Problems and solutions for TDD labs.

Currently we have the following labs:

• test-leapyear - Leap Year
• test-income-tax - Income tax calculator

How To Test-Drive

• Develop iteratively
• Follow the TDD cycle of RED, GREEN, REFACTOR
  • RED - Think of one simple example of how the system should be used
  • GREEN - Add just enough code to make the test pass
  • REFACTOR - Make the system code as well as tests easier to change.
• If working in a group or pairs, it's common for each participant to do a full TDD cycle, rotating after a failing test has been written.
