TDD/Unit Tests/FIRST

FIRST properties of Unit Tests. http://agileinaflash.blogspot.com/2009/02/red-green-refactor.html

• Fast: unit test must be fast - A software project will eventually have tens of thousands of unit tests, and team members need to run them all every minute or so without guilt.
• Isolated: Tests isolate failures. A good unit test has a laser-tight focus on a single effect or decision. Good tests interferes with no other tests in any way. They impose their initial state without aid from other tests. They clean up after themselves.
• Repeatable: Tests must be able to be run repeatedly without intervention.
• Self-validating: Tests are pass-fail.
• Timely: Tests are written at the right time, immediately before the code that makes the tests pass.

• Red: Failed test
• Green: Passed test
• Refactor: Clean up. Remove code. make into smaller units. performance.
