android - 简单 Espresso 测试 "Looped for x iterations over 60sec"错误

Question

我实际上尝试用 Espresso 设置一些单元测试，经过几个小时的研究，该应用程序只执行单击并通过 EditText 获得焦点，但之后什么都没有

Caused by: android.support.test.espresso.AppNotIdleException: Looped for 1996 iterations over 60 SECONDS. The following Idle Conditions failed .

我删除了所有动画和 SwipeRefreshLayout，因为我看到 swiperefresh 有一个错误

我实际上使用了一些回调来替换 Activity 中的当前 fragment

如果有人有一些提示，我会在搜索 u_u 4 小时后离开

谢谢你:)

我的 Gradle 依赖项:

// App dependencies
compile 'com.android.support:support-annotations:23.3.0'
compile 'com.google.guava:guava:18.0'
// Testing-only dependencies
// Force usage of support annotations in the test app, since it is internally used by the runner module.
androidTestCompile 'com.android.support:support-annotations:23.3.0'
androidTestCompile 'com.android.support.test:runner:0.4.1'
androidTestCompile 'com.android.support.test:rules:0.4.1'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.2'

我已经在 defaultConfig 中添加了这个:

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

这是我的测试:

@RunWith(AndroidJUnit4.class)
@LargeTest
public class HelloWorldEspressoTest {

    public static final String USERNAME = "do_f";

    @Rule
    public ActivityTestRule<LoginActivity> mActivityRule = new ActivityTestRule(LoginActivity.class);

    private LoginActivity mActivity = null;

    @Before
    public void setActivity() {
        mActivity = mActivityRule.getActivity();
    }

    @Test
    public void login_LoginActivity() {

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

        onView(withId(R.id.login_username))
                .perform(typeText(USERNAME), closeSoftKeyboard());
    }
}

这是我的 Activity :

public class LoginActivity extends AppCompatActivity
        implements MenuFragment.OnFragmentInteractionListener {

    private FragmentManager fm;

    public static void newActivity(Activity activity)
    {
        Intent i = new Intent(activity, LoginActivity.class);
        activity.startActivity(i);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
        SharedPreferences sp = getSharedPreferences(Utils.SP, Context.MODE_PRIVATE);

        if (!sp.getString(Utils.TOKEN, "null").equals("null"))
        {
            MainActivity.newActivity(this);
            finish();
        }

        fm = getFragmentManager();
        fm.beginTransaction()
                .replace(R.id.container, MenuFragment.newInstance())
                .addToBackStack(null)
                .commit();
    }

    @Override
    public void onBackPressed()
    {
        if (getFragmentManager().getBackStackEntryCount() > 1)
            getFragmentManager().popBackStack();
        else
            super.onBackPressed();
    }

    @Override
    public void showLogin() {
        fm.beginTransaction()
                .replace(R.id.container, LoginFragment.newInstance())
                .addToBackStack(null)
                .commit();
    }

    @Override
    public void showRegister() {
        fm.beginTransaction()
                .replace(R.id.container, RegisterFragment.newInstance())
                .addToBackStack(null)
                .commit();
    }
}

还有我的登录 fragment :

    private static final String        TAG = "LoginFragment";

@Bind(R.id.loading_spinner)
ProgressBar loading;

@Bind(R.id.content)
LinearLayout content;

@Bind(R.id.login_username)
EditText        username;

@Bind(R.id.login_password)
EditText        password;

public LoginFragment() {

}

public static LoginFragment newInstance() {
    return new LoginFragment();
}

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

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.login_fragment_login, container, false);
    ButterKnife.bind(this, v);
    return v;
}

@Override
public void onActivityCreated(Bundle saveInstanceState) {
    super.onActivityCreated(saveInstanceState);
}

@OnClick(R.id.login_submit)
public void onSubmit(View v)
{
    if (username.getText().length() == 0
            || password.getText().length() == 0)
    {
        Snackbar.make(getView(), "blabla", Snackbar.LENGTH_SHORT).show();
        return ;
    }
    //hideContent();
    LoginPost p = new LoginPost(username.getText().toString(), password.getText().toString());
    Call<LoginResponse> call = RestClient.get().login(p);
    call.enqueue(new Callback<LoginResponse>() {
        @Override
        public void onResponse(Call<LoginResponse> call, Response<LoginResponse> response) {
            if (response.body() == null) {
                String msg = getResources().getString(R.string.login_error_bad_credentials);
                Snackbar.make(getView(), msg, Snackbar.LENGTH_SHORT).show();
                //showContent();
            } else {
                SharedPreferences sp = getActivity().getSharedPreferences(Utils.SP, Context.MODE_PRIVATE);
                sp.edit().putString(Utils.TOKEN, response.body().getToken()).apply();
                sp.edit().putString(Utils.USERNAME, username.getText().toString()).apply();
                MainActivity.newActivity(getActivity());
                getActivity().finish();
            }
        }

        @Override
        public void onFailure(Call<LoginResponse> call, Throwable t) {
            Snackbar.make(getView(), "onFailure", Snackbar.LENGTH_SHORT).show();
            //showContent();
        }
    });
}

Answer 1

我找到了解决方案，循环迭代就是由此造成的

<ProgressBar
    android:id="@+id/loading_spinner"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    android:indeterminateTintMode="src_atop"
    android:indeterminateTint="@color/ganjify"
    android:alpha="0"
    android:layout_gravity="center" />

因为我没有在不使用它时将可见性设置为 GONE!

loading.setVisibility(View.GONE);
