example, Patent Documents 1 to 4).

JP-A-2007-207050 Japanese Unexamined Patent Publication No. 5-120164 International Publication No. 2008/11135 Japanese Unexamined Patent Publication No. 2004-355430

Here, the transmission test as described above is frequently performed, for example, with the revision of the data transmission program. Therefore, the storage area required for storing the test data used for performing the transmission test may become enormous.

Therefore, for example, when test data is generated in a memory, the business operator performs a transmission test in order from the generated test data without storing the generated test data in a storage area such as a disk device. This allows the operator to reduce the storage area required to perform the transmission test.

However, in this case, each transmission test is performed sequentially according to the generation of test data. Therefore, there may be a difference between the transmission order of test data and the arrival order of test data in the destination information processing device, depending on the state of the driver and the network operating in each information processing device. Therefore, the information processing device at the transmission destination cannot specify, for example, the data (hereinafter, also referred to as expected data) used for determining the normality of the test data received from the information processing device at the transmission source. , It may not be possible to judge the normality of the received test data.

Therefore, in one aspect, the present invention provides a data transmission program, a data comparison program, an information processing apparatus, a data transmission method, and a data comparison that enable the normality of the test data received at the destination of the test data to be determined. The purpose is to provide a method.

In one aspect of the embodiment, in a data transmission program that transmits a plurality of data, a plurality of data each having information associated with a position in the data is acquired, and the acquired plurality of data are analyzed. , Among the positions in the data, the position where the information does not overlap among any of the plurality of data is specified, and each of the acquired plurality of data and the information for identifying the specified position are transmitted. Let the computer perform the process.

According to one aspect, it is possible to determine the normality of the test data received at the destination of the test data.

[Specific example of transmission test in information processing system 10]
Next, a specific example of the transmission test in the information processing system 10 will be described.

When the test target unit 12 of the information processing device 1 receives a transmission test start instruction from the test control unit 11, it transmits a test data read instruction from the disk device 15 to the disk driver 13 ((1) in FIG. 1). ). Specifically, in this case, the test target unit 12 transmits an address on a memory (not shown) for writing the read test data to the disk driver 13 together with a test data read instruction.

Then, when the disk driver 13 receives the test data read instruction from the test target unit 12, the disk driver 13 does not read the test data from the disk device 15 but generates the test data ((2) in FIG. 1). Specifically, in this case, the disk driver 13 specifies, for example, a parameter for generating test data corresponding to the received read instruction among a plurality of parameters stored in advance in the storage area (not shown). , Generate test data from the specified parameters. After that, the disk driver 13 writes the generated test data to the address on the memory designated by the test target unit 12 ((3) in FIG. 2).

That is, in the example shown in FIG. 1 and the like, the disk device 15 does not store the test data corresponding to the read instruction transmitted by the test target unit 12. Therefore, when the disk driver 13 receives the test data read instruction from the test target unit 12, the disk driver 13 generates the test data corresponding to the received read instruction.

As a result, the business operator can carry out a transmission test between the information processing device 1 and the information processing device 2 without storing the test data to be transmitted to the information processing device 2 in the disk device 15 in advance. ..

Subsequently, the test target unit 12 transmits a test data transmission instruction to the network driver 14 ((4) in FIG. 3). Specifically, in this case, the test target unit 12 transmits the address on the memory in which the test data to be transmitted is stored to the network driver 14 together with the test data transmission instruction. Then, when the network driver 14 receives the test data transmission instruction from the test target unit 12, the network driver 14 transmits the test data corresponding to the received transmission instruction to the information processing device 2 ((5) in FIG. 3). Specifically, the network driver 14 transmits the test data stored in the address on the memory received from the test target unit 12 to the information processing device 2.

After that, the network driver 24 of the information processing device 2 writes the test data received from the information processing device 1 (network driver 14) to an address on a memory (not shown) designated in advance by the test target unit 22 (FIG. 3). (6)).

Subsequently, when the test data is written to the address on the memory designated in advance for the network driver 24, the test target unit 22 transmits an instruction to write the test data to the disk device 25 to the disk driver 23 (). (7) of FIG.

Then, when the disk driver 23 receives the test data writing instruction from the test target unit 22, the disk driver 23 does not write the test data to the disk device 25 and generates the test data ((8) in FIG. 4). Specifically, in this case, the disk driver 23 specifies, for example, the parameters used for generating the test data transmitted from the information processing apparatus 1 from the parameters stored in advance in the storage area (not shown). Generate test data from the specified parameters.

That is, when the disk driver 23 receives the test data write instruction from the test target unit 22, the disk driver 23 determines the normality of the test data received from the information processing device 1 instead of writing the test data to the disk device 25. Generate the expected data of.

After that, the disk driver 23 compares the test data (test data generated by the disk driver 13) transmitted from the information processing device 1 with the test data (expected data) generated by the disk driver 23 (FIG. 4). (9)).

As a result, when the contents of these data match, the disk driver 23 determines that the test data transmitted from the information processing device 1 is not destroyed by the transmission.

On the other hand, if the contents of these data do not match, the disk driver 23 determines that the test data transmitted from the information processing device 1 may have been destroyed by the transmission. Then, in this case, the test control unit 21 notifies the business operator of, for example, information indicating that an abnormality has occurred in the transmission test.

As a result, the business operator can carry out a transmission test between the information processing device 1 and the information processing device 2 without storing the expected data for the test data transmitted from the information processing device 1 in the disk device 25 in advance. Becomes possible.

However, in the above case, each transmission test is continuously performed according to the generation of test data in the information processing apparatus 1. Further, the order in which each transmission test is performed may be randomly determined by the test control unit 11 or the like. Therefore, there may be a difference between the transmission order of the test data and the arrival order of the test data in the information processing apparatus 2 depending on the state of the driver and the network operating in each information processing apparatus. Therefore, the information processing device 2 cannot specify the transmission test (test item of the transmission test) corresponding to the test data received from the information processing device 1, and cannot determine the normality of the received test data. In some cases.

Therefore, the disk driver 13 of the information processing device 1 in the present embodiment acquires a plurality of test data, each of which has information associated with a position in the data, analyzes the acquired plurality of data, and performs data. Among the positions within, specify the position where the information does not overlap between any of the plurality of data. Then, the test control unit 11 of the information processing apparatus 1 instructs the network driver 14 to transmit each of the plurality of data acquired by the disk driver 13 and the information identifying the position specified by the disk driver 13.

