MainTestDispatcherExtension

Installs Dispatchers.Main with a TestDispatcher for each test method.

Use with @ExtendWith(MainTestDispatcherExtension::class) or @MainTestDispatcher. Access the active dispatcher via dispatcher when the extension is registered as a field:

@ExtendWith(MainTestDispatcherExtension::class)
class MyViewModelTest {
    @RegisterExtension
    @JvmField
    val main = MainTestDispatcherExtension()

    @Test
    fun loads() = runTest(main.dispatcher) { … }
}
