2. Preamble: UI vs. Unit Tests
3. UI Testing Options
4. KIF
5. XCUI

7. So which framework should you use?
9. You can use this technique with any or every UI testing framework
10. ! ! ! ! ! ! ! ! ! ROBOTS ! ! ! ! ! ! ! ! !
15. Sample Code https://github.com/designatednerd/GoCubs

18. KIF XCUI
19. With DRY refactoring:
21. With Robots:
22. Separate the What from the how
23. More Composable test code
27. ROBOTS * - sometimes known as controllers
28. How do we steal adapt this idea for Swift?
29. Protocols!

41. Some gotchas with multiple variations
43. Subclassing XCTest directly: ✅ class GoCubsXCUITests: XCTestCase { ❌ class GoCubsKIFTests: KIFTestCase { ✅ class GoCubsEarlGreyTests: XCTestCase {
44. MOAR PROTOCOLS!
46. Using the protocol instead: !!!!!!!!!!!!!!!!!!!!!!!!!!!! class GoCubsXCUITests: XCTestCase, RobotTests { class GoCubsKIFTests: KIFTestCase, RobotTests { class GoCubsEarlGreyTests: XCTestCase, RobotTests { !!!!!!!!!!!!!!!!!!!!!!!!!!!!
50. Using @testable import:
51. Using @testable import: ❌ class GoCubsXCUITests: XCTestCase, RobotTests { ✅ class GoCubsKIFTests: KIFTestCase, RobotTests { ✅ class GoCubsEarlGreyTests: XCTestCase, RobotTests {
54. Obligatory Summary Slide!
55. Obligatory Summary Slide! Robots will help you: - Separate what what from how
56. Obligatory Summary Slide! Robots will help you: - Separate what what from how - Keep your tests readable
57. Obligatory Summary Slide! Robots will help you: - Separate what what from how - Keep your tests readable - Swap out the underlying implementation
58. Obligatory Summary Slide! Robots will help you: - Separate what what from how - Keep your tests readable - Swap out the underlying implementation FREE ADVICE:
59. Obligatory Summary Slide! Robots will help you: - Separate what what from how - Keep your tests readable - Swap out the underlying implementation FREE ADVICE: - Giving techniques cool names makes it way more likely people will steal use them.
