  4. FYI:

  5. None
  6. None

  7. • it started as an experiment, now it’s become mature

    • it used to be all over the place, now it’s much more focused • it used to be adventurous, now it’s more conservative • now’s a great time to [re]try it!

  8. RSpec 2: more modular

  9. rspec

  10. rspec-core

  11. “provides the structure for RSpec code examples”

  12. examples and example groups

  13. spec runner

  14. metadata and filtering

  15. rspec-expectations

  16. “Provides a simple, readable API to express expected outcomes of

    a code example”

  17. rspec-mocks

  18. “RSpec’s ‘test double’ framework, with support for stubbing and mocking”

  19. stubs

  20. mocks

  21. rspec-core + rspec-expectations + rspec-mocks =

  22. RSpec 3: cleaner, smarter

  23. spring cleaning

  24. no more monkey patching

  25. verifying doubles

  26. composable matchers

  27. • mature • simpler, cleaner, more focused • world-class components

    • use the bits you like, ignore the bits you don’t like, bring your own other bits • conscientious, friendly, helpful maintainers

  28. thanks! @tomstuart / [email protected]
