Handling asserts

[Wilmer Suarez]

Is there any way, using unity and/or cmock, to handle when asserts occur within the code under test? E.g., passing in a null pointer to an assert check.

I believe I saw a PR recently for handling this natively in unity. I don't believe it's been merged yet.

CMock can definitely mock assert as a function, but instead of #include <assert.h> directly, you'd have to create a wrapper header. It could be as simple as this:

// assertion_api.h

#ifdef TEST

void assert(int);

#else

#include <assert.h>

#endif

Then you would include assertion_api.h anywhere that you would normally include assert.h

The assert "function" could then be used like so:

assert_Expect(0); // expecting assertion to be false

assert_Expect(1); // expecting assertion to be true

It's not perfect, but it'd work.

Down the road, we plan to have ceedling automatically take care of mocking this for you and giving access to these expectations.

I hope this helps.
