Rails

• empty? vs blank?

  .empty? # will through an error if it's null
  .blank? # will get false if it's null, so if you are going to check if a value is null, or empty string, use blank 
  instead
  

• FactoryGirl

AntiTesting

• Test the right function
  • Critical code - breaks often, gets most of new features, big impact on application users
  • Core code - breaks sometimes, gets few new features, medium impact on the application users
  • Other code - rarely changes, rarely gets new features , has minimal impact on application users.
• What's really matter than test coverage:
  • PDWT (Percent of Developers who Write Tests)
  • PBCNT (Percent of Bugs that Create New tests).
  • PTVB (Percent of Tests that Verify Behavior and not implementation)
  • PTD (Percent of Tests that are Deterministic to total tests).
