试图使用robolectric和overito在我的android应用中测试我的改造呼叫,但我会收到以下错误:
想要但不调用:mockapi.register( ,,,, ); ->在servicetest.testapi(servicetest.java:58)实际上,与此模拟的相互作用为零。
改装API调用在接口中定义如下:
@FormUrlEncoded
@POST("/register")
void register(
@FieldMap Map<String, String> registrationParams,
Callback<JsonObject> response) ;
我的测试类如下:
@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"));
}
}
使用API的我的注册行为中的方法如下:
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();
}
});
}
真正的改造服务来自我自己的应用程序类
public class TestMyApplication extends MyApplication
implements TestLifecycleApplication {
@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 Mockito.mock(SharedService.class);
}
}
我已经搜索了其他问题,以便有此错误,但它们都不匹配我在这里要做的事情或为问题提供解决方案,所以我只是想知道我在做错了什么?
TestMyApplication
中SharedService
的模拟实例与您声明的测试类别不同。Mockito.verify(mockApi).register(Mockito.anyMap(), cb.capture());
失败了,因为实际上从未调用过mockApi
字段引用的实例。另一个问题是TestMyApplication
中的GETTER总是为每个援引返回一个新的模拟:
@Override public CPSharedService getCPSharedService() {
return Mockito.mock(SharedService.class); //this creates a new "mocked" instance
}
您的场景对我而言并不清楚,但是如果您可以让测试设置testmyapplication实例中的Mockapi字段的实例,那就更好了:
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;
}
}
在您的测试课中:
@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());
...
}
