6. Mobile UI testing is hard and slow
10. Setup
11. Environment Setup (your machine) Install the latest version of the Appium: • Desktop Application • NPM Package
13. Environment Setup (your machine) Install and verify dependencies
14. Environment Setup (your machine) • Make sure that you have a recent version of Ruby installed • Install the gem bundler
15. Your machine is ready to run UI tests
16. Project Setup (the application you want to test) Add a Gemfile in the root directory of the mobile app project
17. Project Setup (the application you want to test) Create “spec” sub-directories in the root of the mobile app project
18. Project Setup (the application you want to test)
19. Project Setup (the application you want to test)
20. Both your machine and project are ready to run UI tests
21. So it’s time to write some tests
22. “In a well-test application, tests remain the code without tests” Noel Rappin
24. Ruby FTW: easy-to-read and maintainable tests Write tests like stories using clearly named and shared helpers
25. Find view elements faster 1. Class name 2. Accessibility identifier 3. XPath
26. Debugging - Pry
27. Debugging - Take Screenshots => Great on the CI server
28. “Faster” Test Suites • Do NOT use sleep in tests • Group test by criticality
29. Mobile UI testing is still hard and slow
30. But... Appium and RSpec provide • Simple setup • Large ecosystem • Stable API • Fast and very active development following mobile OSes releases • One tool for all platforms
