Como fazer testes de aceitação no Android?

 public class PrimeiraActivity extends Activity {
@Override protected void onCreate(Bundle savedInstance) { super.onCreate(savedInstance); setContentView(R.layout.activity\_primeira); }
@Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu, menu); return super.onCreateOptionsMenu(menu); } } 

 <menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="@+id/menu\_segunda\_activity" android:showAsAction="always" android:title="Segunda Activity"/>
</menu> 

 public class PrimeiraActivity extends Activity {
//código digitado anteriormente...
@Override public boolean onMenuItemSelected(int featureId, MenuItem item) { if(item.getItemId() == R.id.menu\_segunda\_activity) { Intent segunda = new Intent(this, SegundaActivity.class); startActivity(segunda); } return super.onMenuItemSelected(featureId, item); } } 

 public class SegundaActivity extends Activity{
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity\_segunda); } } 

 Ctrl+N -> Android -> Android Test Project 

 public class PrimeiraActivityAcceptanceTest extends ActivityInstrumentationTestCase2<PrimeiraActivity> {
public PrimeiraActivityAcceptanceTest(){ super(PrimeiraActivity.class); } } 

 public class PrimeiraActivityAcceptanceTest extends ActivityInstrumentationTestCase2<PrimeiraActivity> {
private PrimeiraActivity primeiraActivity; private Instrumentation instrumentation;

@Override protected void setUp() throws Exception { super.setUp(); setActivityInitialTouchMode(true); primeiraActivity = getActivity(); instrumentation = getInstrumentation(); } }

@Override protected void setUp() throws Exception { super.setUp(); setActivityInitialTouchMode(true); primeiraActivity = getActivity(); instrumentation = getInstrumentation(); }
public void testAoClicarNoMenuDeveChamarSegundaActivity() throws Exception {
} } 

 public void testAoClicarNoMenuDeveChamarSegundaActivity() throws Exception { sendKeys(KeyEvent.KEYCODE\_MENU); } 

 public void testAoClicarNoMenuDeveChamarSegundaActivity() throws Exception { sendKeys(KeyEvent.KEYCODE\_MENU);
instrumentation.invokeMenuActionSync( primeiraActivity, R.id.menu\_activity\_proxima, 0); }
