The Ultimate Tester and the Lazy Implementor

One of the hardest parts about testing is coming up with the right tests. This is a simple pairing game based on test-driven development to help you practice writing better tests.

The idea is simple.

The Ultimate Tester's goal is to trick the Lazy Implementor into writing good code by writing good tests.

The Lazy Implementor's goal is to make the tests pass by writing a function with as little code as possible that does not actually solve the whole problem...

Here are some ground rules:

• The tester can only write one test at a time
• Each test written must fail before the implementor's turn begins
• The implementor's turn continues until all tests pass
• If the implementor's function exceeds 17 lines, the code must be refactored (Feel free to create functions above the module.exports)

Check out the example test and implementation files in the example folder to see how something like this might proceed.

How to Play

1. Pair Up.
2. Assign Roles (Implementor and Tester).
3. Set a timer for 25 minutes.
4. Begin Game.
5. After timer is up, or after the implementor can no longer trick the tester:

• Swap Roles.
• Choose to continue the same problem, or choose a new one.

6. Repeat.
