这似乎是使用Mockito和Retrofit最受欢迎的博客.

不幸的是,它使用了早期版本的Retrofit,并且依赖于Callbacks和RetrofitError,它们已从2.0中断.

你如何使用Retrofit 2.0做到这一点？

P.S.：我正在使用RxJava和改造,所以适用于RxJava的东西会很棒.谢谢！

解决方法 在Retrofit的官方存储库中有一个有用的例子：

Unit Tests

During develop of app,you can send requests the server all time(or
most of time) so it is possible to live without mocked server,it
sucks but is possible. Unfortunately you are not able to write good
tests without the mock. Below there are two unit tests. Actually they
do not test anything but in simple way shows how to mock Retrofit
service using Mockito and Dagger.

@RunWith(RobolectricTestRunner.class)public class EchoServiceTest {    @Inject    protected EchoService loginService;    @Inject    protected ClIEnt clIEnt;    @Before    public voID setUp() throws Exception {        Injector.add(new AndroIDModule(),new RestServicesModule(),new RestServicesMockModule(),new TestModule());        Injector.inject(this);    }    @Test    public voID shouldReturnOfferInAsyncMode() throws IOException {        //given        int expectedQuantity = 765;        String responseContent = "{" +                "   \"message\": \"mock message\"," +                "   \"quantity\": \"" + expectedQuantity + "\"" +                "}";        mockResponseWithCodeAndContent(200,responseContent);        //when        EchoResponse echoResponse = loginService.getMessageAndQuantity("test","test");        //then        assertthat(echoResponse.getQuantity()).isEqualTo(expectedQuantity);    }    @Test    public voID shouldReturnOfferInAsyncModea() throws IOException {        //given        int expectedQuantity = 2;        String responseContent = "{" +                "   \"message\": \"mock message\","test");        //then        assertthat(echoResponse.getQuantity()).isEqualTo(expectedQuantity);    }    protected voID mockResponseWithCodeAndContent(int httpCode,String content) throws IOException {        Response response = createResponseWithCodeAndJson(httpCode,content);        when(clIEnt.execute(Matchers.anyObject())).thenReturn(response);    }    private Response createResponseWithCodeAndJson(int responseCode,String Json) {        return new Response(responseCode,"nothing",Collections.EMPTY_List,new TypedByteArray("application/Json",Json.getBytes()));    }
