Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a simulation test method for input devices, and in particular, in the development of a program that inputs data from an input device, it is an input device that performs a test under a situation where the input device is not ready. This article relates to a simulation test method for equipment.

[Conventional technology]

Conventionally, in a program test in which data is input from an input device, even if a simulation is performed, a simulation method is used in which the contents of the test data are reported as they are.

[Problem to be solved by the invention]

In the conventional input information simulation test method described above, a corresponding hardware environment had to be prepared. In many cases, program development proceeds without depending on the preparation of the hardware environment, and the problem arises that the hardware environment is not prepared at the program testing stage, which has the disadvantage of delaying the test implementation time.

Furthermore, even if the relevant hardware is in place, there are cases where it is impossible to actually generate an abnormality in abnormality processing tests, and there are cases where Test 1 is impossible.

[Means to solve the problem]

The input/output device simulation test method according to the present invention includes test program replacement means for replacing the part read from the input device with input device simulation processing when testing a program to be executed by inputting various data from the input device. , a test data input means for creating input data in advance and inputting it into the test program at the time of testing, and editing the input test data file based on the device information file to make it appear as if it was input from the input device. and test data editing means.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of this embodiment. The block diagram shows the entire relationship between three processes and two files that make up the input device simulation test method. The device information file 11 and the test data file 12 are created by existing file creation means, and an example of the file contents is the device information file 21 in FIG. 2(a) and the test in FIG. 2(b). Shown in Cheetah File 22. Here, as an example of the device information file, the one shown for magnetic tape or the device information file 2
3, so this will be explained. The device name 24 should have the meaning of a file heading, and the device 25 should have an abbreviation (here, the device name, magnetic tape, device symbol, or 000) should be entered.
1). For the number of elements 26, enter the number of types of elements necessary to configure the data of the applicable device, and then enter the number of elements next (1...record length, 2...block length, 3...data format,······).

The test data file 22 stores data one by one in a sequential format. By preparing in advance in this manner, a simulation test of the input device of the present invention can be executed. As shown in the block diagram of FIG. 1, this simulation test includes a test program replacement means 13 that replaces the part read from the input device in the test program with input device simulation processing, and a test that reads test data from the test cheat file 12. It consists of three blocks: a data input means 14 and finally a test data editing means 15.

FIG. 3 shows the process replacement part in the test program replacement means 13. This is on test program 31,
The reading processing part 32 from the input device is executed by the simulator 3.
4, and the other part 33 is not touched at all.

FIG. 4 shows details of the test data input means 14 for reading test data into the simulator from the test data file 12. The test data input means 14 uses the method generally used as the sequential file reading process 42 as is. To put it simply, this is a method of reading one data item at a time until there is no more data in the test data file 12.

Next, the processing of test data editing means]5 is shown in FIG. Data related to device information from the device information file 11 is input in device information input processing 51 . Based on that information,
Simulation data from the input device is completed by performing a test data editing process 52 that edits the test data that has been previously input. Then, in order to ensure consistency with the test program, test program consistency processing 5
Do step 3.

Further, a flowchart of the device information input processing 51 is shown in FIG. Perform input processing 61 from the device information file, compare the device type to be tested (given by the replaced input device simulation process 35) and the information in the device information file 11 (reference numeral 62), and find the corresponding file. Search for it.

Here, the processing contents of the test data editing process 52 will be explained with reference to the flowchart shown in FIG. First, the device type is determined 71, and magnetic tape editing processing 72. ID cart editing processing 7 is performed.
3. A processing means such as barcode editing processing 74 is provided for each device to perform corresponding editing processing. Taking the magnetic tape shown in FIG. 2(C) as an example, a simulated data type (simulated data type 28) is created from the data of the device information file. And test data file 2
Set the test data input from step 2. This completes the simulation data. Thereafter, by performing the test program matching process 53 shown in FIG. 9, the simulation data is completely edited. The device type is as shown in Figure 8 (for example, ID card,
(magnetic cards, paper tape, keyboards, magnetic tape, barcodes, fax machines, tablets, optical character readers, etc.).

Furthermore, the flowchart of the test program matching process 53 is shown in the ninth section.
As shown in the figure. Since the test program is in a format in which target data is stored in a certain area, a transfer format creation process 91 to the test program is executed to create the format. Next, a data format change process 92 is performed to change the format of the test data to match the format just created, and the process ends. Finally, the test program matching process is returned and the process ends.

〔Effect of the invention〕

As explained above, the present invention has the unprecedented effect of being able to perform tests regardless of the presence or absence of hardware by providing a test program replacement means, and since it can simulate the data of the input device, it can be used to convert various input data. There is an effect that it becomes possible to test the case.
