类Result< out T>期望的一种类型实参. [英] One type argument expected for class Result<out T>

问题描述

我是Kotlin的新手，在某些情况下我不太了解该怎么做.在这里，我需要插入自己的类"Result"，但是我不知道该怎么做.

I'm new to Kotlin and I do not quite understand what to do in some cases. Here I need to plug my own class "Result", but I do not know how to do that.

    @get:Rule
    val taskExecutorRule = InstantTaskExecutorRule()

    private val mockRepository: Repository = mockk()
    private val notesLiveData = MutableLiveData<Result>() //Here it is
    private lateinit var viewModel: MainViewModel

    @Before
    fun setUp() {
        every { mockRepository.getNotes() } returns notesLiveData
        viewModel = MainViewModel(mockRepository)
    }

    @Test
    fun `should call getNotes once`() {
        verify(exactly = 1) { mockRepository.getNotes() }
    }

    @Test
    fun `should return error`() {
        var result: Throwable? = null
        val testData = Throwable("error")
        viewModel.getViewState().observeForever { result = it?.error }
        notesLiveData.value = Result.Error(testData)
        assertEquals(result, testData)
    }
}

推荐答案

我只需要自己通过导入指定该文件的路径

I just needed to specify the path to this file myself through import
