Robolectric InflateException quando si utilizza il layout personalizzato della barra delle azioni

Question

Ho appena impostato il test Robolectric tramite questo setup e mi viene visualizzato un errore durante il test della mia app.

Ho ristretto il problema fino al ProgressSpinner che è nella mia dogana ActionBar layout. Quando disattivo l'ActionBar personalizzato, il test funziona correttamente. Sto usando la normale barra delle azioni, non ActionBarSherlock.

Esiste una soluzione alternativa?

codice di prova

@RunWith(RobolectricTestRunner.class) 
public class MainActivityTest { 

MainActivity activity; 

@Before 
public void setup() 
{ 
    this.activity = Robolectric.buildActivity(MainActivity.class).create().get(); 
} 

@Test 
public void shouldHaveHappySmiles() throws Exception 
{ 
    String hello = this.activity.getString(R.string.app_name); 
    assertThat(hello, equalTo("LFDate")); 
} 

}

Answer 1

Creare o aggiungere un file project.properties alla directory app (non prova directory se ci sono diversi moduli)

Aggiungere queste due righe al file appena creato

android.library.reference.1=../../build/intermediates/exploded-aar/com.android.support/appcompat-v7/21.0.3 
android.library.reference.2=../../build/intermediates/exploded-aar/com.android.support/support-v4/21.0.3 

percorsi devono indicare i file manifesto di questi riferimenti
