CoroutineTest
open class CoroutineTest(context: CoroutineContext = EmptyCoroutineContext, testDispatcherBuilder: (TestCoroutineScheduler) -> TestDispatcher = { StandardTestDispatcher(it) }) : CoroutineTestRule, AttachedDisposables
Base class for unit testing coroutine based code.
On every test run this class automatically sets MainScope and dispatchers to use a TestCoroutineDispatcher.
Internally, this uses a CoroutineTestRule which does the actual dispatchers and Dispatchers.setMain() setup. This allows accessing e.g. the testScope in your @Before setup method.
Moreover, this provides an attachedDisposables attribute and a collectFlow helper, so you can activate SharingStarted.WhileSubscribed based flows created with derived, for example.

In addition to running the test this also disposes the attachedDisposables (useful with collectFlow).
