Question

我有关于使用Mockito和Koin依赖注入的单元测试的问题，我想测试ViewModel，我已经注入并模拟了类服务和存储库，但是在运行测试错误there were zero interaction...时，该代码如下：

class HomeViewModelTest: KoinTest {

    val scope = CoroutineScope(Dispatchers.Unconfined)

    val repository: NewsRepository by inject { parametersOf(scope) }

    val service by inject<Service>()

    @Mock
    lateinit var showLoading: Observer<Boolean>

    @Mock
    lateinit var newsList: Observer<List<Article>>

    @Mock
    lateinit var showError: Observer<String>

    @get:Rule
    val rule = InstantTaskExecutorRule()

    lateinit var server: MockWebServer


    @Before
    fun setUp() {
        server = MockWebServer()
        server.start()
        BASE_TEST_URL = server.url("/").toString()

        MockitoAnnotations.initMocks(this)
        startKoin { modules(listOf(appTestModule)) }
        declareMock<NewsRepository>()
        declareMock<Service>()
    }

    @Test
    fun getNewsTest() = runBlocking {
        verify(service, times(1)).getSources(apiKey = API_KEY)
        val sources = arrayListOf<Source>()
        val dataResponse = SourceResponse(sources, "200")
        val response = Response.success(dataResponse)
        `when`(service.getSources()).thenReturn(response)

        val resultCallback = argumentCaptor<(List<Article>?, String?) -> Unit>()
        Mockito.verify(repository).getNewsList(id = eq("us"), response = resultCallback.capture())
    }

    @After
    fun tearDown() {
        stopKoin()
    }
}

和这样的类存储库：

class NewsRepository(private val scope: CoroutineScope) : KoinComponent {
    private val service by inject<Service>()

    fun getSource(response: (List<Source>?, String?) -> Unit) {
        request(
            scope,
            {service.getSources()}, { res ->
            when(res) {
                is Result.Success -> response(res.data.sources, null)
                is Result.Failure -> response(null, res.error)
            }
        })
    }
}

但是此错误显示在验证类HomeViewModelTest中，我试图禁用verify(service)行中的verify(repository)显示错误，并引用了方法request中的行getSource在NewsRepository上，有人可以解决我的问题，我是有关单元测试的初学者

实际上，该模拟游戏的互动为零
