val condition: suspend () -> AppResult<Playlist>实际上的问题是，由于可暂停的 lambda 作为争论（ ），我无法模拟私有函数
所以，在这方面我需要你的帮助。
要测试的代码，
class UserPlayListManagerImpl(
private val dispatcher: AppCoroutineDispatchers,
private val createPlayListUseCase: CreatePlayListUseCase
) : UserPlayListManager, CoroutineScope {
override lateinit var selectedPlayList: Playlist
init {
createEmptyPlayListForCurrentUser()
setSelectedPlaylist()
}
override fun createEmptyPlayListForCurrentUser() {
evaluateSealedClassWithCondition(condition = {
createPlayListUseCase(selectedUser)
}, success = {
listOfPlayListForCurrentUser.add(it)
})
}
private fun evaluateSealedClassWithCondition(
condition: suspend () -> AppResult<Playlist>,
success: (Playlist) -> Unit, error: (String) -> Unit = {}
) {
launch( handler) {
when (val data = condition()) {
is AppError -> {
withContext(dispatcher.main) {
error(data.message!!)
}
}
is AppSuccess -> {
withContext(dispatcher.main) {
success(data.data)
}
}
}
}
}
override val coroutineContext: CoroutineContext
get() = dispatcher.io + Job()
lateinit var errorMessage: String
private val handler : CoroutineExceptionHandler
get() = CoroutineExceptionHandler { _, exception ->
errorMessage = exception.localizedMessage ?: "An Error occurred"
}
}
测试文件：
@ExtendWith(value = [MockKExtension::class, InstantExecutorExtension::class])
class UserPlayListManagerImplTest {
@JvmField
@RegisterExtension
val coroutinesTestRule = MainCoroutineRule()
@MockK

@MockK

@MockK

fun setUp() {
MockKAnnotations.init(this, relaxed = true)
userPlayListManager = spyk(UserPlayListManagerImpl(
coroutinesTestRule.testDispatcherProvider, createPlayListUseCase,
addTrackUseCase, deleteTrackUseCase), recordPrivateCalls = true)
}
@Test
fun `Create an empty playlist for loggedIn User`() = coroutinesTestRule.runBlockingTest {
val condition: suspend () -> AppResult<Playlist> = {
createPlayListUseCase(getTestNormalUser())
}
val success: (Playlist) -> Unit = mockk(relaxed = true)
val error: (String) -> Unit = mockk(relaxed = true)
coEvery {
createPlayListUseCase(any())
} returns AppSuccess(createEmptyPlayList(getTestNormalUser()))
every {
userPlayListManager invoke "evaluateSealedClassWithCondition" withArguments
listOf(condition, success, error)
} returns Unit
userPlayListManager.createEmptyPlayListForCurrentUser()
verify {
userPlayListManager invoke "evaluateSealedClassWithCondition" withArguments
listOf(condition, success, error)
}
}
}
例外：
can't find function evaluateSealedClassWithCondition(() -> app.template.base.useCases.AppResult<reprator.module.modulea.modals.Playlist>, Function1(#5), Function1(#6)) of class reprator.module.modulea.UserPlayListManagerImpl for dynamic call.
If you were trying to verify a private function, make sure to provide type information to exactly match the functions signature.
