Abstract

PURPOSE:To automate work up to the execution of a test, and to attain the abbreviation of verifying work and program verification based on actual data. CONSTITUTION:A test case-setting file S107 is generated by reading the data value of an item corresponding to a test item selected in a step S103 out of a code definition file S105, and a test data file S109 is generated on the basis of test data generated on the basis of this in the step S108. On the other hand, in the case that 'setting of new data extraction condition' is decided in the step S104, the extraction condition of data to be extracted out of an actual data file is supported (S110) for the item selected in the step S103. The test case-setting file is generated on the basis of this (S111). The test data is generated in the step S113 on the basis of this file and an actual data file S112 in which the actual data (existing data) is registered, and the test data file S114 is generated on the basis of this.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a test verification method for a computer program, which enables verification of a created computer program test based on data, particularly on actual data.

[0002]

2. Description of the Related Art FIG. 10 is a flowchart showing a conventional computer program manufacturing process and a test verification method for the program. In addition, S in the figure means a step.

First, a designer creates a program specification (a computerization requirement specification from a user) (S
201), according to which the programmer performs coding for program production (S202), and this is saved as a source program (S203).

When conducting a test on the created program, the programmer first sets a test case (S204). This test case setting is a process of extracting and registering the input content for a certain data name of the program and the result that appears in response to it, in other words, setting a partial simulation part of the program. Is. Then, the input data (or test data) is actually input (S205).
The "test data file" is created by the above (S
206).

Then, a program test according to the input data is executed using the "test data file" (S207). The test result is printed out (S208), and the printed matter is inspected in order from the beginning to the end by the programmer, and the abnormal portion is searched silently. When an abnormal portion is found, the programmer makes a program correction for the portion.

FIG. 11 is a flowchart showing the test data setting process (step 204) in FIG.

First, a record definition file consisting of item names and attributes of data items is created (S301). Items are selected based on this file (S302). This processing is to select an item to be tested (that is, to simulate) and describe the data content. Next, a test case setting table is created (S303), and the test data input process shown in FIG. 10 (S20) is performed.
5) The test data file creation (S206) is sequentially executed. All of these processes are performed manually by the programmer.

[0008]

However, in the above-mentioned prior art, in executing the test, all the steps from setting the test case to creating the test file are performed manually, and it takes a lot of time for test verification. It was a great effort for the worker. In addition, there are cases in which an abnormality cannot be completely eliminated because it is easy to overlook because it depends on human hands.

Therefore, an object of the present invention is to provide a test verification method for a computer program that automates the work up to the test execution and shortens the verification work.

Another object of the present invention is to provide a test verification method for a computer program that enables program verification based on actual data.

[0011]

In order to achieve the above object, the present invention creates a code definition file in which item values and meanings of data items are registered, and data of items corresponding to selected test items is created. A value is read from the code definition file to create a test case setting file, and a test data file is created based on the test data generated based on this.

The above-mentioned purpose is to create an actual data file in which actual data is registered, set extraction conditions corresponding to selected test items, create a test case setting file based on this, and create a specified test case. It is also achieved by reading the data corresponding to the above from the actual data file, generating test data, and creating a test data file based on this test data.

[0013]

According to the above means, the item value or the extraction condition is set according to the selection of the item to be tested, the test case setting file is created by referring to the code definition file or the actual data file, and based on this file Test data is created, and a test data file is created. Therefore, it is possible to automate the work up to the execution of the program test, shorten the verification work, and perform verification close to the actual operation.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a flow chart showing an example of processing for achieving a computer program test verification method according to the present invention.

First, the test case number is set (S101), and the display screen at this time is shown in FIG.
The file (record definition file) to be used is specified by this setting. Next, the item of the file specified in step 101 is displayed on the monitor screen from the record definition file (S102) in which the item names and attributes of the data items are registered (S102).
103). In this display example, "S" in the leftmost column in the screen
Indicates that it has been specified. Then, the item to be tested is selected from the contents of the display screen. Next, it is determined whether the last digit of the test case number is "item value setting" or "new data extraction condition setting".

In the case of "item value setting", an item value setting process is performed (S106). This process is step 103.
The code definition file (S1) in which the item value and meaning of the item selected as the normal value and the data item as a normal value are registered
The code value contents (= data value of the item selected in step 103) are set as shown in FIG. 4 based on the items in (05) and the setting result is registered as a test case setting file. (S107). If an abnormal value is desired to be set, the code value may be input from the keyboard.

Test data is created using the test case setting file (FIG. 5) (S108), and a test data file is created as shown in FIG. 12 based on the creation result (S109). The item names and the like in FIG. 5 are designated in step 103, and the position 1 of the file is grasped for each item, and the item value 4 is set in the file according to the number of digits 2 and type 3. Using the test data file created in this way, the test is executed (S207) as shown in FIG. 10, and the test execution result is printed out (S208).

On the other hand, when the "new data extraction condition setting" is judged in step 104, the display screen of the contents shown in FIG. 6 is displayed for the item selected in step 103, and the data extraction from the actual data file is extracted. A condition is designated (S110). A test case setting file (FIG. 7) is created based on this (S111). The test data shown in FIG. 9 is created based on this file and the actual data file (S112) in which the actual data (existing data) is registered (S113). In FIG. 7, 5 is the contents specified in step 101, 6 and 7 are the contents selected in step 103, and 10 is the extraction condition specified in step 110.

In the processing in step 113, first, the actual data storage place is grasped, and then the actual data file is read from FIG.
The actual data shown in is read. Then, the data contents of the position 8 and the digit number 9 of the actual data file are compared with the item value 10 for each item, and if they are the same, this is written as a test data file (S114). For example, when the actual data as shown in FIG. 8 is given and the test data is created based on the extraction condition of FIG. 6, it becomes as shown in FIG. A test is executed using the test data file created in this way as shown in FIG. 10 (S207).
Then, the test execution result is printed out (S20).
8).

As is clear from the above, in this embodiment, verification is performed using data (temporary data) other than actual data in steps 104 and 106 to 109, whereas in steps 104 and 110 to 114, verification is performed. We are verifying with real data.

[0022]

Since the present invention is configured as described above, it has the following effects.

In the computer program test verification method according to the first aspect, a code definition file in which item values and meanings of data items are registered is created, and data values of items corresponding to the selected test item are stored in the code definition file. The test case configuration file is created by reading from the test data file, and the test data file is created based on the test data generated based on this, so it is possible to shorten the time required to execute the test of the program, simplify the check and The quality of the program can be improved.

In the computer program test verification method according to the second aspect, an actual data file in which actual data is registered is created, extraction conditions corresponding to selected test items are set, and a test case setting file is created based on the extraction conditions. Is created, the data corresponding to the specified test case is read from the actual data file to generate the test data, and the test data file is created based on this test data. It is possible to shorten the time until, simplify the check, improve the quality of the program, and verify the actual operation based on the actual data.
