Send an instruction to.

In such a state, in the reproduction test necessary for investigating the cause when a failure occurs, the tester retrieves the executed procedure from the check sheet or the command history of the tester, and again the almost same result is obtained. You are rerunning the procedure.

Therefore, the reproduction test requires the same condition setting as when the phenomenon occurs. In order to execute such a faithful reproduction test, it is necessary not only to re-execute the same pseudo-instruction but also to execute the same procedure including the timing.

When a single test procedure manual is being executed, it is only necessary to re-execute the procedure manual. However, in debugging an electronic exchange, such a simple case is rare and the tester The mainstream is the asynchronous command input from the console, the test by multiple procedures, and the test by the combination of them. When reproducing such a complicated procedure, it is very difficult to perform a faithful reproduction test including the execution timing.

As a result, there is a drawback in that, when a failure occurs during the operation test of the electronic exchange, the retest cannot faithfully reproduce the condition and procedure when the phenomenon occurs.
