This document discusses the history and current approach to parallel iOS automation testing at Badoo. It describes moving from a single simulator approach that took 15 hours to run 500 tests to using multiple desktops in parallel, reducing the runtime to 2 hours with 10 simulators. It then discusses further optimizing to run multiple simulators on one desktop using Facebook's WebDriverAgent, reducing runtime to 90 minutes with 16 simulators. The approach combines Calabash and WebDriverAgent, termed "Facebash", allowing parallel testing while retaining Calabash features.

21. Let's Parallel!

22. Let's Parallel!
Blocker Issue:
- Calabash does not support Parallel run on 1 desktop

23. Let's Parallel
with multi-desktops!

24. https://techblog.badoo.com
Tim's talk at Badoo: "Parallel Calabash Testing on iOS"

25. II. Test Result: multi-desktops
~4 hours regression suite run time
5 Desktops

26. II. Test Result: multi-desktops
Mac PRO (24 cores)
~2 hours regression suite run time
10 Desktops

28. X Desktops: host limit reached

29. II. Clustering Hosts

30. II. Clustering Hosts
- Parallel run on multi (virtual) hosts
- Mac Pro and hosts: test suite - ~1h 30 min

31. II. Clustering Hosts
Issues:
- multi-desktops start up is Flaky
- simulators can get stuck

32. II. Clustering Hosts
Is it possible to automate multi-simulators on one desktop?

35. Profit:
- 7 simulators on single desktop
- More stable! more efficient!

36. II. Full Migration to FB UIA WDA
Issues:
- all tests have calabash code

37. II. Full Migration to FB UIA WDA
Issues:
- all tests have calabash code
- custom app backdoors

38. II. Full Migration to FB UIA WDA
Issues:
- all tests have calabash code
- custom app backdoors
- workarounds and other

39. II. Full Migration to FB UIA WDA
Full Migration Costs: ~x hours
Is it possible to do Fast Migration?

III. Summary: current approach

48. - easy to set up Parallel Run on 1 Desktop
- keep using of backdoors
- full access to internal AUT state
- cross iOS app automation
- iOS simulator control with FBSimCtl
- FB WDA supports Selenium protocol
- FB WDA independent of Calabash/Appium

III. Summary: PROs

49. - support framework parts: calabash server, FB WDA, fbsimctl, ...
- "poor" documentation
- using of mixed locator strategies
III. Summary: PROs and CONs

51. - Parallel Run in Headless Mode
- Simulator Start/Shutdown/Reset optimization
- Cold/Hot start iOS app with relogin
- record video per the each test in Parallel Run
Optimization

52. Thank you!
