[0002]

2. Description of the Related Art A simulated test method for this type of stored program controlled electronic exchange is disclosed, for example, in Japanese Patent Laid-Open No. 7-2501.
As disclosed in Japanese Unexamined Patent Publication No. 59-59, a simulation result based on the simulation target data is output to a CRT and a file from a call control signal received from an electronic exchange or a terminal operation input from a keyboard or a mouse.

FIG. 5 is a basic configuration diagram of a simulation system in a storage control program-controlled electronic exchange to which no communication path system device is connected. Firmware 402
Captures the signal output from the software 403 of the electronic exchange 401 to the communication path device, and
Workstation 4 connected to electronic exchange 401 at
04 using the data transfer function of the GP-IB 407, and from the workstation 404 to the GP-IB
407 has a function of transferring a signal received using the data transfer function to the software 403 of the electronic exchange 401.

The simulation system 410 has a communication path system simulation means 411, a CRT output means 412, and internal data 413, and operates on a workstation 404. The workstation 404 has a keyboard 40
When receiving a call control signal transmitted from the firmware 402 of the electronic exchange 401, the communication path system simulating means 411 attached with the mouse 5, the mouse 406, and the CRT 408 analyzes the call control signal with reference to the internal data 413.
A response signal is generated, transmitted to the firmware 402 of the exchange 401 connected by the GP-IB 407, and
The simulation result is graphically displayed on the CRT 408 of the workstation 404 via the T output means 412. The keyboard 40 of the workstation 404
5 or the input from the mouse 406, the communication path system simulation means 411 generates a response signal corresponding to the input, and
The information is transmitted to the firmware 402 of the exchange 401 connected by the P-IB 407, and is graphically displayed on the CRT 408 of the workstation 404 via the CRT output means 412.

FIG. 6 is a diagram for explaining the operation of the exchange software in the automatic test method.

Prior to the start of the automatic test of the exchange software, the test executor executes a command 502 of the call processing simulation program, a command 503 of the common signal simulation program, and a command of the control console simulation program in accordance with a series of test procedures. 505 and a command 504 of the terminal simulation program are described to create a command file 501.

When the automatic test of the exchange software is started, the command file separation program 510 determines the type of command by sequentially analyzing each command described in the command file 501, and converts each command into a corresponding call processing simulation program. Command file 515,
These are stored in the command file 516 of the common line signal simulation program, the command file 517 of the control console simulation program, and the command file 518 of the terminal simulation program, respectively.

Thereafter, a call processing simulation program 5
11, a common channel signal simulation program 512, a control console simulation program 513, and a terminal simulation program 514 are a command file 515 of a call processing simulator program, a command file 516 of a common channel signal simulation program, and a control console simulation program. Is automatically operated by the command file 517 of the terminal and the command file 518 of the terminal simulation program.

[0009]

The first problem is that when the simulation result is checked by the simulation test method, the movement of the graphic of the terminal or the exchange including the telephone displayed on the CRT at the time of executing the simulation. After confirming in step (1), only the huge hexadecimal string (hexadecimal display) and comments output to the file are analyzed, and the graphically displayed figure cannot be displayed again.

The reason is that the operation of the simulator inputs the data to be simulated and simulates with the input data. However, after the simulator is executed, the input data is discarded as it is.

A second problem is that when performing an automatic test by the automatic test method, the test executor must manually create one command file according to a series of test procedures.

[0012] The reason is that there is no means for reusing the test procedure of the test once performed manually.

[0013] An object of the present invention is to solve the above-mentioned problems, and to perform a simulation test in a state where an electronic exchange is connected via GP-IB, and then in a state where the electronic exchange is not connected. In addition, it is possible to redisplay the result of the previously performed simulation on the screen, and to perform the resimulation in the previously performed simulation procedure with the electronic exchange connected.

01 (steps 608, 612).

Input information commanding unit 1 waiting for input
16 is in the automatic processing mode, and passes control to the command file analysis unit 114 to execute the next processing. The command file analysis unit 114 extracts the command 303 and the command 302 from the command file list 301 of the command file 115 and transmits the command 303 and the command 302 to the communication path system simulation unit 111.

Further, since the command file analysis unit 114 is in the reprocessing mode, it does nothing even if the command 304 and the command 305 are taken out.

Thus, the command file list 3
01, and when there are no more commands to be reprocessed, the reprocessing mode is reset and the process is terminated (steps 605, 606, 610, 611, 613,
614).

In the above description, the command file is described as having the command file on the disk.
DD, MT, etc.) or memory.

As described above, when the same processing is performed, the command is taken out from the command file and the simulation processing (or the test processing) is automatically performed. No need to do.

When it is desired to realize the same processing as before without connecting the electronic exchange, the call control information is read from the command file, and the simulation processing can be performed. Therefore, the electronic exchange can be easily redone as many times as desired, and the contents of the simulation can be evaluated.

For example, the command file is stored in the FD
If you copy it to a medium such as D, you can use it on a personal computer, so you do not need to prepare many electronic exchanges, meaning that you can evaluate separately by a unit that analyzes simulations in parallel and a unit that performs tests. I do. Therefore, the evaluation can be performed on a personal computer, so that the test quality is improved and the test efficiency is promoted.

That is, it is possible to reuse the simulation result once performed, so that the test quality of the software of the electronic exchange is improved, the test is made more efficient, and the productivity of the software is improved.

[0089]

The first effect is that when the software of the stored program controlled exchange is tested, the electronic exchange uses a command file created when manually simulated once while the electronic exchange is connected. It can be re-executed without being connected. This facilitates verification of the simulation result and improves test quality.

The reason is that it is possible to repeatedly check the visually displayed figure.

A second effect is that the software of the stored program control electronic exchange can be easily re-tested. This makes testing more efficient and improves software productivity.

The reason is that the procedure can be re-executed as it is by a command file created when manually simulating once.
