Abstract

PURPOSE:To generate the test data at one time to the data area where plural types of items are defined by defining the items and designating the number of data to be generated via a user for generation of a test data in the same data area where plural types of items are defined. CONSTITUTION:A source program is read into a source file 1 and an item definition analyzing means 2 analyzes a data part. The data generating instruction inputted from a keyboard 4 is stored in a generating instruction information storage part 5 together with the item definition information 3. The designation of the test data output frequency is inputted via the keyboard 4, and the number of generated test data is designated per repetition together with the repeating frequency. These designated factors are stored in an output frequency information storage part 6 together with the data names. The information stored in both parts 5 and 6 are referred to by a test data generating means 7, and the generated test data is outputted to a file 8 and stored there. Thus it is possible to generate the test data to all patterns with no rearrangement required.

FIG. 2 is a flowchart showing the flow of control in this embodiment.

FIG. 3(a) is a part of the data portion of the source program used in this embodiment, and FIG. 3(b) is a diagrammatic representation of FIG. 3(a). 01 to 03 are level numbers, DATA-
AREA, DATAI, A.

B, C... are data names, p, c... are data, of which X, 9. N indicates alphanumeric characters and numbers 9 written in Japanese.

FIG. 4 shows the contents of the item definition storage section 3.

Information read by this device from the source program stored in source file 1 is stored here, and 9
is the data name to which the item belongs, 10 is the item name, 11 is the digit position of the item, 12 is the character type of the data to be generated (here, it is divided into alphanumeric characters and numbers 9 Japanese according to the constituent characters of the data), 13 indicates the number of digits for each item of data.

FIG. 5 shows the contents of the generation instruction information storage section 5. As shown in FIG. 9
~13 inputted from the item definition storage unit 3, 14.
Step 5 is what is input from the keyboard 4, 14 is the test data generation method (constant generation or random number generation), and 15 is the definition generation which is the value that is actually output as test data only in the case of constant generation. The data for each are shown.

FIG. 6 shows the contents of the generation number information storage section 6. 1
6 indicates the data name for each item definition, 17 indicates the number of test data output per repetition, and 18 indicates the number of repetitions. 4 are respectively input.

FIG. 7 shows a data generation section that generates the test data shown in the test data generation means 7 of FIG. In the figure 1
Reference numeral 9 indicates a repetition number counter stored in the generation number information storage unit 6 shown in FIG. 1, 20 indicates an output number counter stored in the generation number information storage unit 6 shown in FIG. 1, and 21 indicates the number of times data is actually generated. The test data generation areas are shown respectively.

FIG. 8 shows test data actually generated in this embodiment.

-〇- Next, using Figures 1 to 8, we will explain the series of operations from input of the source program to generation and output of test data using Kobol's rREDEF.
This will be explained using the INEsJ phrase. According to the procedure of a in FIG. 2, that is, steps 31 to 33, a source program as shown in FIG. 3 is read into the source file 1 of FIG. 1. Next, the data section is analyzed by the item definition analysis means 2 shown in FIG. Here, the device is rREDEFINES
” (underlined part in FIG. 3(a)), the data start position is positioned and stored at the same digit position as DA and TAL written next to rREDEFINEsJ, as shown in FIG. 4. Next, the generation instructions entered from the keyboard 4 that give generation instructions for each item include the data generation method (constant or random number), the actual data to be output if the generation method is constant, and the generation method is random number. It is stored in the generation instruction information storage section 5 of FIG. 1 together with the item definition information 3 of FIG. 1.

Next, specify the number of test data outputs. The designation of the number of test data outputs is entered from the keyboard 4, and as shown in FIG. 6, the number of test data generated per repetition and the number of repetitions are designated for each item. These two pieces of information are stored in the output count information storage unit 6 together with the data name.

Next, test data is generated and output according to steps 34-37 in FIG. Generation instruction information storage unit 5 in FIG.
The information stored in the and generation number information storage section 6 is referred to by the test data generation means 7. FIG. 7 shows the contents, and if the generation instruction of the character type 12 is a constant, the contents of the constant generation data 15 are tested against the generation image of the constant generation data 15 in the generation instruction information storage unit 5. It is taken into the data generation area 21 as it is.

If the generation instruction for character type 12 is a random number, the number of digits in the item is 1.
A random number having the same number of digits as 3 is generated in the test data generation area 21. When one piece of data is generated, 1 is subtracted from the value of the repeated sitting position counter of the output number counter 20, and the next data is generated. When the value of the output count counter 20 reaches O, the value of the output count 17 of the next data is taken in and data generation for the next item definition is started. In this embodiment, when two pieces of data are generated for the item definition of DATA1, the value of the output count counter 20 becomes 0, and then data is generated for the item definition of DATA2. Then, when five DATA2 are generated, since DATA3 is specified as 0, the process returns to generating DATA1. At this time, 1 is subtracted from the value of the repetition counter 19.

In this way, when the repetition of 2 DATA1 and 5 DATA2 is repeated 35 times, the generation of the strike data is completed. The generated test data is output and saved in 8 files.

〔Effect of the invention〕

As explained above, the present invention enables the user to generate test data by specifying the item definition and the number of generated data in the same data area where multiple types of item definitions are made. Test data can now be generated at once for data areas that have multiple types of item definitions, which previously had to be done more than once because it could only be generated for definitions, improving the efficiency of test data generation work. This has the effect of making it possible to
