Hi everyone,

This goes back to my earlier post about being able to quickly unit-test functions that execute coroutines.

Especially if these functions have timeouts or delays and you’d like to run each of your tests in milliseconds and not seconds, I wrote a CoroutineContext that allows you to do so.

It is very much like the RxJava’s TestScheduler and its methods triggerActions, advanceTimeBy, etc.
It does so by implementing a Coroutine Dispatcher (for speeding up (virtual) time) and a Coroutine Exception Handler (for testing thrown exceptions).

The main TestCoroutineContext class and some unit-tests can be found here:

Note that there may be some issues with this implementation. This gist is an initial draft.

The attache Unit-tests all run successfully, but I may have missed something.

If you find an issue with the TestCoroutineContext, please let me know. Thank you!
