Traversing the Test Pyramid in Android

During our, me and Dubinsky, 18 months of experience of Android development, we have evolved in adopting strategy for testing Android application. A small glimpse of how we did unit and functional testing for an hybrid Android application.

1. Traversing Test Pyramid for Android development Dubinsky Dee Soares Jigish Chawda
2. Agenda !   Test Pyramid !   Why TDD? !   Approaches of unit testing. !   Problems and solutions for unit testing. !   Sample tests. !   Functional Testing – overview. !   Various frameworks and approaches followed. !   Functional Test - demo. !   Continuous Integration
3. Test Pyramid Functional Tests Integration Tests Unit Tests
4. Why Testing for Android? !   Stable and better quality applications. !   Apps are as important as the websites. !   Ubiquitous.
5. Overview of Unit Testing in Android Unit Test Business logic View validations Behavior
6. Android Test Framework - Problems…. ACTIVITY POJO •  Low test coverage •  UI interactions & data binding untested. •  Framework runs on DVM •  Time consuming
7. How can we solve these problems ? ACTIVITY POJO Virtual Machine JVM .class RED GREEN REFACTOR
8. Let’s have a look at a few tests.
9. Overview of Functional Testing !   Actual Application !   Business Use Case !   Visual Appearance !   Realistic Mobile Challenges !   Fragmentation !   Release
10. Functional Testing Tool Expectation !   Business language !   Expressive !   Keep up with times !   Robust !   Realism !   CI Support
11. Functional Test : Approaches !   Instrumented technique !   Non- Instrumented technique
12. Calabash Robotium Functional Testing : Instrumented Approach Android Testing Framework •  DSL •  Flexible APIs •  WebView support. •  Support iOS & Android •  Continuous Integration
13. A Demo - Calabash-android
14. Functional Testing : Non Instrumentation !   Not restricted to one App !   Custom Components !   External Interactions !   Hardware Drivers Tools !   UI Automator, HoneyDew, Appium
15. Continuous Integration CI BOX Pass Fail
