我尝试模拟项目中的一些方法,以便在调用它们时返回某个值。 但是当你运行测试时,它们会随输出而下降:
org.mockito.exceptions.misusing.InvalidUseOfMatchersException: 参数匹配器的使用无效! 0匹配预期,1记录: - >在com.hodzi.stackviewer.questions.detail.QuestionDetailPresenterTest.voteTest(QuestionDetailPresenterTest.kt:69)
如果匹配器与原始值组合,则可能会发生此异常: //不正确: someMethod(anyObject(),“raw String”);使用匹配器时,所有参数都必须由匹配器提供。例如: //正确: someMethod(anyObject(),eq(“by matcher”));
如果在调试模式下运行相同的代码并运行所有行,则在调用shared.getToken()时,将返回我们指定的值。但是在正常启动时,测试就属于这条线。
代码:
import com.hodzi.stackviewer.questions.QuestionsInteractor
import com.hodzi.stackviewer.utils.Shared
import com.hodzi.stackviewer.utils.Vote
import org.junit.BeforeClass
import org.junit.Test
import org.mockito.ArgumentMatchers
import org.mockito.Mockito
internal class QuestionDetailPresenterTest {
companion object {
lateinit var presenter: QuestionDetailPresenter
lateinit var view: QuestionDetailView
@BeforeClass @JvmStatic
fun setUp() {
val questionsInteractor: QuestionsInteractor =
Mockito.mock(QuestionsInteractor::class.java)
val shared: Shared =
Mockito.mock(Shared::class.java)
Mockito.`when`(shared.getToken()).thenReturn("23")
// Mockito.doReturn("23").`when`(shared).getToken()
view = Mockito.mock(QuestionDetailView::class.java)
presenter = QuestionDetailPresenter(questionsInteractor, shared)
}
}
@Test
fun voteTest() {
presenter.vote(ArgumentMatchers.anyInt(), Vote.QUESTION_DOWN)
Mockito.verify(view).goToAuth()
}
}
共享:
interface Shared {
companion object {
const val KEY_TOKEN: String = "keyToken"
}
fun getToken(): String
fun saveToken(token: String?)
}
主讲人:
class QuestionDetailPresenter(val questionsInteractor: QuestionsInteractor, val shared: Shared) :
BasePresenter<QuestionDetailView>() {
lateinit var question: Question
fun vote(id: Int, vote: Vote) {
print(vote)
if (Strings.isEmptyString(shared.getToken())) {
view?.goToAuth()
return
}
val observable: Observable<out Data> = when (vote) {
Vote.ANSWER_UP -> {
questionsInteractor.answerUpVote(id, shared.getToken())
}
Vote.ANSWER_DOWN -> {
questionsInteractor.answerDownVote(id, shared.getToken())
}
Vote.QUESTION_UP -> {
questionsInteractor.questionUpVote(id, shared.getToken())
}
Vote.QUESTION_DOWN -> {
questionsInteractor.questionDownVote(id, shared.getToken())
}
}
baseObservableData(observable,
{ data ->
run {
Log.d(Const.LOG_TAG, "success")
}
},
{ throwable ->
run {
Log.d(Const.LOG_TAG, "error")
}
}
)
}
}
谢谢!
答案 0 :(得分:1)
你嘲笑shared
没有错,我认为问题在于:
presenter.vote(ArgumentMatchers.anyInt(), Vote.QUESTION_DOWN)
只需使用真实的Int
代替ArgumentMatchers.anyInt()
。
喜欢
presenter.vote(0, Vote.QUESTION_DOWN)
匹配模拟对象上的参数时使用匹配器,例如
val calulator = (mock with Mockito)
when(calculator.divideByTwo(anyInt()).thenReturn(1)
使用任何calculator.divideByTwo(int: Int)
调用时,意味着1
会返回Int
。
调用真实对象的方法来测试它们时(就像使用演示者一样),使用真实参数。
