  Moreover, it is difficult to create test data in a complicated format with a general-purpose test data creation tool. Certainly, it is possible to create test data by identifying the structure of all records, creating data with each record as a fixed format record, and merging all records. However, when a general-purpose test data creation tool is used, the process for creating test data is complicated, and there is a disadvantage that skill is required.

  Patent Document 1 discloses a test data creation apparatus that creates test data in response to various test data creation requests. The test data creation device of Patent Document 1 performs a consistency check between test data and program data by using a copy member for defining data in the program language. If the test data creation apparatus of Patent Document 1 is used, since a general-purpose copy member is used, it is not necessary to create individual programs in response to various test data creation requests.

(Operation)
Next, the operation of this embodiment will be described in detail with reference to FIGS.

  FIG. 2 is an example of a source code of a business program created in the COBOL (Common Business Oriented Language) language for explaining the program analysis unit 11 of the parameter creation unit 1 in FIG. Hereinafter, characteristic parts of the source code of FIG. 2 will be described. In FIG. 2, parts unnecessary for the description are omitted.

  The program analysis unit 11 sequentially analyzes the record of the file name specified by the READ instruction and extracts information for creating a parameter.

  The record name “FILEREC” is set to the leftmost address “PTR01” by the SET instruction, and “FORM00” having the BASED phrase is assigned a structure area from the address.

  Thus, different structures can be used properly from a specific position by using the BASED phrase.

  The program analysis means 11 considers the area constituting the record and identifies the structure of all records while analyzing the SET command.

  The SUBSTRING instruction is an instruction for handling a part of a character string. Therefore, when the value of the item is used as the length of the character string, it is analyzed by assuming that the structure has the format 4 in FIG.

  The above is a brief description of the program shown in FIG. Note that description of general program operations is omitted.

  3 to 5 are flowcharts showing processing flows in the parameter analysis unit 2 and the screen control unit 3 in FIG. Each processing flow will be described in turn.

  FIG. 3 is a flowchart showing a processing flow in the parameter analysis unit 2.

  In the flowchart of FIG. 3, the parameter analysis means 21 reads the parameter of the logical description stored in the storage device 14 (step 31).

  The parameter analysis means 21 analyzes the presence / absence of a parameter specification error in the read logical description parameter (step 32).

  The record structure creation means 22 encodes the parameters of the logical description analyzed by the parameter analysis means 21 (step 33).

  The storage means 23 stores the parameters encoded by the record structure creation means 22 (step 34).

  The above is a flow in which the parameter analysis unit 2 converts logically described parameters into coded parameters. Note that the processing by the parameter analysis unit 2 is not limited to the procedure shown in the present embodiment, and it is only necessary to change at least a logical description parameter to a coded parameter.

  FIG. 4 is a flowchart showing a processing flow in the screen drawing unit 3. FIG. 4 shows a processing flow when the record format is newly created. When the record format has already been created, the processing flow of FIG. 5 is followed.

  In the flowchart of FIG. 4, the record format assembling means 31 reads the encoded parameters stored in the storage device 23 (step 41).

  The record format assembling means 31 assembles a processing table based on the encoded parameters read from the storage device 23 (step 42).

  The display drawing means 32 displays the format on the screen of a display device (not shown) (step 43).

  A user such as a business program programmer can confirm the format displayed on the screen of the display device and can input item data through an input device such as a keyboard according to the screen format. When data that does not match the conditions is input, the display drawing means 32 displays a message prompting re-input as an error on the screen.

  Here, the data acquisition means 33 reads the item data input according to the screen format (step 33).

  When the processing is completed for all formats (Yes in step 45), the flow of FIG. 4 ends.

  If the processing has not been completed for all formats (No in step 45), the screen drawing unit 3 determines whether or not the last item of the record has been processed (step 46).

  If the last item of the record has not been processed (No in step 46), the record format assembling means 31 changes the format (step 47). When the format is changed, the process returns to step 43.

  When the last item of the record has been processed (Yes in step 46), the screen drawing unit 3 registers data in the file registration unit 4 (step 48). When the data registration in the file registration unit 4 is completed, the process returns to step 43.

  The processing in steps 43 to 48 is repeated until the processing is completed for all formats.

