12. Espresso Example @Test public void testLogin() { onView(withText("LOGIN")).check(matches(not(isEnabled()))); onView(withId(R.id.username)).perform(typeText("sam")); onView(withText("LOGIN")).perform(click()); }
13. Espresso Example @Test public void testLogin() { onView(withText("LOGIN")).check(matches(not(isEnabled()))); onView(withId(R.id.username)).perform(typeText("sam")); onView(withText("LOGIN")).perform(click()); }
14. Espresso Example @Test public void testLogin() { onView(withText("LOGIN")).check(matches(not(isEnabled()))); onView(withId(R.id.username)).perform(typeText("sam")); onView(withText("LOGIN")).perform(click()); }
15. Target Audience for Espresso “Espresso is targeted at developers, who believe that automated testing is an integral part of the development lifecycle. While it can be used for black-box testing, Espresso’s full power is unlocked by those who are familiar with the codebase under test.”

30. 1. See What is Being Tested 2. Diagnose Failures 3. Share Your Tests
31. NO ONE Sees The Value of Your Tests… YET • Your Boss • Product Owners • Designers • Manual Testers
32. That’s because they can’t tell what your tests are doing and don’t find any use for them. To them it’s just console output.
33. Let EVERYONE see what’s being tested.
34. User Interfaces are VISUAL • A User Interface is something very hard to represent in a non-visual way. • Exercise: ◦ Imagine you need to tell someone who is blind what the Mona Lisa painting looks like. What would you say? https://en.wikipedia.org/wiki/Mona_Lisa
35. Same Test, But Looks Different on Different Devices
36. Android Embraces Differences
37. LANGUAGE DEVICE TYPE DEVICE SIZE ANDROID OS VERSION Fragmentation and Permutations
38. Spoon - http://square.github.io/spoon/
39. Spoon Test Runner java -jar spoon-runner-1.7.0-jar-with-dependencies.jar \ --apk example-app.apk \ --test-apk example-tests.apk • Run instrumentation tests in parallel • Shard tests across multiple devices • Beautiful HTML reports
40. Spoon HTML Reports
41. Visualize What Your Tests are Doing
44. GIFs • Generated by default • Processing overhead ◦ 11 Seconds for 21 Screenshots -> • Disable using “--no-animations”
45. Screenshots - HOW?
46. Screenshot Libraries - Dialog Comparison UiAutomator Falcon Spoon
47. Screenshot Libraries - Overflow Menus Comparison UiAutomator Falcon Spoon
48. Spoon Spoon.screenshot(activity, tag); Spoon.screenshot(activity, tag, testClassName, testMethodName); https://github.com/square/spoon https://github.com/square/spoon/issues/4

52. Get Currently RESUMED Activity private static Activity getCurrentActivityInstance() { final Activity[] activity = new Activity[1]; getInstrumentation().runOnMainSync(new Runnable() { public void run() { Collection resumedActivities = ActivityLifecycleMonitorRegistry.getInstance() .getActivitiesInStage(RESUMED); if (resumedActivities.iterator().hasNext()) { Activity currentActivity = (Activity) resumedActivities.iterator().next(); activity[0] = currentActivity; logger.trace("Activity obtained of type: " + currentActivity.getClass().getName()); } } }); return activity[0]; }
53. Get Test Method & Class from Current Stack Trace public static StackTraceElement getTestMethodStackTraceElement() { StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace(); for (int i = 4; i < stackTrace.length; i++) { StackTraceElement stackTraceElement = stackTrace[i]; try { Method method = Class.forName(stackTraceElement.getClassName()).getMethod( stackTraceElement.getMethodName()); Annotation annotation = method.getAnnotation(Test.class); if (annotation != null) { return stackTraceElement; } } catch (Exception e) { // That's fine, will look at the next stack trace element } } return stackTrace[4]; }
54. Get Test Method & Class from Current Stack Trace public static StackTraceElement getTestMethodStackTraceElement() { StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace(); for (int i = 4; i < stackTrace.length; i++) { StackTraceElement stackTraceElement = stackTrace[i]; try { Method method = Class.forName(stackTraceElement.getClassName()).getMethod( stackTraceElement.getMethodName()); Annotation annotation = method.getAnnotation(Test.class); if (annotation != null) { return stackTraceElement; } } catch (Exception e) { // That's fine, will look at the next stack trace element } } return stackTrace[4]; }
55. Resulting Screenshot Code screenshot(activity, “username_entered”, testClass, testMethod); takeScreenshot(“username_entered”);
56. Screenshots - WHEN?
57. Well… It Depends • ALWAYS on FAILURE • To generate reports for product and design teams • On small/low-res emulators during test development/debugging
58. Screenshots - The Cost?

85. Tips and Tricks
86. NEVER Thread.sleep() • AsyncTask Threadpool ◦ Leverage for Networking and RxJava • Idling Resources - Use CountingIdlingResource ◦ increment(); and decrement(); https://developer.android.com/reference/android/support/test/espresso/contrib/CountingIdlingResource.html
87. Define Your “LOW BAR” Device • Android Emulator Virtual Device • 384x640 • mdpi - 160 dots per inch • Able to run in continuous integration
88. Android Studio - Layout Inspector
89. Android Studio - Layout Inspector
90. Android SDK Hierarchy Viewer
91. Leverage Continuous Integration • Jenkins • Circle CI • BuddyBuild • etc
92. Create a Custom Test Runner • Control test runner behavior without recompiling • Turn on/off all screenshots with a command-line parameter ◦ --e screenshots=true ◦ --e screenshots=false
93. Create a Custom Test Runner public class MyAndroidJUnitRunner extends AndroidJUnitRunner { @Override public void onCreate(Bundle arguments) { // process you parameters here. super.onCreate(arguments); } } defaultConfig { testInstrumentationRunner "com.handstandsam.MyAndroidJUnitRunner" }
94. Create a Custom Test Runner public class MyAndroidJUnitRunner extends AndroidJUnitRunner { @Override public void onCreate(Bundle arguments) { // process you parameters here. super.onCreate(arguments); } } defaultConfig { testInstrumentationRunner "com.handstandsam.MyAndroidJUnitRunner" }
95. Disable Animations
96. Test Butler by LinkedIn “Reliable Android testing, at your service.” • Stabilizes the Android emulator ◦ Disables animations ◦ Disables crash & ANR dialogs ◦ Locks the keyguard, WiFi radio, and CPU to ensure they don't go to sleep unexpectedly while tests are running. • Handles changing global emulator settings and holds relevant permissions so your app doesn't have to. ◦ Enable/disable WiFi ◦ Change device orientation ◦ Set location services mode ◦ Set application locale https://github.com/linkedin/test-butler
