1. UI TESTING for Android Developers Jana Moudrá @Janamou +JanaMoudra
2. Eh, tests?
3. Motivation
4. I tested the app myself...
5. Not repeatable Time consuming Error-prone Manual Testing
6. WE WANT TO AUTOMATE
7. UI testing lets you ensure that your app meets its functional requirements and achieves a high standard of quality... Source: developer.android.com/training/testing/ui-testing/index.html
8. ANDROID!
9. UI Automator vs Espresso Simulates user interactions UI Testing on Android
10. src/androidTest/java folder JUnit 4 tests Runs on same device as app Android tests how to
11. UI AUTOMATOR
12. For many apps System apps No app source code Interacts with visible elements UI Automator
13. Android 4.3 (18) or higher Works with AndroidJUnitRunner UI Automator requirements
14. android { defaultConfig { testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } } UI Automator setup build.gradle
15. dependencies { androidTestCompile 'com.android.support.test:runner:0.5' androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.2' } UI Automator setup build.gradle
16. android:contentDescription for ImageView etc. android:hint for EditText UI Automator accessibility
17. UI Automator Viewer <android-sdk>/tools/
18. assertEquals(hiButton.getText(), "Hi"); UI Automator asserts
19. UiDevice UiSelector UiObject UiCollection UiScrollable Configurator UI Automator API
20. ESPRESSO
21. For a single app Not for system apps App source code Espresso
22. Android 2.2 (8) or higher Works with AndroidJUnitRunner Espresso requirements
23. android { defaultConfig { testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } } Espresso setup build.gradle
24. dependencies { androidTestCompile 'com.android.support.test:runner:0.5' androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1' } Espresso setup build.gradle
25. For Settings/Developer Options: Window animation scale Transition animation scale Animator duration scale Turn off Animations
26. ActivityTestRule ViewMatchers ViewActions ViewAssertions Espresso API
27. Espresso Intents - extension for validation and mocking of Intents Espresso Contrib - additional features for great tests (RecyclerView) Even more Espresso
28. WHICH SHOULD I USE?
29. Black box vs White box Multiple apps vs Single app Without source code vs With source code UI Automator vs Espresso
30. Use gestures Retrieve attributes Set text No manipulation What can I do with UI tests?
31. Monkey Espresso Test Recorder Firebase Test Lab Other tools
32. Robolectric Appium Calabash Selendroid Other libraries
33. NO MORE UNTESTED APPS! Jana Moudrá @Janamou +JanaMoudra
