我正在使用mockito/powermock版本1.7.0，Spring Boot 2.0.0 M2，Kotlin 1.3.0。Mockito/Powermock與Kotlin無法正常工作
我正在測試Spring @Service類，它注入了一個Repository。 我想在我的測試中嘲笑這個存儲庫，所以我只能測試這個類本身。
我是新來科特林，但我來自爪哇，所以我想這樣做「Java的方式」，但也許我失去了一些東西......
這裏是我的服務接口：
interface MyService {
fun create(myObject: MyObject): MyObject
}
...及其實施：
@Service
class DefaultMyService : MyService {
@Autowired
lateinit var myRepository: MyRepository
override fun create(myObject: MyObject): MyObject = this.myRepository.insert(myObject)
}
這裏是我的倉庫（我使用Spring數據與蒙戈）：
interface MyRepository: MongoRepository<MyObject, String>
這裏是我的測試類：
@RunWith(PowerMockRunner::class)
@PrepareForTest(MyService::class)
class MyServiceTest {
@Mock
lateinit var myRepository: MyRepository
@InjectMocks
lateinit var myService: MyService
@Test
fun shouldDoSomething() {
val myObject = MyObject(name = "Marco")
`when`(myRepository.insert(myObject)).thenReturn(myObject)
assertEquals(myObject.name, this.myService.create(myObject).name)
}
}
當我運行這個測試，發生異常：

我在做什麼錯？我認爲這是一個配置問題，但我無法確切知道錯誤在哪裏。
您正在使用什麼版本PowerMock和的的Mockito？在這個例子中，它也看起來沒有必要使用PowerMock，當你可以使用kotlin-allopen或者http://hadihariri.com/2016/10/04/Mocking-Kotlin-With-Mockito/ –
