【问题描述】:
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,它们会随着输出而下降:
org.mockito.exceptions.misusing.InvalidUseOfMatchersException: 参数匹配器的使用无效!预期 0 个匹配器,记录 1 个: -> 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(), "原始字符串");使用匹配器时,所有参数都必须由匹配器提供。例如: //正确的: someMethod(anyObject(), eq("String by matcher"));
如果你在调试模式下运行相同的代码并运行所有行,那么当你调用shared.getToken()时,返回我们指定的值。但是在正常启动的情况下,测试就落在了这条线上。
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?)
}
演讲者:
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!
