ECU test modify test case

In the use of ECU TEST When software is tested automatically , Due to lack of previous testing experience , It is often impossible to test a function completely . For example, the function of switching lights . When the light is on , The relevant signals returned by the controller to the bus are 1, When the light is turned off, the relevant signal is 2, At the same time, the controller has a hard line to output signals to the board . Early test engineers only focus on message interaction and ignore hard line detection , Therefore, develop relevant scripts to add hard wire detection signals at specific locations of the original cases , Ensure that the hardwire signal is detected every time the message value is read , Other functions can also be used .
Correlation function / The explanation of class has been pointed out in previous articles , You can read it yourself .
