向Mockwebserver发送请求后，测试将挂起。不再进行进一步检查

Question

我正在使用Espresso框架编写UI测试，我需要模拟服务器响应，因此我使用Mockwebserver。 但是执行onView（withId（R.id.fragment_login_btn_enter））。perform（click（））;之后不执行进一步检查（由调试器检查）。尽管Web服务器响应并且应用程序正常运行。有什么问题吗？

这是测试和调度程序的代码：

LoginUINetworkTest.java

@RunWith(AndroidJUnit4.class)
public class LoginUINetworkTest extends ActivityWithMockingNetworkUITest<LoginScreen> {
    @Override
    protected Class<LoginScreen> provideActivityClass() {
        return LoginScreen.class;
    }

    @Override
    protected Dispatcher provideDispatcher(String testName) {
        return new SuccessAuthorizeDispatcher(InstrumentationRegistry.getInstrumentation().getTargetContext());
    }

    @Test
    public void uiNetSuccessLogin() {
        LoginScreen activity = activityRule.getActivity();
        FragmentManager supportFragmentManager = activity.getSupportFragmentManager();

        DialogFragmentIdlingResource dialogFragmentIdlingResource = new DialogFragmentIdlingResource(
                LoginScreen.BOTTOM_LOGIN_TAG,
                supportFragmentManager
        );

        onView(withId(R.id.activity_login_btn_login)).perform(click());

        idlingBlock(dialogFragmentIdlingResource, () -> {
            onView(withId(R.id.fragment_login_et_passphrase))
                    .check(matches(isDisplayed()));

            onView(withId(R.id.fragment_login_et_passphrase))
                    .perform(typeText(InstrumentedTestConstants.PASSPHRASE))
                    .perform(closeSoftKeyboard());

            onView(withId(R.id.fragment_login_btn_enter)).perform(click());
        });

        String mainActivity = MainScreen.class.getName();
        ActivityIdlingResosurce activityIdlingResosurce = new ActivityIdlingResosurce(mainActivity);

        idlingBlock(activityIdlingResosurce, () -> {
            onData(withId(R.id.list_item_wallet_card_tv_balance)).check(matches(withText("0.100")));
        });

    }
}

ActivityWithMockingNetworkUITest.java

public abstract class ActivityWithMockingNetworkUITest<T extends Activity> {
    @Rule
    public final ActivityTestRule<T> activityRule;

    @Rule
    public final TestName testNameRule = new TestName();

    protected MockWebServer mockWebServer = new MockWebServer();

    public ActivityWithMockingNetworkUITest() {
        activityRule = new ActivityTestRule<>(provideActivityClass(), true, false);
    }

    protected abstract Class<T> provideActivityClass();

    protected abstract Dispatcher provideDispatcher(String testName);

    @Before
    public void setup() throws IOException {
        mockWebServer.start(8080);
        mockWebServer.setDispatcher(provideDispatcher(testNameRule.getMethodName()));

        Intents.init();

        activityRule.launchActivity(null);
    }

    @After
    public void teardown() throws IOException {
        Intents.release();
        mockWebServer.shutdown();
    }

    protected void idlingBlock(IdlingResource idlingResource, Runnable runnable) {
        IdlingRegistry.getInstance().register(idlingResource);
        runnable.run();
        IdlingRegistry.getInstance().unregister(idlingResource);
    }
}

SuccessAuthorizeDispatcher.java

public class SuccessAuthorizeDispatcher extends Dispatcher {
    private Context context;
    private Map<String, String> responseFilesByPath = new HashMap<>();

    public SuccessAuthorizeDispatcher(Context context) {
        this.context = context;

        responseFilesByPath.put("/api/accounts", "account/get_0_01_balance_account.json");
    }

    @Override
    public MockResponse dispatch(RecordedRequest request) throws InterruptedException {
        MockResponse errorResponse = new MockResponse().setResponseCode(401);

        Uri parsed = Uri.parse(request.getPath());
        if (parsed == null) { return errorResponse; }
        String pathWithoutQueryParams = parsed.getPath();
        String responseFile = responseFilesByPath.get(pathWithoutQueryParams);

        if (responseFile != null) {
            String responseBody = AssetReaderUtil.asset(context, responseFile);
            return new MockResponse().setResponseCode(200).setBody(responseBody);
        } else {
            return errorResponse;
        }
    }
}
