Salut j'ai le code suivant:
@RunWith(Test9Runner.class)
public class MainActivityTest
{
private MainActivity activity;
private Button pressMeButton;
@Before
public void setUp() throws Exception
{
activity = new MainActivity();
activity.onCreate(null);
pressMeButton = (Button) activity.findViewById(R.id.button1);
}
@Test
public void shouldUpdateResultsWhenButtonIsClicked() throws Exception
{
pressMeButton.performClick();
ShadowActivity shadowActivity = shadowOf(activity);
Intent intent = shadowActivity.getResultIntent();
System.out.print(intent.toString());
}
}
Mais je ne sais pas comment tester que presser pressMeButton a lancé une nouvelle activité. En fait, oui, mais comment écrire le bon test unitaire Robolectric pour ce fait?
Utilisez la variable StartedMatcher
de Robolectric
@RunWith(Test9Runner.class)
public class MainActivityTest {
private MainActivity activity;
private Button pressMeButton;
@Before
public void setUp() throws Exception
{
activity = new MainActivity();
activity.onCreate(null);
pressMeButton = (Button) activity.findViewById(R.id.button1);
}
@Test
public void shouldStartNextActivityWhenButtonIsClicked()
{
pressMeButton.performClick();
assertThat(activity, new StartedMatcher(NextActivity.class));
}
}
Dans Robolectric 2.1.1, vous pouvez vérifier si Intent
commençant une nouvelle Activity
a été émis de la manière suivante.
@RunWith(RobolectricTestRunner.class)
public class MyTest {
private ShadowActivity shadowActivity;
private MyActivity activity;
@Before
public void setup() {
activity = new MyActivity();
shadowActivity = Robolectric.shadowOf(activity);
}
@Test
public shouldStartNewActivityWhenSomething() {
//Perform activity startup
//Do some action which starts second activity, for example View::performClick()
//...
//Check Intent
Intent intent = shadowActivity.peekNextStartedActivityForResult().intent;
assertThat(intent.getStringExtra(MySecondActivity.EXTRA_MESSAGE)).isEqualTo("blebleble");
assertThat(intent.getComponent()).isEqualTo(new ComponentName(activity, MySecondActivity.class));
}
}
Ceci est similaire à ce que je fais. Veuillez noter que la création de Activity
en appelant new Activity()
provoquera des avertissements d’impression Robolectric concernant la création d’activités, ceci peut probablement être mieux fait ...
Mettre à jour ceci pour 3.1.2 car les réponses ci-dessus ne fonctionnaient pas pour moi: -
loginButton.callOnClick();
Intent startedIntent = shadowOf(activity).getNextStartedActivity();
ShadowIntent shadowIntent = shadowOf(startedIntent);
assertEquals(NextActivity.class, shadowIntent.getIntentClass());
Inspiré par la réponse de @ MichK, voici un test complet utilisant la chaîne de méthodes buildActivity
de Robolectric 2.2+:
@Test
public void testStartScheduleActivity() {
HomeScreenActivity homeActivity = Robolectric.buildActivity(HomeScreenActivity.class).create().start().visible().get();
ShadowActivity shadowHome = Robolectric.shadowOf(homeActivity);
Button btnLaunchSchedule = (Button) homeActivity.findViewById(R.id.btnLaunchSchedule);
Robolectric.clickOn(btnLaunchSchedule);
assertThat(shadowHome.peekNextStartedActivityForResult().intent.getComponent(), equalTo(new ComponentName(homeActivity, ScheduleActivity.class)));
}
@Before
public void setUp() throws Exception {
mMainActivity = Robolectric.buildActivity(MainActivity.class)
.create().start().visible().get();
shadowActivity =Shadows.shadowOf(mMainActivity);
hourlyButton = (Button) mMainActivity.findViewById(R.id.hourlyButton);
}
@Test
public void hourlyActivityButtonTest() throws Exception {
Thread.sleep(5000);
hourlyButton.performClick();
Intent intent = shadowActivity.peekNextStartedActivityForResult().intent;
assertThat(intent.getComponent()).isEqualTo(new ComponentName(mMainActivity, HourlyForecastActivity.class));
}
Voici à quoi ça ressemble pour le Robolectric 3
// Click on the image view
mShareLocationImageView.performClick();
// Check the startActivityForResult for ShareUserLocationActivity has been triggered
ShadowActivity shadowActivity = Shadows.shadowOf(mChatWindowsActivity);
Intent intent = shadowActivity.peekNextStartedActivityForResult().intent;
assertThat(intent).hasComponent(new ComponentName(mChatWindowsActivity, ShareUserLocationActivity.class));
