Как проверить настройки предпочтений в Robolectri c?

Question

Я хочу проверить изменения электронной почты в моем приложении Android. Я использую Robolectri c 4.3.1.

У меня есть класс, который загружает фрагмент с настройками.

public class ApplicationPreferencesActivity extends AppCompatActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.fragment_container);
        getSupportFragmentManager()
                .beginTransaction()
                .replace(R.id.container, new SettingsFragment())
                .commit();
    }

}

frag_container:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    tools:context=".zeus.ApplicationPreferencesActivity">

    <FrameLayout
        android:id="@+id/container"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
    </FrameLayout>

</LinearLayout>

В SettingsFragment я загружаю EditTextPreference с электронной почтой.

public class SettingsFragment extends PreferenceFragmentCompat {

    private String TAG = "kb_settings";

    private EditTextPreference locationIntervalPreference;
    private EditTextPreference buildingRadiusPreference;

    @Override
    public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
        setPreferencesFromResource(R.xml.prefs, rootKey);

        EditTextPreference emailPreference = findPreference("email");
        // next onClick and onChange listeners
    }
}

prefs:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/preferences_screen">

    <PreferenceCategory
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:summary="@string/preferences_summary"
        android:title="@string/preferences_button"
        android:id="@+id/preferences_category">

        <EditTextPreference
            android:key="email"
            android:summary="@string/preferences_email_summary"
            android:title="@string/preferences_email_title" />

    </PreferenceCategory>

</PreferenceScreen>

Я добавил класс, чтобы проверить, отображается ли предпочтение.

@RunWith(RobolectricTestRunner.class)
public class ChangeEmailTest {

    private Context context;

    @Rule
    public ActivityTestRule<ApplicationPreferencesActivity> settingsRule =
            new ActivityTestRule<>(ApplicationPreferencesActivity.class, true, false);

    @Before
    public void initEnvironment() {
        //...

        settingsRule.launchActivity(new Intent(ApplicationProvider.getApplicationContext(), ApplicationPreferencesActivity.class));
    }

    @Test
    public void testChangeEmail() {
        onData(allOf(
                is(instanceOf(Preference.class)),
                withKey("email"),
                withSummary(R.string.preferences_email_summary),
                withTitle(R.string.preferences_email_title)))
                .check(matches(isCompletelyDisplayed()))
    }

}

Приведенный выше код генерирует ниже исключения.

Я пытался разрешить это исключение с помощью this и this . Я перепробовал все приведенные ниже случаи, и все не удалось.

onData(PreferenceMatchers.withKey(context.getString(R.string.email)))
       .check(matches(isDisplayed()));

onData(allOf(is(instanceOf(Preference.class)), withTitle(R.string.email)))
        .check(matches(isDisplayed()));

onData(anything())
        .inAdapterView(allOf(
                 isDescendantOfA(withId(R.id.container)),
                 withId(R.id.preferences_category)))
        .atPosition(1)
        .check(matches(isDisplayed()));

onData(allOf(is(instanceOf(Preference.class)), withKey("email")))
        .onChildView(withText(R.string.preferences_email_title))
        .check(matches(isDisplayed()));

onData(anything())
        .atPosition(1)
        .onChildView(withText(R.string.preferences_email_title))
        .check(matches(isDisplayed()));

onData(allOf(is(instanceOf(Preference.class)), withTitle(R.string.preferences_email_title)))
        .check(matches(isDisplayed()));

onData(allOf(is(instanceOf(Preference.class)), withKey("email")))
        .check(matches(isDisplayed()));

onData(PreferenceMatchers.withKey("email"))
        .check(matches(isDisplayed()));

Как решить эту проблему?
