1. Android Testing A Small Dive into
2. Android Testing Support Library Continuous Integration AWS Device Farm
3. Why is this hard?
4. Why is this hard? Many devices
5. Why is this hard? Many devices Many options
6. Android Test Strategy Harder, Better, Faster, Stronger • Strive for high coverage • Make it easy to get started and test • Run tests as much as possible • Get immediate test results • Understand and fix test results
7. Testing Fundamentals ApplicationPackage InstrumentationTestRunner TestPackage Test case classes Instrumentation JUnit Mock Objects
8. Testing Fundamentals Tests Run on the JVM Local unit tests Require Android Instrumentation tests app/src/test/java app/src/androidTest/java
9. Testing Support Library AndroidJUnitRunner JUnit 4-compatible test runner for Android Espresso Suitable for functional UI testing within an app UI Automator Suitable for cross-app functional UI testing across system and installed apps
10. Testing Support Library • JUnit Support @RunWith(AndroidJUnit4.class) • Access to instrumentation information (Context) • Test filtering @RequiresDevice, @SdkSuppress @SmallTest, @MediumTest, @LargeTest
11. 2015 Android Testing /**
 * A simple integration test which checks the validity of the DummyActivity
 */
 @RunWith(AndroidJUnit4.class)
 @LargeTest
 public class DummyBaseTest {
 
 @Rule
 public ActivityTestRule<DummyActivity> mActivityRule = new ActivityTestRule<>(DummyActivity.class);
 
 @Before
 public void setup() {
 // You might want to do something else here
 }
 
 @Test
 public void testContext() {
 assertThat(mActivityRule.getContext(), notNullValue());
 }
 
 @After
 public void teardown() {
 // You might want to do something else here
 } }
12. AWS Device Farm A step into
13. AWS Device Farm • Service that enables you to test your Android apps on real phones and tablets • Provide test reports containing high-level results, low-level logs, screenshot and performance data • Testing is performed in parallel
14. AWS Device Farm Upload your app Configure your tests Select a device pool and configure your tests Run
15. AWS Device Farm • AWS Device Farm plugin for Jenkins 
 (August 2015) • AWS Device Farm plugin for Android Studio (October 2015)
16. AWS Device Farm • Connect to the pre-prod or demo • Select a relevant device pool • Spoon integration • Jenkins credentials
17. Continuous Integration Getting around with
18. Continuous Integration for Android applications Automation Ship reliable apps Confidence
19. Continuous Integration for Android applications • Custom build logic • Manage dependencies, build variants, signing, testing Android Gradle plugin
