2. THEORY VS PRACTICE
3. THEORY
4. TAKING OVER AN EXISTING APP
5. TAKING OVER AN EXISTING APP WITH NO TESTS
17. DOES THIS WORK FOR THE USER?
18. ADD A SCAFFOLDING OF UI TESTS AROUND YOUR APP
19. ! BEFORE YOU START DEMOLITION ON THE EXISTING CODE
20. UNIT TESTS VS UI TESTS
21. UNIT TESTS
22. UI TESTS
23. SNAPSHOT TESTS VS INTEGRATION TESTS
25. INTEGRATION TESTING
26. INTEGRATION TESTING
27. PRACTICE
28. XCUI VS KIF
29. XCUI TESTING XCODE 7 / IOS 9+ / OS 10.11+
30. APPLE BUILT IT
31. APPLE BUILT IT TO FIT UIAUTOMATION
32. ! BLACK-BOX STYLE TESTS TEST RECORDER
33. TESTS IN ONE PROCESS APP IN ANOTHER PROCESS
34. ! MOCKING IS IMPOSSIBLE TEST CODE IN YOUR APPLICATION
35. ! MOCKING IS IMPOSSIBLE TEST CODE IN YOUR APPLICATION
37. KIF TESTING FACILITATING FUTURAMA JOKES SINCE JUNE 2011
38. ! EASY MOCKING BACKWARDS-COMPATIBLE OPEN-SOURCE CODE
39. ! EASY MOCKING BACKWARDS-COMPATIBLE OPEN-SOURCE CODE
40. ! USES PRIVATE APIS LOTS OF CRUFT FOR BACKWARDS COMPATIBILITY INCONSISTENT (ESP. ON CI SERVERS)
41. ! USES PRIVATE APIS LOTS OF CRUFT FOR BACKWARDS COMPATIBILITY INCONSISTENT (ESP. ON CI SERVERS)
42. WHAT DO I USE?
43. SIMPLE APPS: XCUI COMPLEX APPS: KIF
44. SIMPLE APPS: XCUI COMPLEX APPS: KIF * AS OF A MONTH BEFORE WWDC 2016
45. WHAT DO I TEST NEXT?
46. CODE COVERAGE YOUR TESTING ASSISTANT
47. CODE COVERAGE YOUR TESTING ASSISTANT
53. REMINDER
54. ROBOTS ARE AWESOME, BUT THEY CANNOT REPLACE HUMAN TESTERS
56. OBLIGATORY SUMMARY SLIDE! > UI Tests give you user-centric feedback > UI Tests let you refactor confidently > Use XCUI for simple, KIF for complex stuff > Use Code Coverage to guide your testing > ! + " = ######
