The test is about making the assertions that the methods are called when the execution is successful, but an error is occurring that I cannot solve.
My class:
class LoginActivityPresenter(private var authUseCase: AuthStructure, private var view: LoginActivityView, private var database: SupervisorDatabaseInterface) {
fun tryLogin(identifier: String, password: String) {
val disposable = database.getQrCode()
.doOnSubscribe { view.showProgressDialog() }
.doAfterTerminate { view.hideProgressDialog() }
.flatMap { it -> authUseCase.authenticate(identifier, password, it.qrcode) }
.subscribe(
{
database.insertUserToken(it)
view.loginSucess()
},
{
when (it) {
is EmptyResultSetException -> {
view.loginErrorNoQrCode()
}
else -> {
view.loginError()
it.printStackTrace()
}
}
}
)
}
}
Test class:
class LoginActivityPresenterTest {
private val immediateScheduler = object : Scheduler() {
override fun createWorker(): Worker {
return ExecutorScheduler.ExecutorWorker(Executor { it.run() })
}
}
private fun <T> any(): T {
Mockito.any<T>()
return uninitialized()
}
private fun <T> uninitialized(): T = null as T
@Mock
private lateinit var mLoginActivityView: LoginActivityView
@Spy
private lateinit var mAuthStructure: AuthStructure
@Mock
private lateinit var mSupervisorDatabaseInterface: SupervisorDatabaseInterface
@InjectMocks
private lateinit var mLoginActivityPresenter: LoginActivityPresenter
@Before
fun setup() {
MockitoAnnotations.initMocks(this)
RxJavaPlugins.setInitIoSchedulerHandler { immediateScheduler }
RxAndroidPlugins.setInitMainThreadSchedulerHandler { immediateScheduler }
}
@After
fun tearDown() {
RxJavaPlugins.reset()
RxAndroidPlugins.reset()
}
@Test
fun `should happen when you successfully log in`() {
val userToken = UserToken()
val qrCode = QRCode("qr")
val identifier = "test"
val password = "password"
`when`(mSupervisorDatabaseInterface.getQrCode()).thenReturn(Single.just(qrCode))
mLoginActivityPresenter.tryLogin(identifier, password)
verify(mLoginActivityView, times(1)).showProgressDialog()
verify(mLoginActivityView, times(1)).hideProgressDialog()
verify(mLoginActivityView, times(1)).loginSucess()
verify(mLoginActivityView, never()).loginError()
}
}
The result:
java.lang.NullPointerException: The single returned by the mapper is null
