4. Our journey Automation principles Scope definition Architecture Tools and frameworks Continuous testing
5. Mobile Engineers build the app Test environment Test Engineers check the functionality
6. Mobile Engineers build the app Test environment Tests Passed
7. CHALLENGE
8. Testing becomes more time consuming and slows down the release process
9. Number of mobile devices and operating systems is increasing over time
11. AUTOMATION
12. INITIAL ASSUMPTIONS Automation as a silver bullet Automate all the things Automation is testing The best tool will solve all problems Automation is a tester’s job
13. Principles
14. Principles A test executed once it’s not a test anymore - it’s a check
15. Principles If you need to repeat a check, automate it
16. Principles Effective team collaboration Testing approach and scope Evaluate the right tools Continuous learning and improvements
17. Test Engineers Mobile Engineers
18. Mobile Engineering
19. Scope UNIT TESTS UI INTEGRATION/COMPONENT TESTS AUTOMATED E2E TESTS EXPLORATORY TESTING
20. Scope UI INTEGRATION/COMPONENT TESTS - Easy to implement - No external dependencies - API, 3rd party - Less prone to flakiness - Does not require application file - Mocking - Execution on real devices and simulators
21. Scope AUTOMATED E2E TESTS - User journey - HTTP connections - Prone to flakiness - Requires application file - Execution on real devices and simulators
22. ARCHITECTURE
23. Architecture Domain Test Data Infrastructure Devices Reporting Integration
24. Architecture Domain Test structure Test suites
25. Architecture Test Data Configurable static test data Dynamic test data - API helpers IT’S ALSO AUTOMATION
26. Architecture Infrastructure Test Environments Mockable Limited Production Environment IT’S ALSO AUTOMATION
27. Architecture Devices In house devices Devices on Cloud
28. Architecture Integration Manual build execution Continuous integration servers IT’S ALSO AUTOMATION
29. Architecture Reporting HTML reporting XML reporting Data Visualisation & Monitoring IT’S ALSO AUTOMATION
30. Capabilities of a specific tool Tool meets specific needs. Tool doesn’t seem to provide full test coverage Tool costs exceed the team budget Tools
31. Tools and frameworks https://dzone.com/articles/mobile-test-automation-framework-trends
32. Tools UI INTEGRATION/COMPONENT TESTS AUTOMATED E2E TESTS
33. SauceLabs devices Jenkins + Docker Chat channel Appium + Java + TestNG + PageObject Model Framework Reporting dashboard
34. SauceLabs devices Jenkins + Docker Chat channel Espresso + XCUITest Framework Reporting dashboard
35. CONTINUOUS TESTING
36. Continuous testing Pull request
38. Continuous testing takeaways • Layered test architecture • Regression rate reduced • Mobile automation in the development scope • Extensive access to cloud devices and OS versions • Team ownership • Leverage tools • Constant and fast build feedbacks UNIT TESTS UI INTEGRATION/COMPONENT TESTS AUTOMATED E2E TESTS EXPLORATORY TESTING
