本文介紹了模擬實(shí)例在@Mock 注釋后為空的處理方法，對(duì)大家解決問(wèn)題具有一定的參考價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)吧！
問(wèn)題描述
我嘗試運(yùn)行這個(gè)測(cè)試:
@Mock IRoutingObjHttpClient routingClientMock;
@Mock IRoutingResponseRepository routingResponseRepositoryMock;
@Test
public void testSendRoutingRequest() throws Exception {
CompleteRoutingResponse completeRoutingResponse = new CompleteRoutingResponse();
completeRoutingResponse.regression_latencyMillis = 500L;
Mockito.when(routingClientMock.sendRoutingRequest(any(RoutingRequest.class))).thenReturn(completeRoutingResponse);
RoutingObjHttpClientWithReRun routingObjHttpClientWithReRun = new RoutingObjHttpClientWithReRun
(routingClientMock, routingResponseRepositoryMock);
...
}
但我得到 NullPointerException:
but I get NullPointerException for:
Mockito.when(routingClientMock.
我錯(cuò)過(guò)了什么?
推薦答案
當(dāng)你想使用 @Mock 注解時(shí)你應(yīng)該使用 MockitoJUnitRunner
When you want to use the @Mock annotation you should use the MockitoJUnitRunner
@RunWith(MockitoJUnitRunner.class)
public class MockitoTest {
@Mock
private IRoutingObjHttpClient routingClientMock;
@Test
public void testSendRoutingRequest() throws Exception {
// ...
}
}
