Espresso intent test failing

Question

I\'m learning android instrumentation testing with espresso. I have an app which has a drawer menu and there is a menu called About. I was testing click on that menu item and co

Answer 1

I had the same problem, however, switching to IntentsTestRule did not work, too. So I switch back to ActivityTestRule and called Intents.init() before and Intents.release() after the test which sent the Intent.

Answer 2

I had the same problem and solved it by using IntentsTestRule instead of ActivityTestRule. IntentsTestRule is a subclass of ActivityTestRule. Set up your @Rule which creates the activity like so:

@Rule
public IntentsTestRule<MyActivity> mActivity = new IntentsTestRule<MyActivity>(MyActivity.class) {
    @Override
    protected Intent getActivityIntent() {
        ...
    }
};

If you are using a custom ActivityTestRule, you can add the proper Intents.init(), Intents.release() calls:

@Override
protected void afterActivityLaunched() {
    Intents.init();
    super.afterActivityLaunched();
}

@Override
protected void afterActivityFinished() {
    super.afterActivityFinished();
    Intents.release();
}

Instead of using IntentsTestRule which is now @deprecated in java, you should use the recommended activityScenarioRule like so:

@RunWith(AndroidJUnit4::class)
@MediumTest
class YourActivityTest {

    @get:Rule
        val activityScenario = activityScenarioRule<YourActivity>()

    @Before
        fun setUp() {
            launchActivity<YourActivity>()
            Intents.init()
        }
    
        @After
        fun tearDown() {
            Intents.release()
        }

    @Test
        fun should_goBackTo_MainActivity_onBackButton_click() {

            onView(withId(R.id.goBackBtn)).perform(click())
            intended(hasComponent(hasShortClassName(".MainActivity")))
        }
}

Don't forget adding this in your build.gradle file:

android {
defaultConfig {
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
testOptions {
unitTests {
includeAndroidResources = true
}
}
// testing
androidTestImplementation 'androidx.test:core:1.3.1-alpha02'
androidTestImplementation 'androidx.test:core-ktx:'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'   
//for the activityScenarioRule syntax to work in kotlin,
//We add the ktx version of androidx.test.ext:junit
androidTestImplementation 'androidx.test.ext:junit-ktx:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
androidTestImplementation 'androidx.test.espresso:espresso-contrib:3.3.0'
androidTestImplementation 'androidx.test.espresso:espresso-intents:3.3.0'
androidTestImplementation 'androidx.test:runner:1.3.0'
androidTestImplementation 'androidx.test:rules:1.3.0'
}
