用RxJava和Mockito创建android单元测试行不通

Question

class LoginActivityPresenter(private var authUseCase: AuthStructure, private var view: LoginActivityView, private var database: SupervisorDatabaseInterface) {

        fun tryLogin(identifier: String, password: String) {
            val disposable = database.getQrCode() //this retuns Single<QRCode>
                    .doOnSubscribe { view.showProgressDialog() }
                    .doAfterTerminate { view.hideProgressDialog() }
                    .flatMap { it -> authUseCase.authenticate(identifier, password, it.qrcode) }//this retuns Single<UserToken>
                    .subscribe(
                            {
                                database.insertUserToken(it)
                                view.loginSucess()
                            },
                            {
                                when (it) {
                                    is EmptyResultSetException -> {
                                        view.loginErrorNoQrCode()
                                    }
                                    else -> {
                                        view.loginError()
                                        it.printStackTrace()
                                    }
                                }
                            }
                    )
        }
    }

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

    @Mock
    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()
    }
}

MLoginActivityView.LoginError（）；->在id.teste.supervisor.presenters.login.loginActivityPresenter$tryLogin$Disposable$5.accept(loginActivitypresenter.kt:25)

MLoginActivityView.HideProgressDialog（）；->在id.teste.supervisor.presenters.login.loginActivityPresenter$tryLogin$Disposable$2.run(loginActivitypresenter.kt:12)

需要但未调用：MLoginActivityView.LoginSucess（）；->在id.teste.supervisor.presenters.login.loginactivitypresentertest.成功登录时应发生（loginactivitypresentertest.kt:78)

但是，与此模拟的交互正好有3个：mLoginActivityView.ShowProgressDialog（）；->在id.teste.supervisor.presenters.login.loginActivityPresenter$tryLogin$Disposable$1.accept(loginActivitypresenter.kt:11)

MLoginActivityView.LoginError（）；->在id.teste.supervisor.presenters.login.loginActivityPresenter$tryLogin$Disposable$5.accept(loginActivitypresenter.kt:25)

MLoginActivityView.HideProgressDialog（）；->在id.teste.supervisor.presenters.login.loginActivityPresenter$tryLogin$Disposable$2.run(loginActivitypresenter.kt:12)

Answer 1

`when`(mAunthStructure.authenticate(any(), any(), any())).thenReturn(
    Single.just(
        UserToken() 
)
