Screenshots are useful for • Acceptance testing • Edge case
• Localization • Multiple devices • Regression testing © Edward Dale, 2016 7
Screenshot testing tools • Espresso tests • Dependency injection •
Dependency mocking • Screengrab • Firebase Cloud Test Lab for Android © Edward Dale, 2016 8
Espresso test setup @MediumTest public class BuyCoachScreenGrab { @Inject DummyUserManager

Automated localized screenshots of your Android app on every device
Screengrab ▶ Fastlane ▶ Fabric ▶ Twitter Combination of command-line tool and classes used in tests © Edward Dale, 2016 10
Screengrab test @Test public void testTestimonialMale() { when(mUserManager.getUser().getGender()).thenReturn(Gender.MALE); mActivityRule.launchActivity(new Intent());
onView(withId(R.id.feature_pager_videos)).perform(scrollTo()); Screengrab.screenshot("buy_coach_male_testimonial"); } © Edward Dale, 2016 11

Screengrab vs Firebase Fight! © Edward Dale, 2016 20
Screengrab • ✅ Free • ✅ No waiting for a
free device • ❌ Limited by your devices © Edward Dale, 2016 21
Firebase • ✅ Easy to setup a test matrix •
✅ Fits well with a CI system • ❌ Have to wait your turn • ❌ Costs money • $5/hour for real device • $1/hour for virtual device © Edward Dale, 2016 22
My suggestion Use both © Edward Dale, 2016 23
Cross-platform test @Test public void testTestimonialMale() { when(mUserManager.getUser().getGender()).thenReturn(Gender.MALE); Activity activity
= mActivityRule.launchActivity(new Intent()); onView(withId(R.id.feature_pager_videos)).perform(scrollTo()); ScreenShotter.takeScreenshot("buy_coach_male_testimonial", activity); Screengrab.screenshot("buy_coach_male_testimonial"); } Screengrab for daily development Firebase for CI regression testing © Edward Dale, 2016 24
