control when suspending functions emit - is this possible?

[ZakTaccardi]

AFAIK, there's no way to run an assertion after a suspending function is invoked but before it returns (resumes with a return value). Is this possible?

Currently, mocking suspending functions return immediately when invoked. I would like to control the timing of when they resume with a value. Is this possible? Use case for loading some async data is:

1. suspending function is invoked (without returning yet)
2. assert that loading indicator is shown
3. allow previously invoked suspending function to resume with value
4. assert that loading indicator is no longer shown

Does MockitoK have a way to do this?

Mockito-kotlin does not have a way of handling this, but coroutines-core does I believe (might require a serious refactoring though, depending of how your solution is designed).

You should have a closer look at this - I recommend having a look at the tests in the PR as I find them excellent for learning how to use it.

Btw. I haven't tried it out yet, but theoretically it should be possible.

@ZakTaccardi Did you try the solution @bohsen proposed? Is it sufficient enough?

[ZakTaccardi]

I actually haven't had the time to try it yet. I do plan on giving it a spin and reporting back here

EDIT (Jan 18, 2019 ): I still haven't tried it yet. Note: It would be much nicer to access the Continuation directly via Mockito somehow...
