Abstract

PURPOSE:To automatically detect an abnormal state at the time of operating a program, to collect necessary data and to automatically restart a program by forming a device for collecting information independently of a device for executing a program to be tested. CONSTITUTION:A program to be tested is started and an automatic monitoring program in a supporting device 2 is started by an instruction from a terminal equipment 5. A false call generator 6 generates a false call to be tested in a device 1 to be tested. An automatic monitoring program applies a command for monitoring a state to the device 1 to be tested through an adaptor 3 in a fixed period and decides whether the system is abnormal or not in accordance with the response. When the program to be tested detects abnormality in an abnormal detecting routine, the operation is jumped to a monitor program. The automatic monitoring program monitoring program detects the jump and starts a data collecting program stored in the supporting device 2. The data collecting program capable of detecting abnormality stores all the areas or a necessary part of a program area and a data area in the device 1 to be tested.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a program testing method, and in particular, to a method that enables general-purpose and automatic collection of test information when an abnormality occurs during a program test. It is something.

[Conventional technology]

When creating a program, it is necessary to test whether it works properly.

Conventionally, when testing a program, when an abnormality occurs, the program is stopped, a monitor program is started, the necessary data is output to a printer, a line printer, or a magnetic tape, and the test is repeated after the output.

For example, as shown in FIG. 3, a routine for checking abnormal operation is embedded in the program, and when an abnormal operation is detected, the program jumps to a monitor program. The monitor program outputs a message indicating that it has been started to the tights writer. Here, the examiner uses a typewriter.
Inputs a data output command and outputs the data necessary to analyze the cause of abnormal operation to a typewriter, line printer, magnetic tape, etc. Once the output is finished.

Run the test again under the same or different conditions.

[Problem that the invention seeks to solve]

However, such a test method has the following problems.

(1) The tester must always monitor the startup of the monitor program.

(2) The tester must output the data.

For this reason, necessary data may be forgotten due to a procedural error or the like.

(3) Data output takes time. For this reason, we try to output the necessary data as much as possible, but on the contrary, we end up omitting necessary data. It takes some skill to get used to rounding up data and debugging, and it takes some time to get used to it.

In the case of (2J # (3) above, it takes time to run the test again, and in some cases, the same abnormality may not occur.

Outputting to magnetic tape takes less time, but it still takes time to output because it has to be output in a visible form to another device.

[Means for solving problems]

A program testing method according to the present invention includes a first means for stopping operation and starting a monitor program when a program under test executes an abnormal operation, and a first means for starting a monitor program when a program under test executes an abnormal operation; a second means for detecting whether or not the program under test is operating normally; and a second means for transferring the program under test and data area to an external storage device when an abnormality is detected by the second means. a fourth means for storing the program under test and the data area by the third means in an external storage device; and a fourth means for executing a command to the monitor program to restart the program under test. It is characterized by having the following means.

[Effect]

Summary 1 In order to solve the above-mentioned problems, the present invention has the following features:
This method provides a program testing method that can automatically collect test result data in a short period of time. Detects abnormal conditions during execution, automatically collects necessary data, and automatically restarts the program.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure shows an example of application of the program testing method according to the present invention. 1 is a device under test that runs the program under test; 2 is a support device that supports the test; 3 is an adapter that transfers data between the device under test and the support device; 4 is a storage device; and 5 is a support device. The terminal device 6 of the device is a pseudo call generating device.

When testing a program, first start the monitor zologram on the device under test 1, and then follow the instructions from the terminal device 5).
The storage device 4 is loaded by the load program in the support device 2.
The program under test stored in the program under test is loaded into the device under test via the adapter 3. Next, the program under test is started, and an automatic monitoring program in the support device 2 is started according to an instruction from the terminal device 5. Then, the pseudo call generating device 6 generates a pseudo call to be tested to the device under test ft1. The automatic monitoring program inputs a status monitoring command to the device under test 1 via the adapter 3 at regular intervals, and based on the response, determines whether or not the system is abnormal. If the program under test detects an abnormality in the abnormality detection routine, it jumps to the monitor program. The automatic monitoring program detects this and activates the data collection program in support device R2. As an example of detection, if you use the DMP J command, which can be used in the program under test but cannot be used in the monitor program, the response will be returned normally in the program under test, but in the case of an error, the monitor program will not work. Therefore, the response is not an error, and a data collection program capable of detecting an abnormality stores the entire program area or a necessary part of the program area and data area of the device under test in the storage device 4 via the adapter 3. When the storage is completed, the information collection program inputs a command to the device under test to restart the program under test and also starts the automatic monitoring program of the support device.A summary of these operations is shown in FIG.

[Explanation of effects]

As explained above, according to the present invention, K can automatically collect all necessary programs and data areas without the need for constant monitoring by the tester, and when an abnormal operation is detected in the program under test. Because of this, you don't have to forget to collect data, and because the test can be automatically executed as many times as you like, you can do the initial preparations at night, for example, and then leave the rest unattended, allowing you to effectively utilize the equipment under test. I can do it. Furthermore, since the collected data is stored in the storage device of the support device (for example, a minicomputer), even beginners can easily perform the Shibubug work by creating various support programs in the support device.
