Embodiments of the data processing test apparatus according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows the configuration of the embodiment of the data processing test apparatus. In this example, the data processing device related to the test target is the application 10. As shown in FIG. 19, this application 10 executes an operation of determining whether or not the input data matches given data specification information. That is, the application 10 is given the specification information about the input data. For example, it is assumed that the specification information "number of 4 digits or less" is given to the "product name code". Then, when "123456" is input from the keyboard of the workstation or the like in which the application 10 is incorporated (14
1) This is accepted by the OS (operating system), and the above "" is entered in the input field of the product name code that was set on the screen of the workstation etc. earlier than this.
"123456" is displayed together with the title display of "Product name code" (142). When the Enter key is operated (143), this is accepted by the OS and the application 10 is started. , "123456" matches the given data specification information, the validity is determined. Here, the specification information of "5 digits or less" is given, and the input data Is judged to be invalid because it is a 6-digit number (144), so the application requests the OS to display the data in the input field for the product name code in reverse video, and this causes the title of the "product name code" to be displayed. The above-mentioned "123456" displayed in the input field together with the display is highlighted (145).

Following the above, from the keyboard "123"
Is input (146), this is accepted by the OS (operating system), and the above "123" is displayed in the product name code input field together with the title display of "product name code" (147). So, enter (Ente
When the r) key is operated (148), this is accepted by the OS and the application 10 is started. In this application 10, the validity of whether or not "123" matches the given data specification information is determined. Here, since the specification information "five or less digits" is given and the input data is a three digit number, it is determined to be valid (149). Therefore, the application issues a processing request to the OS to display the data of the input field of the product name code as it is. As a result, the above "123456" displayed in the input field is displayed as it is along with the title display of the "product name code". (150). Hereinafter, the validity of the input data is similarly determined.

For such an application 10,

The input simulation means 5 supplies the test data 4 created by the creation control means 1 to the application 10 to execute the processing operation. The monitor 6 retrieves the processing result of the application 10 corresponding to the test data 4. The evaluation means 7 evaluates the suitability of the processing of the application 10 based on the processing result extracted by the monitor means 6 and the test data 4 related to the processing, and the display means 8
Display on B and 9.

When the data specification information 3 is given to the creation control means 1, the validity determining means 11 for determining whether or not there is a contradiction between the information of the data specifications, and the validity determining means 11, When it is detected that there is a contradiction between the information of the data specifications, the display control means 13 that causes the display means 8A to display the information including the contradiction and the normal data that conforms to the specification based on the data specification information 1. And the data creating means 12 for creating the test data 4 composed of the abnormal data that do not match.

The evaluation means 7 evaluates the suitability of the processing for each of the test data 4 based on the processing result extracted by the monitor means 6 and the corresponding test data 4, and when the processing is unsuitable. Is provided with an individual determination means 71 for determining the cause thereof, and a display control means 73 for displaying on the display means 8A the cause related to the determination when the evaluation and processing by the individual determination means 71 are inappropriate.

Further, the evaluation means 7 includes an application 10 according to the evaluation based on the individual test data by the individual determination means 71 and the processing result extracted by the monitor means 6.
Comprehensive judgment means 72 for judging whether or not
Display control means 73 is provided for displaying on the display means 8B and 9 the information relating to the evaluation according to each test data by 1 and the determination result by the comprehensive determination means 72. In addition,
The trigger for the input simulation means 5 to operate to activate the application 10 is based on an instruction from a keyboard input device (not shown).

The data processing test apparatus constructed by the above means is realized by a terminal such as a workstation having each section as shown in FIG. Processor 3
1, a main memory 32 is connected, and the processor 31 functions as each unit shown in FIG. 1 by using the program and data in the main memory 32. Interfaces 34 to 38 are connected to the processor 31 via a bus 33. A keyboard input device 41 used for inputting data is connected to the interface 34, a CRT display device 42 for displaying data is connected to the interface 35, and a printout is connected to the interface 36. A printer device 43 is connected. Further, a floppy disk device (FDD) 44 is connected to the interface 37, and a hard disk device (HDD) 45 is connected to the interface 38. The main memory 32 has an OS 21, various drivers (keyboard driver, display driver, etc.) 2
2, application 10 to be tested, test program 2 for realizing the data processing test apparatus according to the present embodiment
3. Other programs and data are provided. The keys of the keyboard input device 41 include various character keys, function keys, enter keys, cursor movement keys, and the like.

