mock如何为空

I try to run this test:

@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);

...

}

but I get NullPointerException for:

Mockito.when(routingClientMock.

what am i missing?

解决方案

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 {

// ...

}

}
