یک مجموعه یادداشت از نکات مهم TDD که در فروردین ماه ۹۹ در طول قرنطینه کذایی نوشته شد.

TDD is not a testing process it's a Design process

success is not getting green, success is the transition from red to green.

3 law

  • Write a failing test for a feature.
  • Write just enough code needed to pass the failing test. Quality no matter.
  • Refactor your code.

Why?

  • Short coding cycle => easier debugging.
  • Make your production code more readable and understandable.
  • Write test after write code is hard.
  • Write test after code leaves holes in test suit.
  • Make refactoring a pease of cake.we are confident about our code base and confidently refactor our code.

Challenges

  • How write test before code?

    • start developing on paper or you head not you code editor!
      after that you can easily write tests first.
  • it's wast of time!

    • TDD make debugging, refactoring, scaling easier and faster in the future.

There is noting good about driving fast in wrong way
