Add function that verifies that all when mocks are called

Inspired by verifyAllWhenMocksCalled of jest-when.

Thanks @mcous for your fast response and the interesting feedback!

Those are the use cases, why we do call verifyAllWhenMocksCalled() in a global afterEach hook in our project:

• We want to know if our application, for whatever reason, didn't do the calls that we mock (and therefore expect) in our tests. During refactoring for example.
• We want to have a minimal test setup. The verification helps us, especially when copy-pasting a complex test setup, to get rid of unnecessary mocks.

I agree with you, that a wrong implementation of the application should end in a red test because of a unfulfilled expectation. But it is very helpful to get a pointer, to why the output differs from the expected result.

So I think that function will provide a further possibility to verify that the application does work as expected and improves the development workflow.

@BeniRupp did you have any additional thoughts after my comments/review above? If not, I think I’m going to close this PR due to misalignment with project goals.

Regardless, I’m very happy to continue this conversation about more debugging capabilities!

Hi @mcous, sorry, I did not find the time to work on that issue. So I have no additional ideas at the moment and it's fine for me to close this PR.

I let you know if I can figure out another debugging idea. 👍