The data processing test apparatus according to the above configuration is
It operates as each unit and each unit shown in FIG. Each of these means and each section shows the function realized in the workstation 30. The data specification information of the specifications 2-2 to be input to the data processing test device is created by the operator 40 using the personal computer 20, for example, so as to be input to the computer.
At this time, the personal computer 20 constitutes the specification creating unit 2-1. The specification information has one or more items, and each item is identified by a unique item number.
The specification information is specified by specifying the "type" and the "value".

The designation of "type" is as shown in FIG.
The character type is M and the data length is B bytes. The character type is “N” as shown in FIG.
One of "X", "9", and "99V99" indicates the meaning shown in FIG. As shown in FIG. 5, the designation of “value” includes selection designation and range designation. In the case of selection designation, it indicates that one of the values within the curly brackets has been designated, and in the case of range designation Indicates the corresponding meaning in the figure by the description as indicated by the symbols in FIG. FIG. 6 shows an example of a specification document created according to the above rules. The meaning of the information of the specification of FIG. 6 is shown in FIG. The information related to the specifications created in this way is stored in a file, for example, on a floppy disk or a hardware disk, and input to a data processing test device.

The creation control means 1 of the data processing test apparatus is
The data specification information of the specification 2-1 is received, and the specification check unit 2-3 equivalent to the validity determining means 11 of FIG. 1 determines the validity of the specification information. That is, "type" and "value"
Check if and are not inconsistent. For example, in item number 1 in FIG. 6, when 10-byte data is designated, but a 2-digit alphabet is designated in the value designation, there is a contradiction. In this way, it is judged whether the elements of the selection designation, the upper limit value and the lower limit value of the range designation are consistent with the "type" related to the designation, and if there is a conflict, the fact that there is a conflict and its item number are indicated. The display is executed by the display control unit 2-22 on the CRT display device.

The data processing test apparatus described above executes a program by executing a program according to the flowchart shown in FIG. That is, the data processing test apparatus monitors the input (51), and if there is the input, it judges whether the data specification information of the specification is input, the test start instruction, or the screen design. Here, the test data is created when the data specification information is input (53), the test process is performed when the test start instruction is given (54), and the screen design process is performed in the case of the screen design. Is executed (55). The operation will be described below in the order of screen planning, test data creation, and test processing.

When the screen design is instructed, the process proceeds to the screen design process (55), but the operation of the flowchart shown in FIG. 9 is executed here. First, an announcement is displayed as to whether the screen design is newly made or the existing screen is changed (56). Next, the response input from the keyboard input device is analyzed to detect whether it is a new screen design (57). Here, when there is a response indicating that it is new, the item number is reset (58), the item number is incremented by "1" (59), and an announcement display prompting the input of the data name is displayed (61). Next, it is detected whether or not there is an input of a data name (62), and when there is an input, this data name is displayed and stored on the CRT display device as shown in "Name" of FIG. An announcement display prompting the user to enter the start coordinates of the input field is displayed (63). Following this announcement display, the presence or absence of input is detected (64), and when there is an input, the start coordinate related to the input is displayed and stored as a dot on the CRT display device, and further the announcement display prompting the input of the end coordinate of the data field. (65). Following this announcement display, the presence or absence of input is detected (66), and when there is input, a field is displayed on the CRT display device as shown in FIG. 10 and the ending coordinates relating to the input are stored, and the input of screen design is completed. Announcement prompts you to enter whether to continue (6
7). Next, it is detected whether or not it is an end input (68), and when it is a continuation, the item number is incremented by "1" (59), and the operations after step 61 are further continued. In this way, when a series of screen designs is completed and an end input is made, the file name input is received (68) and stored as a file and restored. At this time, all the items shown in FIG. 10 are input, and the stored file is stored as tabulated data as shown in FIG.

On the other hand, as described above, if a request is made to change the data relating to the filed screen design, an announcement prompting the input of the file name is made (80), and the input is waited (81). Then, the corresponding file is called and displayed on the CRT display device as shown in FIG. 10 (82). Next, an announcement display prompting the user to specify the item number related to the change is displayed (83), and the input is awaited (8).
4). When there is an input, the item number is set as the designated number, and the operations from step 61 to step 67 indicated by the broken line 60 are performed. After this, it is detected whether or not the input is the end (86), and when it is the continuation, the operation from step 83 is repeated again. In this way, when a series of screen design changes are completed and an end input is made, the input of the file name is received (86) and the file is stored and restored. In this embodiment, the data field is input and output numerically, but in other embodiments, the data field is designated by moving the cursor to the start coordinate and the end coordinate and inputting the confirmation. With this method, the data field can be designed as in the embodiment.

