Espresso - check which Activity is opened using intent on button press?

Question

Is it possible to trace which Activity is opened after a certain button is pressed?
I have a test in which, when a button is clicked / pressed, it sends a request to the server. Till the time the request is sent, it opens an Activity. To verify the successful execution of the test, I need to check what is the open Activity.

Example of my test:

Check which Intent is opened in Espresso ---

 private void startTest() {
    recreateAuthData(InstrumentationRegistry.getTargetContext(), "d78269d9-9e00-4b8d-9242-815204b0a2f6", "3f32da21-914d-4adc-b6a1-891b842a2972");

    InstrumentationRegistry.getTargetContext().getSharedPreferences(ActivitySplashScreen.class.getSimpleName(),
            Context.MODE_PRIVATE).edit().putInt(ActivitySplashScreen.PROPERTY_APP_VERSION, ActivitySplashScreen.getAppVersion(InstrumentationRegistry.getTargetContext())).commit();
    InstrumentationRegistry.getTargetContext().getSharedPreferences(ActivitySplashScreen.class.getSimpleName(),
            Context.MODE_PRIVATE).edit().putString(ActivitySplashScreen.PROPERTY_REG_ID, "testKey").commit();

    mActivityRule.launchActivity(setIntent());
    // inputPinCode("2794");
}

@Test
public void testIdent() {
    startTest();
    onView(withText("ПРО")).perform(click());
    putDelay(500);
    onView(withId(R.id.get_pro)).perform(click());
    onView(withText("Авторизация по паспортным данным")).perform(click());
    putDelay(500);
    closeSoftKeyboard();
    onView(withId(R.id.btn_goto_passport)).perform(click());
    onView(withHint("Серия и номер паспорта")).perform(replaceText("9894657891"));
    onView(withHint("Дата выдачи паспорта")).perform(replaceText("17032014"));
    onView(withHint("Дата рождения")).perform(replaceText("31091994"));
    onView(withHint("СНИЛС")).perform(replaceText("54665285919"));
    putDelay(500);
    Log.d("TestWidget", hasComponent(hasShortClassName("ActivityMain")).toString());
    onView(withId(R.id.btn_next)).perform(click());
    // some code which check which activity is display now
    putDelay(500);

}

To actually match a started activity with Espresso intents you need to check for the component of the new intent:

intended(hasComponent(NewActivity.class.getName()));

Make sure to call Intents.init() in the setup and Intents.release() in teardown to be able to record intents with Espresso.

This actually checks whether the activity is present in the list of recorded intents. And this would also throw an error if the same activity was opened earlier. So be cautious to use it. – Shivam Pokhriyal Aug 22 '20 at 15:09

Whether it is possible to trace which the Activity opened after pressing the button?

Check espresso-intents library:

Configuration

Add to your app/build.gradle these lines:

androidTestCompile 'com.android.support.test:runner:0.5'
androidTestCompile 'com.android.support.test:rules:0.5'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.2'

NOTICE: espresso-intents won't run without espresso-core, runner or rules libs.

You may also need to change ActivityTestRule<> to IntentsTestRule as it is described here:

IntentsTestRule

Use IntentsTestRule instead of ActivityTestRule when using Espresso-Intents. IntentsTestRule makes it easy to use Espresso-Intents APIs in functional UI tests. This class is an extension of ActivityTestRule, which initializes Espresso-Intents before each test annotated with @Test and releases Espresso-Intents after each test run. The activity will be terminated after each test and this rule can be used in the same way as ActivityTestRule.

From: https://google.github.io/android-testing-support-library/docs/espresso/intents/

Example code (click on button to launch new activity)

Here's a solution using espresso-intents for similar problem:

An example test with intent stubbing:

@Test
 public void testActivityResultIsHandledProperly() {
   // Build a result to return when a particular activity is launched.
   Intent resultData = new Intent();
   String phoneNumber = "123-345-6789";
   resultData.putExtra("phone", phoneNumber);
   ActivityResult result = new ActivityResult(Activity.RESULT_OK, resultData);

   // Set up result stubbing when an intent sent to "contacts" is seen.
   intending(toPackage("com.android.contacts")).respondWith(result));

   // User action that results in "contacts" activity being launched.
   // Launching activity expects phoneNumber to be returned and displays it on the screen.
   user.clickOnView(system.getView(R.id.pickButton));

   // Assert that data we set up above is shown.
   assertTrue(user.waitForText(phoneNumber));
 }
