Java Android测试-机器人分子+；莫基托+；需要改型但未调用错误

尝试使用Robolectric和Mockito在我的Android应用程序中测试我的改装呼叫，但我遇到以下错误：

需要但未调用：mockApi.register( , ); ->实际上，在ServiceTest.testAPI（ServiceTest.java:58）上，与这个模拟的交互是零

改型API调用在接口中定义如下：

@FormUrlEncoded
@POST("/register")
void register(
        @FieldMap Map<String, String> registrationParams,
        Callback<JsonObject> response) ;

@Config(constants = BuildConfig.class)
@RunWith(TestRunner.class)
public class SharedServiceTest {

private RegistrationActivity activity;
@Mock
private SharedService mockApi;

@Captor
private ArgumentCaptor<Callback<JsonObject>> cb;


@Before
public void setUp() {

    MockitoAnnotations.initMocks(this);
    ActivityController<RegistrationActivity> controller = Robolectric.buildActivity(RegistrationActivity.class);
    activity = controller.get();

    controller.create();
}

@Test
public void testAPI() throws Exception {

    activity.populateFields();
    activity.validateFields();
    activity.register("");

    Mockito.verify(mockApi).register(Mockito.anyMap(), cb.capture());

    JsonObject jsonObject = new JsonObject();
    jsonObject.addProperty("sessionToken", Mockito.anyString());
    jsonObject.addProperty("userId", Mockito.anyString());

    cb.getValue().success(jsonObject, null);

    Assert.assertTrue(ShadowToast.getTextOfLatestToast().contains("Registration completed"));

}

}

public void register(){

       MyApplication.getInstance().getSharedService().register(mRegistrationParams, new Callback<JsonObject>() {
            @Override
            public void success(JsonObject jsonObject, retrofit.client.Response response) {
                Toast.makeText(RegistrationActivity.this, "Registration completed", Toast.LENGTH_LONG).show();
            }

            @Override
            public void failure(RetrofitError error) {
                Toast.makeText(RegistrationActivity.this, RetrofitUtils.getErrorMessage(error), Toast.LENGTH_LONG).show();
            }
        });

    }

我已经搜索了上的其他问题，因此出现了此错误，但没有一个与我在这里尝试做的匹配，也没有为我的问题提供解决方案，所以我只是想知道我做错了什么？

您的

TestMyApplication

中的

共享服务的模拟实例与您声明的测试类不同。
Mockito.verify（mockApi.register）（Mockito.anyMap（），cb.capture（））失败，因为实际上从未调用
mockApi
字段引用的实例。
另一个问题是，
TestMyApplication
中的getter总是为每次调用返回一个新的mock：

    @Override public CPSharedService getCPSharedService() {
        return Mockito.mock(SharedService.class); //this creates a new "mocked" instance 
    }

我对您的场景不是100%清楚，但如果您可以让测试在TestMyApplication实例中设置mockApi字段的实例，则会更好：

public class TestMyApplication extends MyApplication
        implements TestLifecycleApplication {

    private SharedService sharedService;

    @Override
    public void onCreate() {
        super.onCreate();
    }

    @Override public void beforeTest(Method method) {
    }

    @Override public void prepareTest(Object test) {
    }

    @Override public void afterTest(Method method) {
    }

    @Override public CPSharedService getCPSharedService() {
        return this.sharedService;
    }

    public void setCPSharedService(SharedService sharedService) {
        // store your mock
        this.sharedService = sharedService;
    }
}

在你的测试课上：

@Test
public void testAPI() throws Exception  {

    // configure you TestMyApplication
    assertTrue(MyApplication.getInstance() instanceof TestMyApplication);
    TestMyApplication testMyApp = (TestMyApplication) MyApplication.getInstance();
    testMyApp.setCPSharedService(this.mockApi);

    activity.populateFields();
    activity.validateFields();
    activity.register("");

    Mockito.verify(this.mockApi).register(Mockito.anyMap(), cb.capture());

    ...

}

@Test
public void testAPI() throws Exception  {

    // configure you TestMyApplication
    assertTrue(MyApplication.getInstance() instanceof TestMyApplication);
    TestMyApplication testMyApp = (TestMyApplication) MyApplication.getInstance();
    testMyApp.setCPSharedService(this.mockApi);

    activity.populateFields();
    activity.validateFields();
    activity.register("");

    Mockito.verify(this.mockApi).register(Mockito.anyMap(), cb.capture());

    ...

}