  The above is the processing flow of the screen drawing unit 3 when the record format is newly created. Note that the processing of the screen drawing unit 3 shown in FIG. 4 is not limited to the procedure shown in the present embodiment.

  FIG. 5 is a flowchart showing a processing flow in the screen drawing unit 3. FIG. 5 shows a processing flow including a case where the record format is not newly created.

  In FIG. 5, the record format assembling means 31 creates a drawing format (step 51).

  The data insertion unit 34 acquires the data read by the record reading unit 51 from the storage device 42 from the file reading unit 5 (step 52).

  The data insertion means 34 embeds data in each item (step 53).

  The display drawing means 32 displays the format on the screen of a display device (not shown) (step 54).

  A user such as a business program programmer can confirm the format displayed on the screen of the display device and can input item data through an input device such as a keyboard according to the screen format. When data that does not match the conditions is input, the display drawing means 32 displays a message prompting re-input as an error on the screen.

  Here, the data acquisition means 33 reads the item data input according to the screen format (step 55).

  When the processing is completed for all formats (Yes in step 56), the flow of FIG.

  When the processing has not been completed for all formats (No in step 56), the screen drawing unit 3 determines whether or not the last item of the record has been processed (step 57).

  If the last item of the record has not been processed (No in step 57), the record format assembling means 31 changes the format (step 59). When the format is changed, the process returns to step 54.

  When the last item of the record has been processed (Yes in Step 57), the record format assembling means 31 registers data in the file registration unit 4 (Step 58). When the data registration in the file registration unit 4 is completed, the process returns to step 52.

  The processing in steps 52 to 59 is repeated until the processing is completed for all formats.

  The processing flow of the screen drawing unit 3 including the case where the record format is not newly created has been described above. In addition, the process of the screen drawing part 3 shown in FIG. 5 is not limited to the procedure shown in this embodiment.

  As described above, the data creation device according to the embodiment of the present invention reads not only the data entry function but also the data stored in the storage device, and displays the records on the display in units of items according to the conditions indicated by the parameters. can do. In addition, the data creation device according to the embodiment of the present invention has a data update function that enables correction of data.

  According to the data creation device according to the embodiment of the present invention, it is possible to divide records into item units and display them on the display according to the conditions indicated by the parameters. Therefore, both the logic part and the data definition part of the source code can be analyzed. Therefore, according to the embodiment of the present invention, it is possible to create test data even for a record having a complicated format.

(Example)
Examples according to the embodiments of the present invention will be described below. In addition, the following embodiment is an example and does not limit this invention.

  6 to 8 show record formats according to the embodiment of the present invention.

  In general, the record formats handled by business programs can be roughly classified into the following four types.

  Format 1: Fixed format. When the record length is constant and the format is fixed (corresponding to the format 610 in FIG. 6). Records 611 and 612 have a fixed format.

  Format 2: Variable format with record length. When the format differs depending on the length of the record (corresponding to the format 620 in FIG. 6). The record 621, the record 622, and the record 623 have different lengths.

  Format 3: Variable format with fixed position values. In the case of a variable format in which the record length is determined by the fixed position value (corresponding to the format 730 in FIG. 7) The record 731, the record 732, and the record 733 have different lengths except that ITEM01 is fixed.

  Format 4: Format in which items are variable. The item length is variable, and the variable item length is managed by other items (corresponding to the format 740 in FIG. 7). The record 741, the record 742, and the record 743 have the same item name, but there is an item (ITEM03) whose number of digits is managed by a specific item (ITEM02).

  6 to 8, items such as ITEM01 and ITEM02 represent item names, and XXX and X111111111 represent data.

  The above formats 3 and 4 can be created by a general-purpose test data creation tool as long as there is only one in the record. However, when there are a plurality of items of formats 3 and 4, it cannot be handled.

  In the format 5 (format 850) of FIG. 8, an example of the record format after nesting the format 3 and the format 4 as a complicated format is shown. The top record 851 is a record in a simple format.

  In the second record 852 from the top, the value of ITEM01 is AAA and the value of ITEM12 is 111.

  In the third record 853 from the top, the value of ITEM01 is AAA, the value of ITEM12 is 222, and ITEM22 has the length of ITEM23.

  In the bottom record 854, the value of ITEM01 is BBB, ITEM31 has the length of ITEM32, and ITEM33 has the length of ITEM34.

