我正在尝试在我的 Android Kotlin 项目中使用 Spek 框架和 nhaarman mockito kotlin 创建一个单元测试。问题是当有嵌套的挂起方法时,我不知道如何模拟响应。这就是我正在尝试的方式

我定义:

    val testCoroutineDispatcher = TestCoroutineDispatcher()
    val testCoroutineScope = TestCoroutineScope(testCoroutineDispatcher)

在任何描述之前

    beforeGroup {
        Dispatchers.setMain(testCoroutineDispatcher) //not sure if this is working properly 
    }
    afterGroup {
        Dispatchers.resetMain() // reset main dispatcher to the original Main dispatcher
        testCoroutineScope.cleanupTestCoroutines()
    }

这是我的小组

    describe("Test view model") {
        val contentRepository by memoized(CachingMode.SCOPE) { mock<ContentRepository>() }
        val contentViewModel by memoized(CachingMode.SCOPE) {
            ContentViewModel(contentRepository)
        }
        describe("When something happens") {
            beforeGroup {
                testCoroutineScope.runBlockingTest {
                    whenever(contentRepository.fetchAllContents(0, 10))
                        .thenReturn(Result.success(content))//This is suspend
                    contentViewModel.setContentPage(0)
                }
            }
            it("should fetch all content from repository with page 0") {
                verifyBlocking(contentRepository) {
                    fetchAllClassContents(0, 10)
                }
            }
        }
    }
})

但我收到以下错误

Argument(s) are different! Wanted:
classContentRepository.fetchAllClassContents(
    0,
    10,
    Continuation at viewmodel.ContentViewModelSpek$1$3$1$4$1.invokeSuspend(ContentViewModelSpek.kt:92)
);
-> at repository.ContentRepository.fetchAllClassContents(ContentRepository.kt:23)
Actual invocation has different arguments:
contentRepository.fetchAllContents(
    0,
    10,
    Continuation at viewmodel.ContentViewModel$setContentPage$1.invokeSuspend(ContentViewModel.kt:26)
);

似乎模拟、方法执行和断言在不同的范围内运行

我找不到任何可以帮助我使用协程创建测试的指南 在此先感谢
