You want to add a new feature to a Ruby class using TDD. Which sequence correctly follows the TDD workflow?
ARefactor code, write test, write code
BWrite a failing test, write code to pass test, refactor code
CWrite code, write test, run test
DRun tests, write code, write test
Step-by-Step Solution
Solution:

  1. Step 1: Recall the TDD cycle steps

    TDD starts with writing a failing test to define behavior, then code to pass it, then refactor.

  2. Step 2: Match the sequence with the options

    Write a failing test, write code to pass test, refactor code correctly lists write failing test, write code, then refactor.

  3. Final Answer:

    Write a failing test, write code to pass test, refactor code -> Option B

  4. Quick Check:

    TDD cycle = Fail test, pass code, refactor [OK]
Quick Trick: TDD = Fail test, pass code, refactor [OK]
Common Mistakes:
  • Writing code before tests
  • Refactoring before passing tests
  • Running tests without writing them first
