Bei der Verwendung von MockK -Coverify wurde die Methode nicht aufgerufen ⇐ Android

[Anonymous]

Der folgende Test fällt aus. Ich habe es manuell getestet und es funktioniert. Aber ich bin mir nicht sicher, warum die Methode nicht aufgerufen wird. Ich nehme an, es hat damit zu tun, dass ich eine Methode in einer Coroutine teste. Ich verwende jedoch einen TestRule , der den Dispatcher auf einen TestDispatcher setzt, der dem Präsentator injiziert wird. Und alle Kommentare zu einem Teil des Codes sind willkommen.
Danke!

Code: Select all

@RunWith(JUnit4::class)
class RegisterPresenterTest {

@get:Rule
var coroutinesTestRule = CoroutineTestRule()

@MockK
lateinit var viewMock: IRegisterView

@MockK
lateinit var service : UserManagementServiceImpl

private lateinit var presenter: RegisterPresenter

@Before
fun setUp() {
MockKAnnotations.init(this)
presenter =
RegisterPresenter(viewMock, coroutinesTestRule.testDispatcherProvider)
}

@Test
fun `shouldCreateNewUser`() = coroutinesTestRule.testDispatcher.runBlockingTest {
// given
val userDetails = UserDetails(
username = "user1", password = "123",
name = "Juan", surname = "Doe", email = "[email protected]"
)
coEvery {
service.verifyUserIsNotInDatabase(userDetails.username, userDetails.email)
} returns UserExistence(usernameInDatabase = false, emailInDatabase = false)

// when
presenter.createNewUser(userDetails)

// then
coVerify(exactly = 1) { service.createNewUser(userDetails) }
}