That is, the information processing device 1 identifies a position in which information having different contents (hereinafter, also referred to as unique information) is set in the plurality of test data before the plurality of test data is transmitted to the information processing device 2. Specify the information to be processed (hereinafter, also referred to as location information). Then, the information processing device 1 transmits not only the plurality of test data but also the position information specified based on the plurality of test data to the information processing device 2.

On the other hand, the disk driver 23 of the information processing device 2 in the present embodiment acquires information associated with a specific position in the test data received by the network driver 24. Then, the disk driver 23 refers to a storage unit that stores a plurality of expected data (a plurality of expected data generated in advance in the information processing apparatus 2), and acquires the expected data at a specific position among the plurality of expected data. Identify informed expected data. After that, the disk driver 23 compares the specified expected data with the test data received by the network driver 24, and outputs the comparison result.

That is, for example, before receiving the test data from the information processing device 1, the information processing device 2 acquires the position information corresponding to the plurality of test data specified by the information processing device 1 in advance. Here, in the information processing device 2, when each of the plurality of expected data stored in the storage unit is data generated from the same parameters as the plurality of test data used for specifying the position information acquired in advance. , It is possible to identify the expected data in which the information set at the position corresponding to the position information matches the test data transmitted from the information processing device 1 as the expected data generated by the same parameters as the test data. Is. Therefore, when the information processing device 2 receives the test data from the information processing device 1, the information processing device 2 should compare the expected data in which the information set at the position corresponding to the position information matches the test data with the received test data. Identify as expected data.

Therefore, when the information processing device 2 receives any of the plurality of test data from the information processing device 1, it refers to the position information corresponding to the plurality of test data and sets the position corresponding to the position information in the received test data. Identify the unique information that has been created. Then, the information processing apparatus 2 specifies the expected data in which the unique information is set at the position corresponding to the position information among the plurality of expected data generated in advance as the expected data to be compared with the received test data. After that, the information processing device 2 compares the test data received from the information processing device 1 with the specified expected data.

As a result, the information processing device 2 can specify the expected data that needs to be compared with the test data received from the information processing device 1. Therefore, in the information processing device 2, there is a difference between the transmission order of the test data performed by the test target unit 12 of the information processing device 1 and the arrival order of the test data in the disk driver 23 of the information processing device 2. Even in this case, it is possible to judge the normality of each test data.

Specifically, the test start unit 111 instructs the disk driver 13 to generate additional information before the transmission test is performed. Then, the test start unit 111 transmits the additional information generated by the disk driver 13 to the information processing device 2.

The test execution unit 112 of the test control unit 11 performs a process (hereinafter, also referred to as a test execution process) associated with the execution of the transmission test of the test target unit 12 among the data transmission processes. Specifically, the test execution unit 112 instructs the test target unit 12 to transmit the test data 144 stored in the information storage area 140.

The test end unit 113 of the test control unit 11 performs a process (hereinafter, also referred to as a test end process) associated with the end of the transmission test of the test target unit 12 among the data transmission processes. Specifically, the test end unit 113 compares the transmission test result information (not shown) generated by the information processing device 1 with the transmission test result information (not shown) generated by the information processing device 2. conduct.

The information receiving unit 121 of the disk driver 13 receives, for example, an instruction to generate additional information from the test starting unit 111. Further, the information receiving unit 121 receives, for example, a read instruction of the test data 144 from the test target unit 12.

The parameter generation unit 122 of the disk driver 13 generates the parameter 143 in response to, for example, the information receiving unit 121 receiving the additional information generation instruction and the test data 144 read instruction. Specifically, the parameter generation unit 122 generates the parameter 143 from, for example, the generation source information (not shown) stored in advance in the disk device 15. Then, the parameter generation unit 122 stores, for example, the generated parameter 143 in the information storage area 140.

Then, the test data generation unit 123 stores, for example, the generated test data 144 in the information storage area 140.

The position specifying unit 124 of the disk driver 13 analyzes a plurality of test data 144 generated by the test data generation unit 123, and among the positions in each test data 144, any test data of the plurality of test data 144 can be used. The position where the information does not overlap is specified, and the position information 145 indicating the specified position is generated. Then, the position specifying unit 124 stores, for example, the generated position information 145 in the information storage area 140.

The information transmission unit 125 of the disk driver 13 transmits the parameter 143 generated by the parameter generation unit 122 and the position information 145 (additional information) generated by the position identification unit 124 to the test start unit 111. After that, the test start unit 111 transmits the additional information transmitted by the information transmission unit 125 to the information processing device 2.

Further, the information transmission unit 125 tests the parameter 143 generated by the parameter generation unit 122, the position information 145 (additional information) generated by the position identification unit 124, and the test data 144 generated by the test data generation unit 123.

Specifically, in this case, the information transmission unit 125 transmits, for example, the test data 144 in which the additional information is partially overwritten to the test target unit 12. After that, the test target unit 12 transmits the additional information and the test data 144 (for example, the test data 144 overwritten with the additional information) transmitted by the information transmission unit 125 to the information processing device 2.

The information management unit 126 of the disk driver 13 updates each information stored in the information storage area 140. Specifically, the information management unit 126 generates or deletes pre-transfer information 146, transfer-in-transfer information 147, and transferred information 148, which are information indicating the transmission status of test data 144 to the information processing device 2, for example. The description of the maximum holding number information 141 and the holding number information 142 will be described later.

Further, the information receiving unit 221 receives, for example, a writing instruction of the test data 144 from the test target unit 22. Specifically, the write instruction of the test data 144 is an instruction to write the test data 144 received from the information processing device 1 by the test target unit 22 to the disk device 25. However, the disk driver 23 that has received the write instruction of the test data 144 can generate the expected data 241 and compare the test data 144 with the expected data 241 without writing the test data 144 to the disk device 25. conduct.

[First Embodiment]
Next, the first embodiment will be described. 8 and 9 are flowcharts illustrating the outline of the data transmission process according to the first embodiment.

[Data transmission processing in the first information processing device]
First, the outline of the data transmission process in the information processing apparatus 1 will be described. FIG. 8 is a flowchart illustrating an outline of data transmission processing in the information processing apparatus 1.

As shown in FIG. 8, the disk driver 13 of the information processing device 1 waits until the data transmission timing (NO in S1). The data transmission timing may be, for example, the timing at which the disk driver 13 receives a read instruction of the test data 144 from the test target unit 12.

Then, when the data transmission timing comes (YES in S1), the disk driver 13 acquires a plurality of test data 144, each of which has information associated with a position in the data (S2). Specifically, the disk driver 13 acquires the test data 144 by generating the test data 144 from the parameter 143 stored in the information storage area 140, for example.

