  1. What’s new in Testing Gio Lodi, Mobile Infrastructure @ Automattic

    Melbourne CocoaHeads 2021/06/10  WWDC21
  2. • Xcode Cloud • async/await & test • XCTExpectFailure •

    Test Repetition • addTearDownBlock { }
  3. Xcode Cloud So that’s what they bough BuddyBuild for…

  4. None
  5. • Xcode Cloud docs homepage • Supports GitHub, GitHub Enterprise,

    Bitbucket Cloud, Bitbucket Server, GitLab, and GitLab self-managed instances • Environment Variables CI, CI_BUILD_ID, CI_XCODE_SCHEME, CI_TEST_PLAN, CI_PULL_REQUEST_NUMBER, … • Web Hooks – Note: You can configure up to five web hooks per Xcode Cloud product.
  6. Requirements for Using Xcode Cloud

  7. About Continuous Integration and Delivery with Xcode Cloud

  8. Review code and collaborate in Xcode

  22. Test Repetition More tools to avoid dealing with address flaky

    tests
  23. Diagnose unreliable code with test repetitions

  24. Diagnose unreliable code with test repetitions

  25. Diagnose unreliable code with test repetitions Until Failure

  26. Diagnose unreliable code with test repetitions Retry on Failure

  27. Diagnose unreliable code with test repetitions Up Until Maximum Repetition

  28. addTearDownBlock I couldn’t find a snarky remark for this one…

  29. None
  30. Test-Driven Development in Swift tddinswift.com

  31. One more thing…

  32. Vim key bindings So you’ll never be able to quite

  33. • Vim key bindings introduce “Modal Editing” • Normal mode

    – Verb + Movement + Subject • Insert mode • Visual mode • Limited support (for now? $%)
  34. Demo Time
