JPS58222343A - Automatic discriminating system of difference of data - Google Patents

Abstract

PURPOSE:To feed back easily and efficiently the result of discrimination, by comparing an input data with a reference data for discriminating difference of the input data, and discriminating the difference of the input data for relieving the load of the operator. CONSTITUTION:The result of a program test of a test system 6 is stored in a data file 7 and data independently of the content of test and the permissible difference in a reference data file 8 are all masked in advance. A discriminating processor 9 reads out data from the files 7, 8, compares successively the difference of characters at a comparison section 10, and the result of discrimination is stored in a file 12. A mask processing section 11 detects a mask mark in a reference data during the operation, and if the mask mark is detected, it is controlled that the comparison is skipped. The file 8 supplies the reference data required at all times to the discrimination processor 9 in this way, allowing to prevent erroneous discrimination of difference.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a method for testing equipment or programs in a data processing system by repeatedly performing tests on a single or multiple equipments using the same test data source. In such cases. Regarding the method of automatically determining differences by comparing a large number of input data of the same type with reference data, especially when the input data includes management data or variables such as date and time that are irrelevant to the determination or are convenient to exclude. .

The present invention relates to an automatic determination method in which such information is masked in the determination process so that only the original determination target data can be determined.

Technical background In general, large amounts of test result data are often output in program tests such as O8, but in the past, most of the data was judged visually, which required a lot of labor and effort for the tester. It was becoming a burden.

On the other hand, when considering a general-purpose system that automates the determination of whether output data is correct or incorrect, all data on the output screen may be test data, as shown in FIG.

Normally, the test is conducted because it contains data parts that are always changed every time the test is performed, such as 9 hours on 9 days.
When performing a one-on-one check for differences between such test result data and reference data by sequentially scanning the screen, the result is always a discrepancy.

Judgment information about the required data part cannot be obtained. Furthermore, a similar problem occurs when there is a simple partial modification to the test data or program.

To solve this problem, on the output screen.

Although it is possible to specify the area of data to be tested each time, this is a one-time task and may be practically impossible.

In order to solve the above-mentioned problems, the present invention provides a simple and effective means for masking the data portion to exclude the difference determination. Compare with reference data that serves as a criterion for determining differences.

Input...In a system that determines the difference between card data.

It is equipped with a comparison section that sequentially compares the corresponding parts of input data and reference data, and a mask processing section that masks a pre-specified area in the input data to exclude it from the comparison target. Each line has a mask line display area that displays the existence of a data area to be masked, and a mask mark used to display the mask data area in the line is registered there, and the mask mark can be used to further display the data area. By filling the mask data area in the row, mask information is provided to the mask processing section, and the mask □ processing section performs the comparison of the comparison section based on the mask information:,! ! The present invention is characterized by controlling the IJJ operation and masking the comparison judgment of input data for the mask data area.

The present invention will be explained below based on nine examples.

FIG. 2 shows one embodiment of reference data having nine masks according to the present invention, and is shown as a screen image of an output list.

In the figure, 1 is an output list screen, 2 is a mask line display field, 3 is a data display field, 4 is a mask mark, and 5 is a data area to be masked.

The mask line display column 2 is used to display the presence or absence of a data area to be masked for each line, and a mask mark 4 is written at the position of each line that has a data area to be masked 5.

In FIG. 1, X and Y are exemplarily used as the mask mark 4, but any character may be used as long as it is not used in the data in each corresponding line. The characters entered in the mask line display field 2 are treated as defining the type of mask mark used in that line. Therefore, the masked data area 5 in the data display field 3 yen is always filled with that character. The characters in the line mask line display field must be filled in. Accordingly, the comparison/judgment section, which will be described later, performs masking processing.

When doing so, firstly, the characters in the mask line display field are referred to, and if the same character is detected in the accompanying data, the comparison process at that position can be omitted or the comparison result can be invalidated.

FIG. 3 is a schematic explanatory diagram of an embodiment system according to the present invention. In the figure, 6 is a test system.

7 is a test result data file, 8 is a reference data file, 9 is a test judgment processing device, 10 is a comparison section, 11 is a mask processing section, 12 is a judgment result data file, 13 is an output list, 14 is a visual check process, 15 16 indicates mask data creation processing, and 16 indicates mask data input processing.

Introduction 9 In a test system 6 (not shown), O8
Program tests and equipment tests such as the following are executed, and a test result data file 7 is created. On the other hand, a reference data file 8 that will be used as the judgment standard is created in advance. Test judgment is also performed on the control device 9 from file 7.8.

The test result data and the reference data are read out and made to correspond to each other to check for identity. The comparison unit 10 sequentially compares characters in each corresponding line.

Determine the difference. The determination result is stored in the 9-size foot result data file 12.

During the comparison and determination operation of the comparison unit 10, the mask processing unit 11 refers to the mask line display field 2 in the reference data described in FIG. here.

Since this is the first test judgment process, no mask mark is written in any line.

When the test judgment processing as described above is completed for all data in file 7.8, the judgment results stored in the 9-size foot result data file 12 are printed out, and the output list 13 is
Create.

The operator who conducted the test performs a visual check process 14 on the output list, that is, the checklist resulting from comparing the test result data file 7 with the reference data file 8, and if there are any discrepancies, they are analyzed. For data that is unrelated to the test content, such as date and time, or for data that can be overlooked due to differences in test conditions.

In order to remove it from the test determination process from the next time onwards, a process 15t is performed to create mask data as shown in FIG. 2, and the reference data file 8 is updated by inputting the mask data.

Next time, when the same type of test result data from the test system 6 is to be subjected to the determination process again.

In the previous judgment process, ``What differences should be allowed?''

Since everything is masked in the reference data file 8, the remaining data should match unless an error occurs in the test system 6. if.

If an error has occurred, the difference portion is detected by the comparator 10, written to the 9-size foot result data file 12, and displayed in the output list 13.
,.

; ρ1. .

The output list obtained this time is the same as last time.

A visual check is performed and any detected differences are analyzed. If necessary, the mask processing procedure can be performed again.

1 As described above, the reference data file 8 is created.

Always provide only the necessary range of reference data to the test judgment processing device 9 to prevent erroneous difference judgment results. FIG. 2 is a flow diagram showing a control procedure. Regarding the test result data and reference data, check the mask line display column in the reference data for each row (i), and if there is a mask mark, control the comparison so that the digit position where the mask mark exists in the same line is excluded, This is executed continuously for each row.

Effects of the Invention As mentioned above, according to the present invention, the burden on the operator required for judgment of test result data is significantly reduced, and moreover, compared to the past, it is possible to perform a more accurate difference check, and it is possible to make a 9 judgment. Feedback of results can be performed easily and efficiently.