Subsequently, the disk driver 13 analyzes the plurality of test data 144 acquired in the process of S2, and among the positions in each test data 144, the positions where the information does not overlap among any of the plurality of test data 144. Is specified (S3).

After that, the disk driver 13 transmits each of the plurality of test data 144 acquired in the process of S2 and information for identifying the position specified in the process of S3 (position information 145) (S4). Specifically, the disk driver 13 transmits the plurality of test data 144 acquired in the process of S2 and the position information 145 specified in the process of S3 to the test target unit 12. Then, the test target unit 12 transmits the plurality of test data 144 and the position information 145 transmitted from the disk driver 13 to the information processing device 2 via the network driver 14.

That is, the information processing device 1 identifies the position where information (unique information) having different contents is set in the plurality of test data 144 before transmitting the plurality of test data 144 to the information processing device 2. Identify 145. Then, the information processing device 1 transmits not only the plurality of test data 144 but also the position information 145 specified based on the plurality of test data 144 to the information processing device 2.

[Data transmission processing in the second information processing device]
Next, the outline of the data transmission process in the information processing device 2 will be described. FIG. 9 is a flowchart illustrating an outline of data transmission processing in the information processing apparatus 2.

As shown in FIG. 9, the disk driver 23 of the information processing device 2 waits until the test data 144 is received (NO in S11). Specifically, the disk driver 23 waits until the test target unit 22 receives the test data 144 from the information processing device 1.

Then, when the test data 144 is received (YES in S11), the disk driver 23 acquires the information associated with the specific position in the test data 144 received in the process of S11 (S12). Specifically, the disk driver 23 receives, for example, the position information 145 specified in advance from the plurality of test data 144 including the test data 144 received in the process of S11 by the test control unit 21 or the test target unit 22. If so, the position information 145 may be used as a specific position.

Subsequently, the disk driver 23 refers to the information storage area 240 that stores the plurality of expected data 241 and has the expected data 241 having the information acquired in the process of S12 at a specific position among the plurality of expected data 241. Is specified (S13).

Further, the disk driver 23 compares the expected data 241 specified in the process of S13 with the test data 144 received in the process of S11 (S14). After that, the disk driver 23 outputs the comparison result performed in the process of S14 (S15).

That is, for example, the information processing device 2 receives the position information 145 specified by the information processing device 1 (position information 145 specified from the plurality of test data 144) before receiving the test data 144 from the information processing device 1. Obtain in advance. Here, when each of the plurality of expected data 241 stored in the information storage area 240 is data generated from the same parameter 143 as the plurality of test data 144 used for specifying the position information 145 acquired in advance. The expected data 241 whose information set at the position corresponding to the position information 145 matches the test data 144 transmitted from the information processing apparatus 1 is the expected data 241 generated by the same parameter 143 as the test data 144. It is possible to specify. Therefore, when the information processing device 2 receives the test data 144 from the information processing device 1, the information processing device 2 receives the expected data 241 in which the information set at the position corresponding to the position information 145 matches the test data 144. It is specified as expected data 241 to be compared with 144.

Therefore, when the information processing device 2 receives any one of the plurality of test data 144 from the information processing device 1, it refers to the position information 145 corresponding to the plurality of test data 144, and in the received test data 144, the position information 145 is used. Identify the unique information set at the corresponding position. Then, the information processing apparatus 2 should compare the expected data 241 in which the unique information is set at the position corresponding to the position information 145 among the plurality of expected data 241 generated in advance with the received test data 144. Specified as 241. After that, the information processing device 2 compares the test data 144 received from the information processing device 1 with the specified expected data 241.

As a result, the information processing device 2 can specify the expected data 241 that needs to be compared with the test data 144 received from the information processing device 1. Therefore, in the information processing device 2, there is a difference between the transmission order of the test data 144 performed by the test target unit 12 of the information processing device 1 and the arrival order of the test data 144 in the disk driver 23 of the information processing device 2. Even if this is the case, it is possible to determine the normality of each test data 144.

FIG. 10 is a flowchart illustrating the details of the test start process in the test control unit 11. Hereinafter, the identification information of the information processing device 2 which is the transmission destination of the test data 144 and the like, the planned number of times the transmission test is performed, the maximum multiplicity which is the number at which the test data 144 and the like can be transmitted at the same time, and additional information. Each information (not shown) including the maximum overwrite data length which is the maximum amount of data and the initial value of the position information 145 will be described as being stored in advance in the information storage area 140 by the business operator.

As shown in FIG. 10, the test start unit 111 waits until the test start timing (NO in S21). The test start timing may be, for example, the timing at which the operator inputs to the test control unit 11 to start the transmission test.

Then, when the test start timing is reached (YES in S21), the test start unit 111 transmits an additional information generation instruction to the disk driver 13 (S22). Specifically, the test start unit 111 includes, for example, among the information stored in the information storage area 140, the identification information of the information processing device 2, the planned number of transmission test executions, the maximum multiplicity, the maximum overwrite data length, and the maximum overwrite data length. Each information including the initial value of the position information 145 is acquired, and the acquired information is transmitted to the disk driver 13 together with an instruction to generate additional information.

After that, the test start unit 111 waits until the additional information is generated in the disk driver 13 (NO in S23). Specifically, the test start unit 111 refers to the number indicated by the retained number information 142 stored in the information storage area 140 (hereinafter, also referred to as the retained number), and the additional information of the number indicated by the retained number information 142 is generated. Wait until The retained number information 142 may be, for example, information indicating a number twice the maximum multiplicity.

Further, hereinafter, in addition to the parameter 143 and the position information 145, the number of the position information 145 and the data length of the parameter 143 will be described as being included in the additional information.

Then, when the additional information is generated (YES in S23), the test start unit 111 transmits the additional information generated by the disk driver 13 to the information processing device 2 (S24).

Specifically, the test start unit 111 includes, for example, additional information generated by the disk driver 13 (additional information of the number indicated by the retention number information 142), the maximum overwrite data length, and data including the retention number (hereinafter, notification). (Also called data) is generated and transmitted to the information processing device 2.

Next, the details of the test start process in the disk driver 13 of the information processing device 1 will be described. FIG. 11 is a flowchart illustrating the details of the test start process in the disk driver 13.

The information receiving unit 121 waits until it receives an additional information generation instruction from the test control unit 11 (NO in S31).

