Abstract

PURPOSE:To automate test and verification, and simultaneously, to attain the abbreviation of verifying work and the improvement of verification precision by generating a control card for checking an item value by using a code definition file and a record definition file, and collating and comparing this with a test result file, and extracting abnormal value data for only a different item. CONSTITUTION:The code definition file (step 102) in which the item value and the meaning of every item of a code table are registered, the record definition file (step 103) in which the item name and the attribute, etc., of data are registered, and the test result file (step 106) in which a result after the execution of a test is registered are generated, and an item value checking file (step 105) for detecting an abnormal value in the test result file is generated on the basis of the code definition file and the record definition file, and the abnormal value data is extracted comparing this item value checking file with the test result file (step 107).

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 for outputting an abnormal item of the created computer program.

[0002]

2. Description of the Related Art FIG. 5 is a flow chart showing a conventional procedure for creating a computer program and a test verification method.

First, a computerized requirement specification is created in response to a request from a user, and a systematization range is determined based on the computerized requirement specification. On the other hand, the designer encodes the information so that it can be processed by the computer. In this work, a person in charge creates a code table by hand, and this is a table showing correspondences such as what meaning "A" of "customer number" has. Then create a program specification. This corresponds to the work at the previous stage when actually creating the program.

After this, the programmer executes the program production coding with reference to the created program specifications. The computer program thus completed is subjected to a test as to whether or not the function is exerted as desired, and the result is stored in a test result file. This test result file contains various items. Further, the contents of the test result file are printed (printed out), and the wrong item (abnormal value) is found by comparing the contents with the code table. Then, the program is corrected for the abnormal part.

[0005]

However, in the above-mentioned conventional technique, since the test result is manually verified by comparing the output contents of the test result file with the code table, the test verification is very difficult. It takes a lot of time and requires a great amount of labor for the worker.
Also, it is easy to overlook because it depends on human hands,
There were cases where the abnormality could not be completely eliminated.

It is therefore an object of the present invention to provide a computer program test verification method that automates the verification work, shortens the verification work, and completely eliminates abnormal values.

[0007]

In order to achieve the above object, according to the present invention, a code definition file in which item values and meanings of each item in a code table are registered, and item names and attributes of data are registered. Item values for detecting the abnormal value in the test result file based on the code definition file and the record definition file. Create a check file,
The item value check file is compared with the test result file to extract abnormal value data.

Further, in order to omit the creation of software for the main part of the verification process and to enhance versatility, Structure / Quality Language (SQL) is used for creation of the item value check file, and comparison / extraction is performed. A relational database can be used for processing.

[0009]

According to the above means, the control card for checking the item value is generated using the code definition file and the record definition file, and this is saved as the check file, and this file and the test result file are compared and compared. Is performed, and abnormal value data is extracted and extracted for different items. Therefore, the test verification can be automated, and the verification work can be shortened and the verification accuracy can be improved.

[0010]

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 the computer program test verification method according to the present invention. In the figure, S means a step.

First, the code definition is interactively input to the computer for registration (S101). At this work stage, the contents of one code as shown in FIG. 2 are displayed on the monitor screen attached to the computer. A "code definition file" is created based on the registered contents (S10).
2). This "code definition file" has the contents as shown in FIG. 3, and the data name, the attribute, the item value and the comment are registered (since the normal value is registered in step 102). This is input based on the code table (or information similar thereto) shown in FIG.

On the other hand, the item name, the number of digits, the attribute, etc. of the data item are created as a "record definition file" (S10).
3). Create a question sentence (QUERY sentence) using this "record definition file" and "code definition file",
Based on this, a "control card" for checking item values having the contents shown in FIG. 4 is created (S104). The question sentence is used to create a “control card” to be described later for detecting an abnormal value from the “test result file”, and the data name 1 (quoted from step 103) and the code definition 2 (quoted from step 102). ) Consists of.

Then, each of the "control cards" created in step 104 is saved as an "item value check file" (S105). Then, the "item value check file" and the "test result file" (S106) described with reference to FIG. 5 are compared and referred to for each code, and a mismatch is determined to be abnormal (S107). Only the data is printed out (or displayed on the monitor) (S108). Note that this "test result file" is premised on a relational database, and if it is not a relational database, the "test result file" needs to be converted to a relational database. In addition, the printout in step 108 can be obtained in a short time of about ten minutes from the start of execution of the verification process, and from this result, the abnormal part of the program can be immediately grasped, and corrections, changes, etc. Can be done quickly.

The program for executing step 107 is a relational database software used for storing and referring to data, such as IBM.
Software "QMF (DB2)" marketed by the company
"SQL (Structured Query Language)" as a language for referring to relational databases using
To use.

[0016]

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

In the computer program test verification method of the first aspect, a code definition file in which item values and meanings of each item in the code table are registered, a record definition file in which item names and attributes of data are registered, and Create each test result file in which the results after the test execution are registered, and create the item value check file for detecting the abnormal value in the test result file based on the code definition file and the record definition file. By comparing the item value check file with the test result file and extracting the abnormal value data, the test verification can be automated, and the verification work can be shortened and the verification accuracy can be improved. become.

In the computer program test verification method according to the present invention, the structure / quality language (SQ) is used to create the item value checking file.
Since L) is used, commercially available software can be used, program creation can be simplified, and versatility in use can be improved.

In the computer program test verification method according to the present invention, since the comparison and extraction processing uses a relational database, the preparation of programs for the comparison and extraction processing can be omitted, and the computer program can be used. The versatility of can be improved.
