Test-driven Development (TDD)

TDD test-driven tdd development

Test-driven development (TDD) is a development technique where you must write a test that fails before you write new functional code.

Workflow

  1. Write a failing test
  2. Write code to make it pass.
  3. Repeat steps 1 and 2.
  4. Along the way, refactor aggressively.
  5. When you can’t think of any more tests, you must be done.