Then, when the additional information generation instruction is received (YES in S31), the parameter generation unit 122 refers to the number indicated by the maximum retained number information 141 stored in the information storage area 140 (hereinafter, also referred to as the maximum retained number). Then, the parameter 143 is generated so that the number of the generated parameters 143 in the information storage area 140 becomes the maximum number to be held (S32). After that, the parameter generation unit 122 stores the generated parameter 143 in the information storage area 140. The number indicated by the maximum retention number information 141 (maximum retention number) may be, for example, a number obtained by subtracting 1 from a number four times the maximum multiplicity. Hereinafter, description will be made assuming that the maximum retained number information 141 is information indicating a number obtained by subtracting 1 from a number four times the maximum multiplicity.

Subsequently, the test data generation unit 123 generates a packet (leading packet) of the test data 144 using the parameter 143 generated in the process of S32 (S33). After that, the test data generation unit 123 stores the generated packet of the test data 144 in the information storage area 140.

That is, the parameter generation unit 122 generates the parameter 143 so that the number of the parameter 143 stored in the information storage area 140 and the number of the first packets of the test data 144 become the maximum number to be held.

Next, the position specifying unit 124 refers to the retained number information 142 stored in the information storage area 140, and among the test data 144 generated in the process of S33, for each of the retained number test data 144 having the earliest transmission order. , The position (position information 145) where the information does not overlap between the test data 144 of the retained number of the test data 144 whose transmission order is continuous is specified from each test data 144 (S34). Then, the position specifying unit 124 refers to the retained number information 142 stored in the information storage area 140, and among the test data 144 generated in the process of S33, for each of the retained number test data 144 having the earliest transmission order, The position information 145 specified in the process of S34 is associated with each data of the number of retained test data 144 whose transmission order is continuous from each test data 144 (S35).

Specifically, for example, when the maximum multiplicity is 2, the number of holdings is 4, and the maximum number of holdings is 7. Therefore, in this case, the position specifying unit 124, for example, from the test data 144 having the earliest transmission order to the test data 144 having the fourth earliest transmission order among the seven test data 144 stored in the information storage area 140. Each of the four test data 144 from the test data 144 having the earliest transmission order to the test data 144 having the fourth earliest transmission order is located at a position where the information does not overlap among any of the four test data 144. Correspond to. Further, the position specifying unit 124 is, for example, from the test data 144 having the second earliest transmission order to the test data 144 having the fifth earliest transmission order among the seven test data 144 stored in the information storage area 140. The position where the information does not overlap among any of the four test data 144 is the position of the four test data 144 from the test data 144 having the second earliest transmission order to the test data 144 having the fifth earliest transmission order. Correspond to each.

Further, in this case, the position specifying unit 124, for example, has the test data 144 having the third earliest transmission order among the seven test data 144 stored in the information storage area 140, and the test data having the sixth earliest transmission order. Four tests from the test data 144, which has the third earliest transmission order, to the test data 144, which has the sixth earliest transmission order, at positions where information does not overlap among any of the four test data 144 up to 144. Corresponds to each of the data 144. After that, the position specifying unit 124, for example, out of the seven test data 144 stored in the information storage area 140, from the test data 144 having the fourth earliest transmission order to the test data 144 having the seventh earliest transmission order. The position where the information does not overlap among any of the four test data 144 is the position of the four test data 144 from the test data 144 having the fourth earliest transmission order to the test data 144 having the seventh earliest transmission order. Correspond to each.

In the process of S34, the position specifying unit 124 may repeat the comparison of the information included in each test data 144 until, for example, the position where the unique information is set is specified.

Specifically, the position specifying unit 124 sets, for example, the position indicated by the initial value of the position information 145 transmitted from the test start unit 111 as the position where it is first determined whether or not the unique information is set. Then, the position specifying unit 124 sets the position for determining whether or not the unique information is set, for example, by a predetermined data length from the position indicated by the initial value of the position information 145 to the position behind the test data 144. The position where the unique information is set may be specified while changing. As a result, when the position where the unique information is set is not specified, the position specifying unit 124 indicates, for example, the position where it is determined whether or not the unique information is set by the initial value of the position information 145. The position where the unique information is set may be further specified while changing the position different from the position to the rear position in the test data 144 by a predetermined data length.

Further, in the transfer information 147 shown in FIG. 28 (B), an address in the information storage area 140 in which the parameter 143 used for generating the packet of the test data 144 being transferred to the information processing device 2 is stored is set. It has a "parameter address" to be processed as an item. Further, in the transfer information 147 shown in FIG. 28B, among the packets of the test data 144 being transferred to the information processing device 2, the packet to be transmitted next to the information processing device 2 is stored. Of the "test data address" in which the address in the information storage area 140 is set and the test data 144 packets being transferred to the information processing device 2, the packet to be transmitted next to the information processing device 2 It has a "packet number" in which a packet number is set as an item. Further, the transfer information 147 shown in FIG. 28B has a “total data length” in which the total data length of the test data 144 being transferred to the information processing device 2 is set, and the information processing device 2 Among the total data lengths of the test data 144 being transferred, the item includes the "remaining data length" in which the data length of the data that has not yet been transmitted to the information processing apparatus 2 is set. Further, the transfer information 147 shown in FIG. 28B is the timing at which the information processing device 2 is notified of additional information including the parameter 143 used for generating the test data 144 being transferred to the information processing device 2. Has "notification timing" as an item to be set.

Specifically, in the in-transit information 147 shown in FIG. 28 (B), "address A5" is set as the "READ address" for the information whose "item number" is "1", and "parameter address" is set to "1". "Address A1" is set, and "Address A2" is set as the "test data address". Further, in the in-transit information 147 shown in FIG. 28 (B), "1" is set as the "packet number" for the information whose "item number" is "1", and "1048576" is set as the "total data length". Bytes) ”is set,“ 1047552 (bytes) ”is set as the“ remaining data length ”, and“ test start processing ”is set as the“ notification timing ”.

As for the information set in the "remaining data length" in the transfer information 147 shown in FIG. 28 (B), for example, a packet of test data 144 was generated in the process of S91 described later, and the packet size was determined. It may be updated later. Further, in the in-transit information 147 shown in FIG. 28 (B), the information set in the "packet number" is, for example, one in which "1" is added in the processing of S83 or S91 described later. good. Further, in the transfer information 147 shown in FIG. 28 (B), the information set in the "test data address" is, for example, the test data 144 generated by generating a packet of test data 144 in the process of S91 described later. May be updated as the data is stored in the information storage area 140.

On the other hand, in the pre-transfer information 146 shown in FIG. 28 (A), the information in which the “item number” is “1” is deleted from the pre-transfer information 146 described in FIG. 26 (A). That is, in the pre-transfer information 146 shown in FIG. 28 (A), among the pre-transfer information 146 described in FIG. 26 (A), the “parameter address” and the “test” of the in-transfer information 147 described in FIG. 28 (B). The same information as the information set in the "data address" is deleted from the information set in the "parameter address" and the "test data address" (information in which the "item number" is "1").