Further, in the flow chart of FIG. 8, when the process proceeds to the creation of test data (53), the operation is performed for each item number by the program of the flow chart of FIGS. That is, since the specification information according to the specification as shown in FIG. 6 is input, it is determined whether or not a value is specified based on the specification information when creating the normal data shown in FIG. (101), if the value is not specified (example of item number 1 in FIG. 6), the character type of the specification information is referred to and the corresponding character type is selected from the corresponding character data based on the random number data provided in advance. The operation of extracting the number of pieces of data corresponding to the data length of the specification information and using this as one piece of test data is performed N times (where N is
It is set as the number of data to be created. )repetition,
After obtaining N normal data (102), the data is saved and restored (103). On the other hand, when it is detected in step 101 that a value has been designated, it is detected whether the range is designated (selection designated) (104). If a plurality of ranges are designated, the range is divided into N + 1 and the divided data is divided into data (105). Next, with respect to the data thus selected, N pieces of data are sampled based on random number data provided in advance to obtain N pieces of data (10
6, 103). If the range does not include N data, all are selected (106). If only selection is designated, N pieces of data are selected from the data relating to selection (106). In this way, when N pieces of normal data are obtained for one item number, this data is saved and restored, and if the test data of another item number has not been created, the program of the same flowchart is used. Create test data by.

Following the creation of normal data, creation of abnormal data is executed according to the flowchart of FIG. That is, since the specification information according to the specification as shown in FIG. 6 is input, whether or not the character type is specified for item number 1 is determined based on the specification information (107), and the type is specified. If not (example of item number 1 in FIG. 6), it is detected whether or not a value is specified from the specification information (108). Again, if no value is specified, any data other than the data length may be used, so an appropriate character type (plurality may be used) is selected (10
9) Referring to the data length of the specification information, continuously create data of a predetermined data length contrary to the data length, select N pieces using random numbers (110), stock and restore. If there are other item numbers after restoration, please refer to Step 1
The operation is executed from 07. On the other hand, when it is detected that there is a value designation in step 108, it is next judged whether it is a range designation or a selection designation (111), and if it is a range designation, a character type is inferred from this range designation data, Data other than the character type and having a specified data length of not less than the upper limit value +1 and not more than the lower limit value -1 are continuously created, and N pieces are selected using a random number (112) and stocked. Restore. In the case of selection designation, the character type is inferred from the selection designation data, data other than the character type and having a designated data length that is not designated is continuously created, and N pieces are generated using random numbers. Is selected (113) to stock and restore.

On the other hand, when the character type is designated, it is detected from the specification information whether or not the value is designated (117).
Here again, if no value is designated, data having a designated data length other than the designated character type is continuously created, N pieces are selected using a random number (118), and stocked and restored. . On the other hand, when it is detected that there is a value designation in step 117, it is next judged whether it is a range designation or a selection designation (114). Data having a value of +1 or more and data having a specified data length of not more than the lower limit of -1 are continuously created, N pieces are selected using a random number (115), and stocked and restored. Further, in the case of selection designation, data having a designated data length which is not designated and which is not designated is continuously created, and N pieces are selected using a random number (116) and stocked. To recover. In any case, if there is another item number after the restoration, the operation is executed from step 107 for this. Thus, N pieces of abnormal data are created for each item number. FIG. 14 shows a part of the example of the test data created as described above. Here, the data length error test data is not created except for step 110, but in another embodiment, a fraction of the data length error data is included in the N test data. Include. By doing so, the test data can be created more comprehensively. FIG. 15 shows a part of an example of abnormal data relating to a data length error created in this way.

When the screen is designed and the test data is created as described above, the data processor can be tested. That is, as shown in FIG. 3, when the data of the screen information table 2-5 and the test data 2-7 are given to the input simulation means 5, the test starts. The input simulating means 5 selects the test data corresponding to one item number of the test data, and the cursor moving unit 2-9 executes the cursor movement input to the corresponding field of the screen. That is, the OS 2-11 is in a state of waiting for input of data in the data field. Therefore, it is judged whether the application 2-12 is normal or abnormal with respect to the first test data of the item number, and if it is normal, the display is reversed, and if abnormal, the input field is set to a state where the display is not reversed.
Input the test data. Then, the data input unit 2-8 sends the test data to the OS 2-11, the input corresponding to the operation of the enter key is sent, and the input via the keyboard driver 2-10 is simulated.