  If the record is of format 5, it will not be clear which format is used unless the program logic is analyzed. Therefore, both the logic part and the data definition part of the source code are analyzed.

  According to the data creation device according to the embodiment of the present invention, it is possible to divide records into item units and display them on the display according to the conditions indicated by the parameters. Therefore, both the logic part and the data definition part of the source code can be analyzed. Therefore, according to the embodiment of the present invention, it is possible to create test data even for a record having a complicated format.

  FIG. 9 is obtained by converting the records 851 to 854 in FIG. 8 into logically described parameters. The parameters of the logical description in FIG. 8 correspond to the contents described in the BASED SECTION in the program source in FIG. This conversion is performed by the parameter creation unit 1.

  The parentheses on the right side of the second row of the parameter 90 are described in the order of item name (ITEM01), attribute (character), number of digits (3), = constant (= 'AAA'), and label (L01). The same applies to the third and tenth stages.

  The parentheses on the right side of the 16th row are described in the order of item name (ITEM22), attribute (number), number of digits (3), and #item name (# ITEM23). The same applies to the 22nd and 24th stages.

  The other levels are described in the order of item name, attribute, and number of digits.

  The parameters of this logical description are created by the parameter creation means 12 and stored in the storage device 14.

  A table 100 in FIG. 10 is a table in which data obtained by encoding logical description parameters stored in the storage device 14 is tabulated.

  In the type column, 0 indicates a fixed format and 1 indicates a variable format.

  In the attribute column, 0 indicates a character, 1 indicates Japanese, and 2 indicates a binary number.

  In the condition column, 0 indicates no condition, 1 indicates a value, and 2 indicates the number of digits.

  Below, the main item numbers are briefly explained.

  Item number 1 is an instruction to change the format according to the format and value of ITEM01.

  Item number 2 is an instruction of only the item format.

  Item number 10 is an instruction to hold the number of digits of ITEM 23 whose value of ITEM 22 is item number 11.

  Item number 11 is an instruction that the maximum number of digits is 50 and the actual number of digits is held in item number 10.

  The number of digits when item number 11 is displayed on the display is the number of digits that item number 10 holds. Reset.

  The above is a brief description of each item number.

  The coded parameters in FIG. 10 are created by the record structure creation means 22 and stored in the storage device 23.

  FIG. 11 is a display example of the screen 110 output from the display drawing 32 of the screen drawing unit 3 of FIG. 1 to a display device (not shown). In the upper part 111 of the screen, the records are divided and displayed for each item. In the lower part 112 of the screen, a list of records is displayed.

  When data is input to a portion where the record in the upper part 111 of the screen is disassembled and displayed for each item, the data acquisition unit 33 reads the input data. The data acquired by the data acquisition unit 33 is converted into a record format by the data registration unit 41 of the file registration unit 4 and stored in the storage device 42.

  The record reading unit 51 reads a record stored in the storage device 42 and sends it to the screen drawing unit 3.

  The record format assembling means 31 searches the encoded data stored in the storage device 23.

  If a condition is specified for the corresponding item, the record format assembling means 31 changes the corresponding format for the subsequent items. The data insertion means 34 divides the record sent from the record reading means 51 based on the information of the encoded data retrieved by the record format assembling means 31, and merges it with the record configuration information. The display drawing means 32 redraws the changed format.

  If data that does not match the condition is input, the display drawing unit 32 displays a message prompting re-input as an error on the screen.

  The display drawing means 32 sequentially displays data assembled as records on the lower screen portion 112.

  In FIG. 11, on the right side of ITEM01, 11, 12, 13, 14 in the upper part 111 of the screen, records in the 00002 line in the lower part 112 of the screen are divided into items and displayed. This corresponds to the procedures on the sixth and seventh lines from the top of the procedure section (PROCEDURE DIVISION) in the source code of FIG.

  Although not shown, when “222” is input to the ITEM 12, items corresponding to “222” are displayed. This procedure corresponds to the procedure on the 9th to 12th lines from the top of the procedure section in the source code of FIG. In the source code of FIG. 2, the same procedure applies to the 13th and subsequent lines from the top of the procedure section.

  Test data is created according to the above flow. In addition, the Example given here is an example for demonstrating this invention, and does not limit this invention.