Returning to FIG. 16, when the read instruction is not the read instruction of the first packet of the test data 144 in the process of S82, the information management unit 126 refers to the transfer information 147 stored in the information storage area 140 and processes the S81. The parameter address associated with the READ address included in the read instruction received in is specified (S83). Specifically, the information management unit 126 refers to, for example, the transfer information 147 described with reference to FIG. 28 (B), and the READ address included in the read instruction received in the process of S81 is set to the "READ address". Specify the information set in the "parameter address" of the information. Then, as shown in FIG. 17, the test data generation unit 123 generates a packet of test data 144 from the parameter 143 stored in the parameter address specified in the process of S83 (S91).

That is, when the read instruction received in the process of S81 is not the read instruction of the first packet of the test data 144, the READ address included in the read instruction is set in the transfer information 147 as described later. Therefore, the information management unit 126 refers to the transfer information 147 and specifies the information corresponding to the READ address included in the read instruction received in the process of S81, so that the information in transfer 147 can be processed in S81. It becomes possible to specify the information corresponding to the received read instruction.

Subsequently, the information management unit 126 determines whether or not the packet generated in the process of S91 is the final packet (S92).

Specifically, the information management unit 126 determines whether or not the packet generated by the process of S91 is smaller than the packet size, and thus determines whether or not the packet generated by the process of S91 is the final packet. It may be the one that makes a judgment. Further, the information management unit 126 determines whether or not the packet is the final packet by, for example, determining whether or not the packet generated in the process of S91 has reached EOF (End Of File). It may be a thing.

As a result, when it is determined that it is not the final packet (NO in S92), the information management unit 126 includes the READ address included in the read instruction received in the process of S81 among the in-transit information 147 stored in the information storage area 140. Updates the information set in the "READ address" of the information set in the "READ address" (S93). Specifically, the information management unit 126 sets an address obtained by adding the packet size to the address currently set in the "READ address" to the "READ address" as a new READ address.

Then, the disk driver 13 ends the test execution process. That is, the disk driver waits until it receives a read instruction for the next test data 144 from the test target unit 12 (NO in S81).

On the other hand, in the processing of S92, when it is determined that the packet generated in the processing of S91 is the final packet (YES in S92), the information management unit 126 corresponds to the READ address included in the read instruction received in the processing of S81. It is determined whether or not additional information can be set in the final packet of the test data 144 (hereinafter, also simply referred to as the final packet) (S94).

That is, for example, the information management unit 126 sets the READ address included in the read instruction received in the process of S81 to the "READ address" of the information being transferred 147 stored in the information storage area 140. When the information set in "remaining data length" is larger than the maximum overwrite data length (not shown) stored in the information storage area 140, it is determined that additional information can be set in the final packet.

As a result, when it is determined that the additional information can be set (YES in S94), the parameter generation unit 122 generates one new parameter 143 (S95). Then, the parameter generation unit 122 stores the generated parameter 143 in the information storage area 140.

Further, the test data generation unit 123 generates a packet (leading packet) of the test data 144 by using the parameter 143 generated in the process of S95 (S96). Then, the test data generation unit 123 stores the generated packet of the test data 144 in the information storage area 140.

Subsequently, as shown in FIG. 18, the position specifying unit 124 transmits the generated parameters 143 (parameters 143 stored in the information storage area 140) among the parameters 143 that have not been transmitted to the information processing apparatus 2. Identify the earliest parameter 143. Then, the position specifying unit 124 identifies and specifies a position where the information does not overlap between the test data 144 of the test data 144 generated from the specified parameter 143 and the test data 144 of the holding number having a continuous transmission order. The position information 145 indicating the position is generated (S101). Then, the position specifying unit 124 associates the position information 145 generated in the process of S101 with each of the test data 144 of the retained number in which the transmission order is continuous from the test data 144 generated from the parameter 143 specified in the process of S101. (S102). Further, the position specifying unit 124 stores the position information 145 associated with each of the test data 144 in the information storage area 140.

After that, the test data generation unit 123 includes additional information including the parameter 143 generated in the process of S95 and the position information 145 generated in the process of S101 at a predetermined position of the packet of the test data 144 generated in the process of S91. Is set (S103). Specifically, the test data generation unit 123 sets the additional information by overwriting the additional information with respect to the last position of the packet of the test data 144 generated in the process of S91, for example.

Further, the information management unit 126 generates pre-transfer information 146 from the additional information or the like set in the process of S103 (S104).

As a result, as will be described later, when the disk driver 13 transmits the test data 144 to the information processing device 2, the disk driver 13 also includes additional information corresponding to the test data 144 transmitted after the test data 144. It becomes possible to send.

Then, the information management unit 126 determines whether or not it is possible to set further additional information in the final packet of the test data 144 corresponding to the READ address included in the read instruction received in the process of S81. It is determined whether or not the number of the set additional information has not reached the retained number (S105).

That is, for example, the information management unit 126 sets the READ address included in the read instruction received in the process of S81 to the "READ address" of the information being transferred 147 stored in the information storage area 140. When the information set in "remaining data length" is twice or more the maximum overwrite data length (not shown) stored in the information storage area 140, it is determined that additional information can be set in the final packet.

As a result, when it is possible to set further additional information and it is determined that the number of the set additional information has not reached the retained number (YES in S105), the parameter generation unit 122 and the like may perform. The processing after S95 is performed again. That is, in this case, the disk driver 13 further sets additional information for the final packet of the test data 144 corresponding to the READ address included in the read instruction received in the process of S81.

On the other hand, when it is determined that the additional information cannot be set, or the number of the already set additional information has reached the retained number (NO in S105), or when it is determined that the additional information cannot be set (NO). NO) of S94, as shown in FIG. 19, the information management unit 126 generates the transferred information 148 from the parameter address of the parameter 143 used for generating the test data 144 generated in the process of S91 (S111). .. Then, the information management unit 126 deletes the information including the parameter address of the parameter 143 used for generating the test data 144 generated in the process of S91 from the information being transferred 147 (S112). Hereinafter, specific examples of the in-transit information 147 and the transferred information 148 will be described.

