👋🏻 Hey guys, question regarding testing the coroutines. Suppose I have a class like this:

class Launcher(dispatcher: CoroutineDispatcher) {
    private val scope = CoroutineScope(SupervisorJob() + dispatcher)
    
    fun launchItem() {
        scope.launch { /* Do my thing here */ }
    }
}

I suppose the correct way to test this is to use

Dispatchers.setMain(myDispatchers)

in the

@Before

function and then use

runBlocking

in my test function, where I call

launcher.launchItem

, right? Or how should I test a method that’s not

suspend

but launches a

coroutine

inside ?

I usually allow to override the whole

coroutineContext

instead of just the dispatcher in this kind of classes. This way you can make the job a child of your test's

coroutineContext

. Otherwise

runBlocking

and the likes will not wait for your coroutine to finish.

The testing framework has been completely reworked in 1.6.0-RC. The explanations on how to proceed are very well detailed in the new README.
