Abstract

(57) [Abstract] [Purpose] When testing the created program, improve the productivity of program creation by automating the human work part in the test and systematizing the test procedure. According to this method, the test program source extraction means 1 extracts the tabular information, generates tabular test item information 5, and outputs the execution result to the tabular test item information 5 by step execution 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a test execution system for testing a created program based on a set item and guaranteeing reliability.

[0002]

2. Description of the Related Art A program test is used to judge whether the program operates normally and to examine how much reliability the program under test can guarantee. As a means to do this, function information is extracted from the program under test, data values are input in the form of a list, and then test cases are set to automatically generate a test program, which is then executed and tested.
A conventional technique of this type is described in Japanese Patent Laid-Open No. 2-247742.

[0003]

In the prior art, the test program for executing the test items was generated. Therefore, once the test program is generated, the data in the list form is used to correct input errors and omissions. It is necessary to input and modify and generate the test program again, so
It takes time and becomes inefficient.

[0004]

[Means for Solving the Problems] As a means for solving the above-mentioned problems, while adding / correcting the tabular information of the test items extracted from the program source under test, the target items are executed according to the execution conditions of the table. The test program was step-executed, the execution result was output to an outline table, the table was completed, and the execution result was confirmed.

[0005]

In the present invention, by adding / correcting the tabular information extracted by the test program source extraction means 1 and executing the test program step by step, the condition input can be performed each time. Since the execution result is output to the outline, the result can be confirmed in real time, and therefore it is easy to judge whether it is right or wrong.

[0006]

FIG. 2 shows a first embodiment of the program test execution system according to the present invention.

In the first embodiment, the program under test is step-executed with respect to the tabular information made up of the variables as the execution condition and the confirmation condition extracted from the program under test. Since step execution is performed, the values of variables other than arguments can be set even after the start of execution. At the end of execution, the resulting value is written in the confirmation condition column 2j. Similarly, when all the test execution condition item cases are completed, the table is completed. The correctness of the program is judged from the execution results.

The specific format of the tabular test item information 5 described above is shown in FIG.

In FIG. 3, the codes shown in Table 1 are set in the code section 2a.

[0010]

[Table 1]

A variable name is set in the variable name portion 2b, and a type name of the variable name is set in the type portion 2c with the contents extracted from the source program under test. Test case selection section 2
In the d, one vertical column represents one test case, and necessary values are input to the case to create a case.

As an example of the program test according to this method, a program written in C language shown in FIG. 5 will be described.
This program is 1, if the value entered in the argument is odd,
It returns 0 if it is even. When this test method is executed for this program, CODE is displayed in line 2e.
Input the function name as prompted for the NAME field of the name FUNC. Variables serving as execution conditions and confirmation conditions are extracted from the input function name, and the test program source extraction means generates a template of information of tabular test items, FIG. When the variable to be confirmed is not set, or when the variable that does not need to be confirmed is set, the table can be added or modified. Looking specifically at FIG. 4, line 2
Since the input is required in the CASE field of e, the case number is input (hatched part in FIG. 4, case number 1). In line 2h, the CODE name PARM is set, the argument is set, the argument name is set in the NAME column, and the model name is set in the TYPE column. The line 2j is the CODE name DC, and the return value of the function is confirmed, so the name return_value is set in the NAME column. The name return_value set here is
As a variable for confirming the return value of the function in this test method, it is always set in the NAME column with the name return_value. When each item is set as described above, the argument value of PARM in line 2h is requested to be input. Therefore, in order to execute the routine under test, the set value is input in the CASE column (see the hatched portion in FIG. 4 and the set value is 9). ). When the program is step-executed, D in line 2j, which is the confirmation condition column, is displayed.
The value of the execution result is written in the CASE column of the C code (hatched portion in FIG. 4, the execution result value is 1). This completes one case and moves on to the next case. To continue the test, enter the case number and other items as well. The correctness of the program is judged based on those results.

[0013]

According to the present invention, since step execution is performed according to the execution condition of the tabular information extracted from the source program to be tested, data can be set even after the execution, so that data leakage can be prevented. It is possible to prevent it, and since the execution result is real-time, it is possible to find an input error. In addition, by minimizing the human work and writing the execution result, it is possible to leave the execution result and to significantly reduce the work time.