[Specific example of pre-transfer information, in-transfer information, and transferred information in the first information processing apparatus (3)]
FIG. 29 is a diagram illustrating specific examples of pre-transfer information 146, in-transfer information 147, and transferred information 148. Specifically, FIG. 29A is a diagram illustrating a specific example of pre-transfer information 146 including information generated in the process of S104, and FIG. 29B is a diagram in which the information is deleted in the process of S112. FIG. 29 (C) is a diagram for explaining a specific example of the transferred information 147, and FIG. 29 (C) is a diagram for explaining a specific example of the transferred information 148 for which information was generated in the process of S111.

In the pre-transfer information 146 shown in FIG. 29 (A), information in which the “item number” is “8” is added to the pre-transfer information 146 described in FIG. 28 (A). Then, "0x20", which is the position information 145 specified in the processes of S101 and S102, is set in the "unique address" of the information whose "item number" is "5" to "8", respectively.

Further, in the process of S113 described later, the parameter 143 stored in the "address E1" is transmitted together with the test data 144 stored in the "address A1", for example. Therefore, in the pre-transfer information 146 shown in FIG. 29 (A), the "notification timing" of the information whose "item number" is "5" indicates the "test" indicating the test data 144 stored in the "address A1". "Data A" is set.

Further, the transferred information 148 shown in FIG. 29C has a “item number” for identifying each information included in the transferred information 148 and a parameter 143 used for generating the test data 144 generated in the process of S91. It has a "parameter address" in which the address in the stored information storage area 140 is set as an item. Further, the transferred information 148 shown in FIG. 29C includes a "notification timing" in which the timing at which the additional information including the parameter 143 used for generating the test data 144 is notified to the information processing apparatus 2 is set. It has an item of "total data length" in which the total data length of the test data 144 is set.

Specifically, in the transferred information 148 shown in FIG. 29 (C), "address A1" is set as the "parameter address" for the information whose "item number" is "1", and "notification timing" is set to "1". "Start processing" is set, and "1048576" is set as the "total data length".

On the other hand, in the in-transit information 147 shown in FIG. 29 (B), the information in which the "item number" is "1" is deleted from the in-transfer information 147 described in FIG. 28 (B). That is, in the in-transit information 147 shown in FIG. 29 (B), the information corresponding to the information in which the “item number” of the transferred information 148 described in FIG. 29 (C) is “1” is deleted.

Returning to FIG. 19, the information transmission unit 125 transmits the test data 144 generated in the process of S91 or the test data 144 in which the additional information is set in the process of S103 to the test target unit 12 (S113).

Then, the disk driver 13 ends the test execution process. That is, the disk driver waits until it receives a read instruction for the next test data 144 from the test target unit 12 (NO in S81).

As a result, when the test data 144 is transmitted to the information processing device 2, the disk driver 13 can perform additional information corresponding to the test data 144 after the test data 144.

[Details of test execution processing in the disk driver of the second information processing device]
Next, the details of the test execution process in the disk driver 23 of the information processing device 2 will be described. 20 to 23 are flowcharts illustrating the details of the test execution process in the disk driver 23.

As shown in FIG. 20, the information receiving unit 221 waits until it receives a write instruction of the test data 144 from the test target unit 22 (NO in S121). Specifically, the information receiving unit 221 waits until the test target unit 22 that has received the test data 144 from the information processing device 1 transmits a write instruction of the test data 144 to the disk driver 23.

Then, when the write instruction of the test data 144 is received (YES in S121), the information receiving unit 221 determines whether or not the received write instruction is a write instruction of the first packet of the test data 144 (S122). Specifically, the information receiving unit 221 refers to the in-transit information 243 (details will be described later) stored in the information storage area 240, and sets the WRITE address included in the write instruction of the test data 144 received in the process of S121. By determining whether or not the information to be set in the "WRITE address" exists, it is determined whether or not the write instruction received in the process of S121 is the write instruction of the first packet of the test data 144. good.

As a result, when the write instruction is the write instruction of the first packet of the test data 144 (YES in S122), the information management unit 226 acquires the common position information 244 stored in the information storage area 240 (S123).

Then, in the information management unit 226, among the packets of the expected data 241 that have been generated, the information set at the position indicated by the common position information 244 acquired in the process of S123 corresponds to the write instruction received in the process of S121. The packet of the expected data 241 that matches the packet of the test data 144 is specified (S124). Specifically, the information management unit 226 is set to the position indicated by the common position information 244 from the expected data 241 stored in the information storage area 240 and including the information in the pre-transfer information 242. Identify a packet of expected data 241 whose information matches the packet of test data 144 corresponding to the write instruction.

That is, the common position information 244 is information indicating the position of unique information in the expected data 241 stored in the information storage area 240 and including the information in the in-transit information 243. Therefore, the information management unit 226 receives from the packet of the generated expected data 241 in the process of S121 by comparing the information set at the position indicated by the common position information 244 in each of the generated expected data 241. It becomes possible to specify a packet to be compared with the packet of the test data 144 included in the written instruction.

Subsequently, the information management unit 226 generates the transfer information 243 from the WRITE address and the like included in the write instruction received in the process of S121 (S125). Then, the information management unit 226 stores the generated transfer information 243 in the information storage area 240. Further, the information management unit 226 deletes the information including the parameter address included in the in-transfer information 243 generated in the process of S125 from the pre-transfer information 242 stored in the information storage area 240 (S126).

[Specific example of pre-transfer information and in-transfer information in the second information processing apparatus (2)]
FIG. 30 is a diagram illustrating specific examples of pre-transfer information 242 and in-transfer information 243. Specifically, FIG. 30A is a diagram illustrating a specific example of pre-transfer information 242 after the information is deleted in the process of S126, and FIG. 30B is a diagram generated in the process of S125. It is a figure explaining the specific example of the transfer information 243 including information.

The transfer information 243 shown in FIG. 30B is set by a "item number" for identifying each information included in the transfer information 243 and a WRITE address included in the write instruction of the test data 144 received in the process of S121. It has an item to be "WRITE address". Further, the in-transfer information 243 shown in FIG. 30B has, for example, a "parameter address" in which an address in the information storage area 240 in which the parameter 143 used for generating the expected data 241 is stored is set as an item. .. Further, the transfer information 243 shown in FIG. 30B includes a “packet number” in which the packet number of the next transmitted packet among the packets of the test data 144 being transferred from the information processing device 1 is set. Among the packets of the test data 144 being transferred from the information processing apparatus 1, the item includes an "expected data address" in which the address in the information storage area 240 in which the next transmitted packet is stored is set.

Specifically, in the in-transit information 243 shown in FIG. 30 (B), "address A6" is set as the "WRITE address" for the information whose "item number" is "1", and "parameter address" is set to "1". Address A1 ”is set. Further, in the in-transit information 243 shown in FIG. 30 (B), "1" is set as the "packet number" for the information whose "item number" is "1", and "address A4" is set as the "expected data address". Is set.

