یادداشت هایی از TDD

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
