Ho due frammenti associati a un'attività.Test dei frammenti con Robolectric 3.0
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LoginFragment loginFragment = new LoginFragment();
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction =
fragmentManager.beginTransaction();
fragmentTransaction.add(android.R.id.content,loginFragment);
fragmentTransaction.commit();
}
public void userReg(View view){
RegisterFragment regFragment = new RegisterFragment();
FragmentManager fragmentManager1 = getSupportFragmentManager();
FragmentTransaction fragmentTransaction1 =
fragmentManager1.beginTransaction();
fragmentTransaction1.addToBackStack("added");
fragmentTransaction1.replace(android.R.id.content,regFragment);
fragmentTransaction1.commit();
}
}
Il frammento di registrazione collegato tramite un pulsante. Ora voglio testarli entrambi in robolectric 3.0.
@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class,sdk = 21)
public class MainActivityTest {
MainActivity activity;
@Before
public void setUp(){
activity= Robolectric.setupActivity(MainActivity.class);
}
@Test
public void shouldNotBeNull(){
assertNotNull(activity);
LoginFragment loginFragment = new LoginFragment();
startFragment(loginFragment);
assertNotNull(loginFragment);
}
@Test
public void loginFragmentShouldNotBeNull(){
RegisterFragment registerFragment = new RegisterFragment();
startFragment(registerFragment);
assertNotNull(registerFragment);
}
@Test
public void registerFragmentShouldNotBeNull(){
RegisterFragment registerFragment = new RegisterFragment();
startFragment(registerFragment);
assertNotNull(registerFragment);
}
}
Questi linea lamentano
startFragment(loginFragment);
startFragment(registerFragment);
dicendo che StartFragment (android.app.Fragment) non può essere applicato in LoginFragment e registrare frammento rispettivamente.
Per entrambi i frammenti importare
import android.support.v4.app.Fragment;
quindi questa è la causa del problema. Potrei risolvere questo problema, usando i frammenti fissi, ma come usare quelli dinamici?
Qualche idea?
Grazie.
EDIT
è fissato l'errore sopra descritto. Ho appena aggiunto
import static org.robolectric.shadows.support.v4.SupportFragmentTestUtil.startFragment;
Tuttavia, quando eseguo il test ottengo un'altra eccezione.

Ma ora ho un'altra eccezione. – Theo
java.lang.ClassCastException: org.robolectric.shadows.support.v4.SupportFragmentTestUtil $ FragmentUtilActivity non può essere lanciato su android.support.v7.app.AppCompatActivity – Theo
È necessario visualizzare la traccia stack –
