我实际上试图设置一些单元测试与咖啡和经过几个小时的研究，应用程序只做点击，并获得焦点的编辑文本，但之后没有什么

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

我已经删除了所有的动画和SwipeRefreshLayout，因为我看到有一个与swipefresh错误
我实际上使用了一些回调函数来替换Activity中的当前片段
如果有人有一些提示，我在搜索u_u 4小时后就出来了。
Thank you：）
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'

我在defaultConfig中添加了以下内容：

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());
    }
}

我的活动：

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();
    }
}

我的LoginFragment：

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();
        }
    });
}
