Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an existing test program reusing method for reusing a large number of test programs for an existing data processing program in a program test of a data processing program under a new operating system.

[0002]

2. Description of the Related Art When reusing a test program of an existing program in a program test of a program under test that is compatible with a program under the existing operating system, the language equivalent to the description language of the test program is used. If exists under the new operating system, it is possible to re-translate the test program under the new operating system and reuse it.

However, this method is premised on that a language equivalent to the description language of the existing test program exists under the new operating system. Therefore, if there is no equivalent language, the language existing under the new operating system. Therefore, it becomes necessary to rewrite many existing test programs.

Therefore, there is a method of reusing by creating a language conversion program such as a converter and converting the existing test program so that it can operate under the new operating system.

[0005]

However, creating a language conversion program such as a converter requires a great deal of time to create a language conversion program. Therefore, many existing test programs are all installed under the new operating system. In some cases it was more efficient to rewrite in language.

An object of the present invention is to provide an existing test program reuse method capable of reusing a large number of existing test programs under a new operating system without creating a language conversion program.

[0007]

In order to achieve the above object, the present invention operates a plurality of existing test programs individually with respect to an existing data processing program, and is created in the main memory for each operation. The input information and the output information of the existing data processing program are sequentially collected in an external storage device, and under the new operating system, the input information collected in the external storage device is sequentially read and given to the new data processing program. As a result, a new test program that compares the output information output by the new data processing program with the output information of the existing data processing program collected in the external storage device is created, and the program of the new data processing program is created by this new test program. I tried to do a test.

[0008]

According to the above means, the input information itself created by the existing test program is given to the program under test under the new operating system. Then, the information output by the program under test is compared with the output information determined to be valid when the existing test program is operated.

Therefore, a large number of existing test programs are reused under the new operating system without creating a language conversion program, and the same input information as the existing test programs is given to the test program, and the test program is supplied to the test program. Quality assurance equivalent to that of the existing program under test can be performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, FIG. 2 is a block diagram of input / output information in FIG. 1, and FIG. 3 is a flow chart showing the operation of the new test program in FIG.
FIG. 4 is an output example of the test result list in FIG.

First, the structure of the existing operating system environment will be described.

The existing data processing program 1 is a processing program for generating output information from given input information. The existing test program 2 is a program for testing the existing data processing program 1, and creates and gives input information 3 to the existing data processing program 1, and as a result, output information 4 output by the existing data processing program 1.
Input information 3, output information 4
Is a program having a function of recording the data in the external storage device 5.

A large number of existing test programs 2 exist for each test condition of the existing data processing program 1.
In FIG. 1, it is shown by 2a to 2n.

Next, the configuration of the new operating system environment will be described.

The external storage device 6 is a device for recording input / output information when the input information 3 and the output information 4 recorded in the external storage device 5 are transferred to a new operating system environment.

The new data processing program 7 is a program under the new operating system environment, which operates in the same manner as the existing data processing program 1. The new test program 8 is a program for testing the new data processing program 7 using the input information 3 and the output information 4 recorded in the external storage device 6. Test result list 9
Displays the execution result of the new test program 8.

The input information 3 in FIG. 1 is composed of a record length 21, control information 22, and test data 23, as shown in FIG. 2 (a). The control information 22 stores a processing command to the data processing program 1.

The output information 4 is composed of a record length 24 and edit data 25, as shown in FIG. 2 (b). The edit data 25 stores data created by the existing data processing program 1 based on the control information 22 and the test data 23 of the input information 3.

A method of reusing the existing test program 2 having such a configuration will be described in detail.

First, the existing test program 2 is individually operated in the existing operating system environment, and the input information 3 created by the existing test program 2 on the main storage device.
As a result, the existing data processing program 1 collects and records the output information 4 output on the main storage device in the external storage device 5.

Next, the input information 3 and the output information 4 recorded in the external storage device 5 are transferred to the new operating system environment and recorded in the external storage device 6.

When the preparation for operating the new test program 8 under the new operating system environment is completed in this way, the new test program 8 is operated. The operation of the new test program 8 will be described with reference to FIGS.

First, the input information 3 and the output information 4 recorded in the external storage device 6 are read into the record buffer 31 and the record buffer 32, respectively (step 30).

Next, control is passed to the new data processing program 7. At this time, the input information 3 of the record buffer 31
A record buffer 33, which is an area for storing the output information 10 generated by the new data processing program 7, is provided (step 301).

Then, in the new data processing program 7,
The edit data 25 is created from the test data 23 based on the content of the control information 22 of the received input information 3, and is stored in the record buffer 33 as the output information 4.

When the control returns from the new data processing program 7, the new test program 8 compares the output information 10 stored in the record buffer 33 with the output information 4 stored in the record buffer 32 (step 30).
2).

If the comparison result is correct, the result of FIG.
The normal result list 90 shown in (a) is output (step 3
03), if different, the abnormality result list 91 shown in FIG. 4B is output (step 304).

When the operation of the new test program 8 is completed in this way, the test equivalent to one existing test program 2 (for example, 2a) is completed for the new data processing program 7.

By repeating the above procedure from the operation of the existing test program 2 to the end of the operation of the new test program 7 for all the existing test programs 2b to 2n, all the existing test programs 2a for the new data processing program 7 are performed. A test equivalent to ~ 2n can be performed by the new test program 8.

The specific structure of the new test program 8 is not limited to that described above, and it goes without saying that it can be modified as appropriate without departing from the spirit of the present invention. The input information 3 and the output information 4 may be recorded in the external storage device 5 not only in the existing test program 2 but also in the existing data processing program 1. Furthermore, the contents of the input information 3 and the output information 4 and the recording method in the external storage devices 5 and 6 are arbitrary.

[0032]

As described above, according to the present invention, a plurality of existing test programs are individually operated with respect to the existing data processing program, and the input information created on the main storage device and the existing data are created for each operation. The output information of the data processing program is sequentially collected in an external storage device, and under the new operating system, the input information collected in the external storage device is sequentially read and given to the new data processing program. A new test program that compares the output information output by the data processing program with the output information of the existing data processing program collected in the external storage device is created, and a program test of the new data processing program is performed by this new test program. Since it was set to the new operating system without creating a language conversion program. Re-use a large number of existing test program in the absence, it is possible to perform the existing the test program and the equivalent of quality assurance with respect to the test program.
