I have an espresso test which fails because at the start of my fragment, I call launch(Dispatchers.Main) { ... withTimeoutOrNull(1000) }
When I set that timeout to 0, the tests passes because the views are ready.
Now I thought, that in my tests I can set the main dispatcher for advancing the time automatically (so that the timout is thrown immediately and don't need to adjust the production code for my tests):
Dispatchers.setMain(TestCoroutineDispatcher()).
However that doesn't work.
Has someone and idea why and how I can fix it?

are you actually advancing the time in your TestCoroutineDispatcher using advanceTimeBy?