In the in-transit information 243 shown in FIG. 30 (B), the information set in the "packet number" is determined, for example, that the write instruction received in the process of S121 is not the write instruction of the first packet of the test data 144. In that case, "1" may be added. Further, in the transfer information 243 shown in FIG. 30 (B), the information set in the "WRITE address" sets the packet size to the address currently set in the "WRITE address" in the process of S135 described later, for example. The added address may be set as a "WRITE address" as a new WRITE address. Further, in the in-transit information 243 shown in FIG. 30 (B), the information set in the "expected data address" is, for example, a packet of expected data 241 generated in the process of S135 described later, and the generated packet is information. It may be updated as it is stored in the storage area 240.

On the other hand, in the pre-transfer information 242 shown in FIG. 30 (A), the information whose "item number" is "1" is deleted from the pre-transfer information 242 described with reference to FIG. 27. That is, in the pre-transfer information 242 shown in FIG. 30 (A), the information corresponding to the information in which the “item number” of the in-transfer information 147 described in FIG. 30 (B) is “1” is deleted.

Returning to FIG. 21, the information management unit 226 specifies the packet of the expected data 241 specified in the process of S124 as correct answer data (S131).

Then, the information management unit 226 determines whether or not the packet included in the write instruction received in the process of S121 is the final packet (S132).

Then, when it is determined that the packet included in the write instruction received in the process of S121 is not the final packet (NO in S132), the data comparison unit 224 sets the correct answer data (packet) specified in the process of S131 or S136 and S121. It is compared with the packet of the test data 144 included in the write instruction received in the process of (S133).

As a result, when it is determined that the contents of the correct answer data and the test data 144 match (YES in S134), the expected data generation unit 222 generates the packet next to the packet specified as the correct answer data in the process of S131 (S135). .. Then, the expected data generation unit 222 stores the generated packet in the information storage area 240. Further, the information management unit 226 identifies the packet generated in the process of S135 as correct answer data (S136).

Then, the disk driver 23 ends the test execution process. That is, the disk driver 23 waits until it receives a write instruction for the next test data 144 from the test target unit 22 (NO in S121).

Further, in the process of S132, when it is determined that the packet included in the write instruction received in the process of S121 is the final packet (YES in S132), the data comparison unit 224 determines S131 or S136 as shown in FIG. The actual data of the correct answer data (packets) specified in the process of S121 is compared with the actual data of the packets of the test data 144 corresponding to the write instruction received in the process of S121 (S141).

That is, there is a possibility that additional information is set in the final packet of the test data 144. Therefore, for example, when comparing the correct answer data and the test data 144, the data comparison unit 224 compares the data (actual data) other than the additional information.

Then, when the contents of the correct answer data and the test data match (YES in S142), the information management unit 226 sets the packet of the test data 144 included in the write instruction received in the process of S121 as shown in FIG. 23. It is determined whether or not the additional information is set (S151).

As a result, when it is determined that the additional information is set (YES in S151), the information management unit 226 generates the pre-transfer information 242 from the parameter address or the like included in the additional information existing in the process of S151 (YES in S151). S152). Then, the expected data generation unit 222 generates a packet of the expected data 241 from the parameter 143 included in the additional information existing in the process of S151 (S153).

Further, the common position specifying unit 223 identifies common information in the generated expected data 241 and generates the specified information as common position information 244 (S154). Specifically, the common position specifying unit 223 identifies common information in the expected data 241 stored in the information storage area 240 and including the information in the pre-transfer information 242. Then, the information management unit 226 deletes the information including the WRITE address and the like included in the write instruction received in the process of S121 out of the transfer information 243 stored in the information storage area 240 (S155). Hereinafter, specific examples of the pre-transfer information 242 and the in-transfer information 243 will be described.

[Specific example of pre-transfer information and in-transfer information in the second information processing apparatus (2)]
FIG. 31 is a diagram illustrating specific examples of pre-transfer information 242 and in-transfer information 243. Specifically, FIG. 31 (A) is a diagram illustrating a specific example of pre-transfer information 242 in which information was generated in the process of S152, and FIG. 31 (B) is a diagram in which the information was deleted in the process of S155. It is a figure explaining the specific example of the transfer information 243.

In the pre-transfer information 242 shown in FIG. 31 (A), information in which the “item number” is “5” is added to the pre-transfer information 242 described in FIG. 30 (A). Further, in the transfer information 243 shown in FIG. 31 (B), the information in which the “item number” is “1” is deleted from the transfer information 147 described in FIG. 31 (B).

Returning to FIG. 22, when the correct answer data and the contents of the test data 144 do not match in the processing of S142 (NO in S142), or when the correct answer data and the contents of the test data 144 do not match in the processing of S134 (NO). NO) of S134, the information management unit 226 outputs an error to, for example, a business terminal (not shown) (S143).

Then, in this case, the information management unit 226 acquires information regarding the comparison result (S144). The information management unit 226 may acquire information on the comparison result even when the contents match in the processing of S134 or S142.

As a result, the disk driver 23 can identify the packet of the expected data 241 to be compared with the packet of the test data 144 received from the information processing device 1, and can determine the normality of the packet of the received test data 144. become.

[Details of test end processing in the second control unit of the second information processing device]
Next, the details of the test end processing in the test control unit 21 of the information processing apparatus 2 will be described. FIG. 24 is a flowchart illustrating the details of the test end process in the test control unit 21.

As shown in FIG. 24, the test end unit 212 waits until the result comparison timing is reached (NO in S161). The result comparison timing may be, for example, the timing at which the test execution process is completed.

Then, when the result comparison timing is reached (YES in S161), the test end unit 212 transmits information regarding the comparison result acquired in the process of S144 to the test control unit 11 of the first information processing apparatus 1 (YES in S161). S162).

[Details of test end processing in the first control unit of the first information processing device]
Next, the details of the test end processing in the test control unit 11 of the information processing apparatus 1 will be described. FIG. 25 is a flowchart illustrating the details of the test end process in the test control unit 11.

As shown in FIG. 25, the test end unit 113 waits until it receives the information regarding the comparison result transmitted from the information processing device 2 (NO in S171). Then, when the information regarding the comparison result is received (YES in S171), the test end unit 113 compares the information regarding the received comparison result with the information regarding the transmission result acquired in the process of S74 (S172). In this case, the test end unit 113 adds, for example, information related to the transmission result acquired in the process of S74 to the information included in the transfer information 147 and the transfer information 148 stored in the information storage area 140. It may be compared with the information regarding the comparison result received in the process of S171.

