Wie klickt man beim Testen mit Android Espresso auf Aktionsleisten?

Question

Ich benutze Android Espresso, um meine Aktivität zu testen. Ich habe mehrere Aktionsleisten, von denen die meisten im Überlauf versteckt sind. Ich versuche, diesen Test zu laufen, aber der Fehler sagt, dass es keine Ansicht in der Hierarchie ist (anders nicht sichtbar):

@MediumTest 
public void testClickInsertItem() { 
    Espresso.onView(ViewMatchers.withId(R.id.action_insert)).perform(ViewActions.click()); 
} 

Und der Fehler:

android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with id: blogr.vpm.fr.blogr:id/action_insert 
If the target view is not part of the view hierarchy, you may need to use Espresso.onData to load it from one of the following AdapterViews:android.widget.ListView{5283cfb0 VFED.VC. ........ 2,2-762,973 #7f07000b app:id/allitems}

Also, wie soll ich Greifen Sie auf die Schaltfläche mit der ID R.id.action_insert zu?

Ich bemerkte die OverflowMenuButton. Ich könnte darauf klicken, aber ich bekomme dann eine andere Ansichtshierarchie, die nicht wie eine Liste von Aktionselementen aussieht. Soll ich in den View-Hierarchien graben, bis ich mein Action Item finde oder gibt es eine bessere, designierte Möglichkeit, auf Action-Items im Overflow zu klicken? Ich konnte in der Android-Dokumentation keine Dokumentation zu Aktionsleisten finden.

Answer 1

Espresso hat openActionBarOverflowOrOptionsMenu(Context context) Methode, um das Menü der Aktionsleiste zu öffnen. Sie müssen es vor Ihrer Testaktion auf die Menüpunkte setzen.

import static android.support.test.espresso.Espresso.openActionBarOverflowOrOptionsMenu; 

@Test 
public void testClickInsertItem() { 
    openActionBarOverflowOrOptionsMenu(InstrumentationRegistry.getTargetContext()); 
    onView(withId(R.id.action_insert)).perform(click()); 
} 

Answer 2

Hoffe, dass es jemand mit collaspingtoolbar

Ich habe folgendes Menü-Layout helfen können.

Nach Espresso-Recorder verwenden, entdeckte ich die Menütaste

habe ich auch ToolBar und CollapsingToolbarLayout im xml mit withContentDescription Funktion ist klicken, was ich tat in der Prüfung ist nur mit der withContentDescription, um das Menü zu öffnen.

menu.xml

<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto"> 
    <item 
    android:id="@+id/action_more" 
    android:icon="@drawable/ic_more_vert_white_24dp" 
    android:title="@string/menu_action_more" 
    app:showAsAction="always"> 
    <menu> 
     <item 
     android:id="@+id/action_login" 
     android:icon="@drawable/ic_account_circle_black_24dp" 
     android:orderInCategory="100" 
     android:title="@string/menu_login" /> 
     <item 
     android:id="@+id/action_settings" 
     android:icon="@drawable/ic_settings_black_24dp" 
     android:orderInCategory="100" 
     android:title="@string/menu_settings" /> 
     <item 
     android:id="@+id/action_about" 
     android:icon="@drawable/ic_info_black_24dp" 
     android:orderInCategory="100" 
     android:title="@string/menu_about" /> 
    </menu> 
    </item> 
</menu> 

MainTest.java

 @Test 
     public void menu_Login() {   
     onView(withContentDescription(R.string.menu_action_more)) 
      .perform(click()); 
     onView(withText("Login")).perform(click()); 
     intended(hasComponent(LoginActivity.class.getName())); 
     }
