I send an intent from activity1 to activity2, after clicking on a button. I send extras with this intent.
Using espresso, I need to test whether the activity2 received this intent, sent from activity1.
I have no idea, how to do it. I have not written any code.
Let's say from ActivityA you click a button which starts ActivityB:
Intent intent = new Intent(this, ActivityB.class);
intent.putExtra("MY_EXTRA", "MY EXTRA VALUE");
A test which checks that you're sending the right data to ActivityB would be:
@Rule
public IntentsTestRule<ActivityA> intentsTestRule = new IntentsTestRule<>(ActivityA.class);
@Test
public void testIntents() {
//from ActivityA, click the button which starts the ActivityB
onView(withText("ClickMe")).perform(click());
//validate intent and check its data
intended(allOf(
toPackage("com.your.package.name"),
hasExtra("MY_EXTRA", "MY EXTRA VALUE")
));
}
Check out the examples provided by google: https://github.com/googlesamples/android-testing/tree/master/ui/espresso/IntentsBasicSample
and some documentation here: https://developer.android.com/training/testing/espresso/intents.html .
first use getIntent()
Intent intent = getIntent();
then using intent object to receive data from another activity
String id = intent.getStringExtra("your key");