Specifically, the test end unit 113 includes, for example, whether the information regarding the comparison result received in the process of S171 includes information indicating that there is a transmission test whose contents do not match in the process of S134 or S142. Judge whether or not. Then, when it is determined that there is a transmission test whose contents do not match (hereinafter, also referred to as a result abnormality test), the test end unit 113 is used to generate a packet of the expected data 241 used in the result abnormality test. The parameter 143 is compared with the parameter 143 used to generate the packet of the test data 144 corresponding to the expected data 241.

As a result, when the contents of the parameter 143 do not match, the test end unit 113 determines, for example, that there is an abnormality in the transmission test in which the transmission of the parameter 143 is performed. On the other hand, when the contents of the parameters 143 match, the test end unit 113 generates test data 144 from the parameters 143 having the same contents, and transmits the test data 144 from the information processing device 1 to the information processing device 2 in the transmission test. Compare with the test data 144. Then, when the contents of the test data 144 do not match, the test end unit 113 determines, for example, that there is an abnormality in the transmission test in which the test data 144 is transmitted.

Returning to FIG. 25, the test end unit 113 outputs, for example, the comparison result in the process of S172 on the operator terminal (not shown) (S173).

As a result, the test end unit 113 can verify the normality of the transmission test based on the information acquired by the information processing device 1 and the information processing device 2.

[Specific example of test transmission processing]
Next, a specific example of the test transmission process will be described. 32 to 41 are views for explaining a specific example of the test transmission process. Hereinafter, it is assumed that the data DT 11 in the information processing device 1 indicates each data included in the pre-transfer information 146, and the data DT 12 in the information processing device 1 indicates each data included in the in-transfer information 147. I do. Further, hereinafter, it is assumed that the data DT 21 in the information processing device 2 indicates each data included in the pre-transfer information 242, and the data DT 22 in the information processing device 2 indicates each data included in the in-transfer information 243. I do. Further, hereinafter, the packet numbers of each test data 144 and expected data 241 are shown in parentheses.

As shown in FIG. 32, the information processing apparatus 1 generates parameter G from parameter A, which is seven parameters 143 corresponding to the maximum number of holdings, as data included in the data DT 11 (S32). Then, the information processing apparatus 1 generates test data G (1) from test data A (1), which is test data 144 corresponding to each of the generated parameters 143, as data included in the data DT 11 (S33). .. Further, the information processing apparatus 1 includes test data A (1) to test data D (1), test data B (1) to test data E (1), test data C (1) to test data F (1), and the like. Positions A to D, which are position information 145 indicating unique information in each of the test data D (1) to the test data G (1), are generated as data included in the data DT11 (S34, S35).

Subsequently, as shown in FIG. 33, the information processing device 1 transmits the parameter D from the parameter A and the position D from the position A to the information processing device 2 which are additional information corresponding to the number of holdings (S42, S43). Then, the information processing device 2 stores the parameter D from the parameter A and the position D from the position A to the position D transmitted from the information processing device 1 as data included in the data DT 21. After that, as shown in FIG. 34, the information processing apparatus 2 includes the expected data A (1) to the expected data A (4) in the data DT21 based on the parameters A to D received from the information processing apparatus 1. It is generated as data to be processed (S62).

Next, as shown in FIG. 35, the information processing device 1 moves the parameter A, the test data A (1), and the position A from the data DT 11 to the data DT 12, and transfers the test data A (1) to the information processing device 2. (S84, S85, S113). After that, the information processing device 2 identifies the information set at the position indicated by the common position information 244 for the expected data D (1) from the expected data A (1). Then, the information processing apparatus 2 uses the expected data A (1) to the expected data D (1) as expected data in which the information set at the position indicated by the common position information 244 matches the test data A (1). The expected data A (1) is specified (S124).

Subsequently, as shown in FIG. 36, the information processing apparatus 2 transfers the specified expected data A (1) and the parameters A and the position A corresponding to the expected data A (1) from the data DT21 to the data DT22. Move (S125, S126). Then, the information processing device 2 compares the test data A (1) transmitted from the information processing device 1 with the expected data A (1) in FIG. 35 (S133).

After that, as shown in FIG. 37, the information processing apparatus 1 generates test data A (2), which is the next packet of the test data A (1), as the data included in the data DT 12 (S91). Further, the information processing apparatus 2 generates the expected data A (2), which is the next packet of the expected data A (1), as the data included in the data DT 22 (S135).

Next, as shown in FIG. 38, the information processing device 1 transmits the test data A (2) to the information processing device 2 (S113). Then, the information processing apparatus 2 compares the test data A (2) with the expected data A (2) (S133).

After that, as shown in FIG. 39, the information processing apparatus 1 generates test data A (final), which is the next packet of test data A (2), as data included in the data DT12 (S91). Further, the information processing apparatus 2 generates, for example, the expected data A (final) which is the next packet of the expected data A (2) as the data included in the data DT 22 (S135).

Then, as shown in FIG. 39, the information processing apparatus 1 generates the parameter H and the test data H (1) as the data included in the data DT 11 (S95, S96). Further, the information processing apparatus 1 generates the position E which is the position information 145 indicating the unique information in the test data H (1) from the test data E (1) as the data included in the data DT11 (S101, S102, S103). ). After that, the information processing apparatus 1 overwrites the parameter E and the position E with respect to the test data A (final).

Next, as shown in FIG. 40, the information processing device 1 transmits the test data A (final) to the information processing device 2 (S113). Then, as shown in FIG. 40, the information processing apparatus 2 compares the test data A (final) with the expected data A (final) (S141).

After that, as shown in FIG. 41, the information processing device 2 stores the parameter E and the position E overwritten by the test data A (final) transmitted from the information processing device 1 as the data included in the data DT 21. (S152). Then, the information processing apparatus 2 generates the test data E (1) from the parameter E as the data included in the data DT21 (S153). Further, the information processing apparatus 2 deletes, for example, information related to the test data A (parameter A, expected data A (final) and position A) from the data DT 22 (S155).

As a result, the information processing device 2 can specify the expected data 241 that needs to be compared with the test data 144 received from the information processing device 1. Therefore, in the information processing device 2, there is a difference between the transmission order of the test data 144 performed by the test target unit 12 of the information processing device 1 and the arrival order of the test data 144 in the disk driver 23 of the information processing device 2. Even if this is the case, it is possible to determine the normality of each test data 144.

The above embodiments can be summarized as follows.
