importing the test rule file into an automatic test module to generate a rule table;
starting test, namely realizing one-key starting test through QT self-contained signal and slot function design, performing remote control telemetry/timer sub-thread calling according to a normal flow of a rule table by a test execution flow, and performing manual intervention treatment under abnormal test conditions;
the specific process of starting the test is as follows:
starting automatic test software, and automatically reading a rule table by the automatic test software;
identifying a remote control instruction, in particular identifying whether the remote control instruction is a remote control annotating task or a remote measurement interpreting task; if the remote control annotating task is the remote control annotating task, executing a telemetry interpretation task after the remote control annotating task is executed; otherwise, directly executing the telemetry interpretation task;
comparing and analyzing the telemetry result by using the queried telemetry data and the duration of telemetry interpretation to obtain a comparison analysis result;
judging whether the comparison analysis result is true, if so, further judging whether to execute the next rule in the rule table; otherwise, executing an exception handling sub-thread;
when executing the abnormal processing sub-thread, judging whether to continue testing, if so, performing manual remote control of the number of bets, further judging whether the number of bets is completed, and if so, executing a remote control interpretation task; otherwise, the remote control command is re-identified.
9. The generalized satellite semi-physical automation test method of claim 8, wherein the specific process of performing the remote wager task is:
identifying a remote control instruction, further identifying whether a delay note is needed, and if so, identifying delay time and then sending the remote control instruction; otherwise, directly sending a remote control instruction;
judging whether the number of bets is completed after the remote control instruction is sent, and if so, directly executing a telemetry interpretation task; otherwise, re-identifying the remote control instruction;
the specific process for executing the telemetry interpretation task is as follows:
identifying a telemetry channel, then inquiring telemetry data, judging whether delay interpretation is carried out or not at the same time, and if so, continuously interpreting the time length after identifying the delay time; otherwise, directly performing one-time interpretation.
