Is there a recommended way of creating mock functions using cmake-init?

[Kyr27]

Hello! I’m currently testing my C library using the Unity testing framework and cmake-init, and everything has gone smoothly so far. However, I’ve reached a point where I need to mock some Windows-specific functions, such as PostMessage, to get my tests to pass successfully.

Given how amazing this CMake initializer is, I have a question: Is there a recommended way to mock functions using cmake-init? If possible, could you provide an example?

Thank you!

You don't "mock functions using cmake-init". You can just use regular old dependency injection and not hardcode the use of PostMessage, but that's just one way of dealing with making software testable.

Thank you for your fast response.
I appreciate the suggestion about dependency injection. I’m already using it in my setup, so I should have been clearer in my question. What I meant by "mock functions using cmake-init" was to ask if cmake-init has a recommended approach or an opinion for handling function mocking, given how opinionated it is in other areas.

I’ll take your answer as a "no" and continue with my current dependency injection setup. Thanks once again.
