Поговорим о тестирование Android приложений при помощи Calabash, Robolectrick, Spock и Junit. Как правильно применять BDD на вашем проекте. Обсудим настройку настройку билд сервера и процесса Continious Delivery в андроид экосистеме.

1. CRACKING ANDROID APP
Sergei Mokienko

2. ABOUT ME
3+ Android development
5+ в IT
Witness of 90% coverage
Agile addict

3. AGENDA
Do tests exist on mobile projects ?
Can business write tests ?
How to face release dates without red eyes ?

4. WHEN DO WE NEED TESTS ?
•When we are going to support codebase for a long time
•When the whole team agrees on writing tests
•When tests gives real value but not statistics
•When we are developing API for external services

5. Unit testing

6. + +
Clean java way
•Works with clean java (less Android
dependencies is best)
•Tests running on local JVM
•Android studio 1.0 + Gradle plugin 1.1.0+
supports running from IDE

7. Setting up Android Studio
Create folder test/java under app/src
Create test suit

8. Mocking Android
+
•Helps with unit tests for logic that is tightly coupled wi
Android SDK
•We can still run tests on local VM
• Nice assertions

10. Integration tests

11. Espresso
•No unnecessary waits for UI thread events
•Officially supported by Google
•Works with Android Instrumentation
•Harmcrest assertions
•JUnit 4

13. What Espresso can do ?
Work with views
Work with adapter views

14. Check intents

15. Spoon
•Running tests on several devices simultaneously
•Taking screen shots
•Great reports
•Run specific tests on multiple devices
•Choose device where you want tests to run

16. Add grade plugin for spoon
Add plugin to your app module
Run spoon task gradle spoon

17. BDD

18. What BDD is ?
•Behavior Driven Development
•Usage of DSL (Domain Specific Languages)
•Clear implementation understanding
•More tests approved by management
•High product owner involvement
•Lots of tests =)

19. Acceptance test
Formula
As a [role]
I want [feature]
so that [benefit]
Acceptance criteria
Formula
Given [initial context]
when [event occurs]
then [ensure some outcomes]

20. Calabash Android
•Cucumber wrapper
•Integrates with Xamarin cloud
•Cross-platform
•Flexible
•Large collection of predefined steps
•Continuous Integration support

21. Cucumber
•Gherkin
•Scenarios
•Feature definitions
•Step definitions

22. Cucumber + Ruby + Robotium
=

23. Calabash as is

24. Continuous Integration

25. Why ?
•Fast integration bug allocation
•No panic when release happens
•No merges with bug happens
•Every body knows where they can find build
•Enforces discepline
•Automatic metrics generation

26. How ?

27. Questions ?