Then, the OS 2-11 starts the application 2-12 to be tested. Then, the application 2-12 judges the suitability based on the specification information of the input data which is set previously for the simulated input test data, and if it is correct, displays the input field as it is. If it is incorrect, an instruction to reverse the display of the input field is output. Originally, this output is fetched from the OS 2-11 to the display driver 2-13 via the determination monitor unit 2-14 and used for display control, but here it is passed to the evaluation means 7. In the test judging section 2-15 of the evaluation means 7, the test data 2-7
On the basis of normality or abnormality of the test data, which is an expected value, the success or failure of the determination of the application 2-11 is determined and the result is displayed as a message on the CRT display device via the display control means 2-20. Such simulated input of test data is successively made, the result is sent to the comprehensive test judging unit 2-17, and finally the suitability of the application 2-11 is judged, and the test result 2-18 is displayed. It is output to the CRT display device or the printer device via the control means 2-21.

The test processing operation described above is executed by the program of the flowchart shown in FIG. 16 when a test instruction is issued in the flowchart of FIG.
First, the screen information and the file name of the test data are imported (120), the file of the screen information and the test data corresponding to the input of the development engineer is opened, and the item number and the data No (number) are set. The item number is reset and the item number is set to "1" (121). Next, the data number is incremented by "1" (122), and the coordinate information in the input field corresponding to the data name corresponding to the item number (here, corresponding to "1") is input to the OS (123). ). Further, based on whether the test data of item number "1" and data No. "1" is abnormal or normal, the display state is set opposite to the originally expected display state (124), and the corresponding test data is set to the OS. (125), and enter the operation data of the enter key in a simulated manner (126). Then, the OS starts an application program which is a data processing device,
Determine the suitability of the data.

The judgment result is monitored and fetched (12
7) Then, the suitability of the judgment of the application program is judged by comparing with the expected value, and it is displayed on the CRT display device (128). That is, in step 124, the display state is set opposite to the originally expected display state. Therefore, if the determination of the application program is proper, an instruction to invert the display should be output. . Therefore, it is detected whether or not an instruction to invert is issued, and the result is displayed as shown in FIG. In the example of FIG. 17, since it should be determined that the result is “correct” (corresponding to “result”), the determination is “not”, the determination is inappropriate, the cause is displayed, and Furthermore, an announcement is displayed as to whether or not the test will be continued. In the above, in creating the test data, especially when creating the abnormal data, the nature of the created test data is known,
In other words, it is known whether the data length is abnormal, the character type is abnormal, the range is abnormal, and how much the abnormality has occurred, and the algorithm for creating each test data is stored. Therefore, in the above, when the determination of the data processing device is inappropriate, the cause is analyzed and displayed by the algorithm for creating the corresponding test data. In the example of FIG. 17, the item number is “1” and the data number is “5”.

As described above, it is detected whether or not the continuous input instruction is given from the development engineer (129), and if there is a continuous input response, it is detected whether or not the data No. is ended (13).
0), if not completed, proceed to step 122 and data No.
Is incremented by "1" and the following processing is executed. In this way, when the judgment by the simulated input is completed for the test data of all the data Nos. For one item number, the process proceeds from step 130 to 131, it is detected whether the item number is completed, and if there is another item number, the item is judged. The number is incremented by "1" (132), and the processing after step 122 is continued. In this manner, the test data of all the data Nos of all the item numbers are simulated input, and when the individual judgments are completed, the comprehensive judgment of whether or not the application program is acceptable is executed in step 133. As the determination result, as shown in FIG. 18, the result is displayed for the test data of all the data Nos of all the item numbers, and the comprehensive determination result is displayed in the bottom column (134). The data related to this result is printed out from the printer device (135).

In the above embodiment, the comprehensive judgment result is automatically printed out, but in other embodiments, it is printed out according to the instruction of the development engineer. As a result, the comprehensive judgment result listed can be obtained when necessary. Further, in the embodiment, an example is shown in which input is made to the OS and the OS starts the application by the enter key. However, in another embodiment, data of a type in which the application has already been started at the time of inputting data. The present invention is applied to a processing device (application). Even in this case, an accurate test is performed by the comprehensive test data as in the present embodiment.

The data specifications are various, and the present invention can be applied to data having two or more items. For example, the first item is any of (1,0), the second item is any of (1,2,3) when the first item is "0", and the first item is Item is "1"
The specification, which is either (4,5,6) when the first item of possible values (1,0) and possible values of the second item (1, 2, 3, Normal data and abnormal data are created from the combination with 4, 5, 6) and used as test data. In this way, comprehensive test data is created and appropriate tests are performed.

[0039]

As described above, according to the present invention, the test data composed of the normal data conforming to the specification and the abnormal data not conforming to the specification is automatically created based on the specification information, and this test is performed. Since the creation of the test data and the evaluation of the test target data processing device are performed, an appropriate test with no leakage is performed as compared with the case of manual operation.
