如何使用干净的架构用例为MVP Presenter编写junit测试用例？

Question

我正在尝试编写遵循干净架构方法的kotlin测试用例。我的主持人课看起来像这样：

    class WeatherDetailsPresenter @Inject constructor(var getCurrentWeatherWithForecastUsecase: GetCurrentWithForcastedWeatherUsecase) : BaseMvpPresenter<WeatherDetailsView>() {

    fun presentCurrentAndForcastedWeather(country: String?) {
        with{getCurrentWeatherWithForecastUsecase) {
            this.countyName = country
            execute(object : DefaultSubscriber<Pair<CurrentWeatherModel, ForecastedWeatherModel>>() {
                override fun onSubscribe(d: Disposable) {
                    super.onSubscribe(d)
                    showLoading(true)
                }

                override fun onNext(t: Pair<CurrentWeatherModel, ForecastedWeatherModel>) {
                    super.onNext(t)
                    view?.showCurrentWeather(t.first)
                }

                override fun onComplete() {
                    super.onComplete()
                    showLoading(false)
                }
            })
        } 
    }
}

我想测试显示的当前天气。到目前为止，这是我为演讲者类进行的junit测试编写的内容：

    @RunWith(MockitoJUnitRunner::class)
class WeatherDetailsPresenterTest {

    lateinit var usecase: GetCurrentWithForcastedWeatherUsecase

    @Mock
    lateinit var repo: WeatherDataRepository

    @Mock
    lateinit var view: WeatherDetailsView

    lateinit var presenter: WeatherDetailsPresenter

    @Before
    fun setUp() {
        usecase = GetCurrentWithForcastedWeatherUsecase(repo)
        presenter = WeatherDetailsPresenter(usecase)

    }

    //https://stackoverflow.com/questions/47083504/what-and-how-to-test-in-a-presenter-with-a-rxandroid-use-case
    @Test
    fun testCurrentWeatherScreenAppears() {
        //arrange
    //given has replaced "when" cmd, and will has replaced "then"
        BDDMockito.given(usecase.execute((ArgumentMatchers.any()))).will { invocation ->
            val observer = invocation.arguments[0] as DefaultSubscriber<Pair<CurrentWeatherModel, ForecastedWeatherModel>>
            observer.onComplete() //i want to test that after this line is called, currentWeather is showing
        }
        //act
        presenter.presentCurrentAndForcastedWeather("indonesia")

        //assert
        BDDMockito.then(view).should().showCurrentWeather(ArgumentMatchers.any())
    }
}

当我处理这样的用例时，有没有更简单的方法来测试是否调用了视图代码？这是进行测试的正确方法吗？
