The present invention relates to a program test processing system, and in particular, for testing programs having multiple interfaces using different data formats, interface information corresponding to each different data format is managed in a file, and any interface information can be This invention relates to a test processing system for programs capable of processing data.

[Conventional technology]

FIG. 4 shows the configuration of a conventional program test processing system.

In Fig. 4, 1 is the program under test, and during execution, data of different interfaces ■/Fl, I/F2
．． I/F3. Send I/FX.

2 is a test program that executes test processing.

3. 5.6 is the data of different interfaces I/Fl, I/F2. I/F3. This is a subroutine called by the test program 2 to process I/FX, and is called a processing function here.

The program under test 1 has been developed, for example.

The program is a program that has multiple interfaces with different data formats, and when a test is executed, the data I/F1.
I/F2. I/F3. I/FX (hereinafter collectively referred to as I/FX)
F (denoted as n) is transmitted.

Here, the data format refers to the data structure or data format of transfer data, and means, for example, a set of specifications regarding the presence or absence of two individual data items and their data length in data including a plurality of data items. Here, the program under test 1 is assumed to have a function of transmitting and receiving data to and from a plurality of terminals or devices having different data formats.

All data sent by the program under test 1 during the test process is passed to the test program 2.

When the test program 2 identifies the interface type of the received data, it calls a specific processing function (subroutine) prepared for processing that data.For example, for data I/F1, the test program 2 calls the I/F1 Call processing function 3 and start processing.

The called I/Fl processing function 3 executes simulation of display processing, response (input) processing, etc. specified for data ①/F1. This allows testing of programs without actually connecting terminals with various interfaces.

In conventional test processing systems, separate processing functions are prepared for each type of interface data format, and each processing function expands the data sent by the program under test into memory according to the data format specific to that interface. Was.

[Problem to be solved by the invention]

In conventional test processing systems, when testing a program that has multiple interfaces with different data formats, at least one function (subroutine) must be prepared for each interface to process the data, and each function There was a problem in that the processing in the test processing system was duplicated, the program scale of the test processing system became large, and the number of development steps increased. Furthermore, if a program interface is added or changed, a corresponding function must be added or changed, and the test processing system is greatly affected by program modifications, resulting in a problem that the test processing system has low versatility.

SUMMARY OF THE INVENTION An object of the present invention is to provide an efficient test processing system that can flexibly respond to additions and changes to interfaces of a program under test and has a relatively small program scale.

[Means to solve the problem]

In the present invention, definition information regarding each data format of a plurality of interfaces is stored in a file so that it can be referenced by a function, and when the function is called from a test program, the function refers to the definition information of the corresponding interface and performs processing based on the definition information. It expands the data to be processed onto memory. As a result.

Functions can be made common to each interface.

FIG. 1 is a diagram showing the basic configuration of the present invention.

In FIG.

(2) is a program under test that has multiple interfaces with different data formats.

2 is a test program that is coupled to the program under test l to perform test processing.

7 is called by test program 2.

This is a data processing function of a subroutine common to multiple interfaces that processes interface data.

8 is a definition information file that stores definition information for each different data format of a plurality of ink faces.

Reference numeral 9 denotes a file access function of a subroutine called by the data processing function 7 to retrieve definition information of the data format of the corresponding interface from the definition 1 report file 8 to 8.

The data processing function 7 is a parameter that specifies the data format of data received from the program under test 1.

The meter is passed to the file access function 9 to request a search. The file access function 9 searches the definition information file 8 for target definition information according to the parameters, and passes it to the data processing function 7.

The data processing function 7 interprets the definition information.

Based on this, the data received from the program under test is processed.

[Effect]

As shown in FIG. 1, according to the present invention, when the data formats of a plurality of interfaces of a program under test are different, a definition information file 8 is created in advance from definition information of each of those data formats, and Data processing function 7
By preparing a common interface corresponding to the type of interface processing such as display and response, it is possible to easily support an interface of any data format.

In FIG. 1, the program under test l has four types of data formats: I/F1, I/F2゜1/F3. l
/Send while executing FX. When the test program 2 receives these data, it calls the data processing function 7 for processing.

The data processing function 7 processes those data (1/F1, I/
F2. I/F3. A parameter specifying the data format of the I/FX) is passed to the file access function 9, the corresponding definition information is obtained, the data is processed, and control is returned to the test program 2.

If there are any additions or changes to the interface.

This can be dealt with by adding or changing the contents of the definition information file 8.

〔Example〕

The present invention will be explained in detail with reference to FIGS. 2 and 3.

FIG. 2 shows the structure of the definition information file 8. Data I/F11/F2 of each interface.・・・
..., definition information indicating the data format of I/Fn is I/F 1 identifier, I/F 2 identifier, ...
・', is managed using the 1/Fn identifier as a key,
Each includes data 1 to data n as individual definition data.

FIG. 3 is an explanatory diagram of the operation of the embodiment of the present invention. Note that each element shown in FIG. 3 is the same as that shown in FIG. 1. Also, ■ to ■ in the figure indicate operating procedures.

First, when the program under test 1 sends data (3) during execution, the test program 2 receives the data (3).

The test program 2 calls the data processing function 7 at (2) and passes the received data.The data processing function 7 calls the file access function 9 at (2) with the identifier of the received data as a parameter to search the definition information file 8.

The file access function 9 returns the definition information of the search result to the data processing unit 7 in ■.The data processing function 7 expands the received data in a memory (not shown) according to the definition information, and displays the data in ■. As a result, when data is input from the tester, response processing is performed in step 3, and the response data is returned to the test program.

The test program 2 transmits the response data to the program under test 1 in (2), and the program under test 1 receives the response data and continues processing.

In this case, the tasks and operations required by the tester are as follows.

・Creating a definition information file ・Sending data from the program under test ・Receiving data by the test program ・Responding to data (data input) ・Sending data to the program under test [Effects of the Invention] According to the present invention, multiple For this interface, only a small number of data processing functions are required, such as those for data display and response, making the program more compact and reducing development man-hours.

In addition, to add or change an interface, all you have to do is add information to the definition information file or change the parameters in the definition information file, so the impact of modifying the program is small and the amount of work can be reduced. . Therefore, it is possible to easily perform tests using various data format patterns by adding and changing the interface at the time of testing.
