Hi em,
I understand that you want a way to verify the external function called and the parameters passed to it, in Simulink Test.
Although the MATLAB Mock library is primarily intended for MATLAB functions, you can still use it to mock the external function and verify its calls through MATLAB Function Block. You can refer to the following documentation for more details on MATLAB function block: https://in.mathworks.com/help/simulink/ug/what-is-a-matlab-function-block.html
Here's how you can do it:
- Create a MATLAB function that wraps the external function you want to test. Let's call it myExternalFunctionWrapper. This function takes the same inputs as the external function and calls it internally.
- In your Simulink model, replace the S-Function block that calls the external function with a MATLAB Function block. Inside this block, call the "myExternalFunctionWrapper" function instead.
- In your Simulink Test test case, you can use the MATLAB Mock library to mock the "myExternalFunctionWrapper" function. This allows you to verify if it was called with the expected parameters.
Hope this workaround helps.
