This is a Constraint - not a Kata!

Constraints can be applied to any given Kata to focus on specific techniques and / or practices. They are meant as an extreme perspective so you can clearly feel the difference to what you do usually.

How to Play

  • Work in pairs (should be a given anyway)
  • Person A only writes tests (test code only)
  • Person B only tries to get the tests to pass (production code only)
  • Both persons refactor when appropriate
  • Both are not allowed to communicate with each other except through code
    • No talking
    • No code comments
    • No magic Strings in code

The goal is to practice writing tests (and code as well) as expressive as possible.
