我已经开始使用UI测试Espresso。我准备自定义MockTestRunner,MockApplication初始化Dagger组件，我也定义了模拟模块。它看起来像：测试运行失败：由于'android.os.NetworkOnMainThreadException'导致测试运行失败
public class MockTestRunner extends AndroidJUnitRunner {
public Application newApplication(ClassLoader cl, String className, Context context)
throws InstantiationException, IllegalAccessException, ClassNotFoundException {
return super.newApplication(cl, MockMyApplication.class.getName(), context);
} }
MyApp由
public class MockQrApplication extends MyApp {
private MockWebServer mockWebServer;
protected void initComponent() {
mockWebServer = new MockWebServer();
component = DaggerMyAppComponent
.builder()
.myAppModule(new MyAppModule(this))
.busModule(new BusModule())
.apiModule(new MockApiModule(mockWebServer))
.facebookModule(new FacebookModule())
.dataManagerModule(new DataManagerModule())
.greenDaoModule(new GreenDaoModule())
.trackModule(new TrackModule(this))
.build();
component.inject(this);
}
}
我加testInstrumentationRunner扩展到gradle
defaultConfig {
....
multiDexEnabled true
testInstrumentationRunner "a.b.c.MockTestRunner"
}
我想运行测试登录我LoginActivity
@RunWith(AndroidJUnit4.class)
@LargeTest
public class LoginActivityTest {
protected Solo solo;
@Rule
public ActivityTestRule<LoginActivity> activityTestRule = new ActivityTestRule(LoginActivity.class);
@Before
public void setUp() throws Exception {
initVariables();
}
protected void initVariables() {
solo = new Solo(InstrumentationRegistry.getInstrumentation(), activityTestRule.getActivity());
}
@Test
public void testLayout() {
solo.waitForFragmentByTag(LoginFragment.TAG, 1000);
onView(withId(R.id.email_input)).perform(clearText(), typeText("[email protected]"));
onView(withId(R.id.pass_input)).perform(clearText(), typeText("qqqqqqqq"));
onView(withId(R.id.login_button)).perform(click());
solo.waitForDialogToOpen();
}
}
当我想运行我的测试中，我得到了：
Client not ready yet..
Started running tests
Test running failed: Instrumentation run failed due to 'android.os.NetworkOnMainThreadException'
Empty test suite.

这是MockApiModule延伸ApiModule类
public class MockApiModule extends ApiModule {
private MockWebServer mockWebServer;
public MockApiModule(MockWebServer mockWebServer) {
this.mockWebServer = mockWebServer;
}
@Override
public OkHttpClient provideOkHttpClient(DataManager dataManager) {
return new OkHttpClient.Builder()
.build();
}
@Override
public Retrofit provideRetrofit(OkHttpClient okHttpClient) {
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(mockWebServer.url("/")) // throw NetworkOnMainThreadException
.addConverterFactory(NullOnEmptyConverterFactory.create())
.addConverterFactory(GsonConverterFactory.create(new Gson()))
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.client(okHttpClient)
.build();
return retrofit;
}
@Override
public ApiService provideApiService(Retrofit retrofit) {
return retrofit.create(ApiService.class);
}
@Override
public ApiClient provideApiManager(Application application, ApiService apiService, DataManager dataManager) {
return new MockApiClient(application, apiService, dataManager, mockWebServer);
}
}
API登录请求看起来像这样：
apiService.postLoginUser(userLoginModel).enqueue(new Callback<JsonObject>() {
@Override
public void onResponse(Call<JsonObject> call, Response<JsonObject> response) {
if (response.isSuccess()) {
LoginResponse loginResponse = null;
try {
loginResponse = gson.fromJson(MockResponse.getResourceAsString(this, "login.json"), LoginResponse.class);
} catch (IOException e) {
e.printStackTrace();
}
callback.onLoginSuccess(loginResponse);
} else {
callback.onLoginFail(response.errorBody().toString());
}
}
@Override
public void onFailure(Call<JsonObject> call, Throwable t) {
callback.onLoginFail(t.getMessage());
}
});
它工作，如果我改变MockMyApplication到MyApp级应用的MockTestRunner
我得到stracktrace

错误消息非常明确，您正在UI线程内进行网络调用。当你在仪表测试中，有一个UI（主）线程，他的行为与在真实设备上启动应用程序时的行为相同。显示可能包含网络调用的代码 –
嘿，Thx为您的答案，我添加了'MockApiModule'和登录请求。我了解错误消息，但我不知道原因。由于Test无法启动，我收到 – Michael
的消息，因此无法在测试线程中使用您的API登录方法。在setUp（）方法中调用某个函数吗？ –
