What

• TDD: Fail, Pass, Repeat
• Types
  • Unit - one single component/function in isolation
  • Integration - multiple coordinating components
  • Feature: User feature
  • Acceptance: Collection of features
  • End to End : All of it in a user/consumer experience
  • Regression: Did I do that?
• SEAT: Setup, Execute, Assert, Teardown
• Mocks & Stubs
  • Fake it till you make it
  • Don’t mess with other test’s data

Why

• Find Early
• Update with confidence
• Think through edge cases
• Don’t trust your future self
• Think about business requirements and make them work
• Think about exceptions and edge cases and make them work/fail gracefully

How

• Initial simple hello ‘name’
  • Setup test
  • Add watcher
  • Change test to have comma
  • Reload
  • Handle Exceptions?
• Weather
  • Address -> Zipcode -> weather
  • Geocode Address
  • Handle Weather response and unknown
  • Handle Address unknown/error, 2 results? hot/cold/rain
  • Travis
