Agile Decompiled: Test Driven Development

Unit testing pre-dates TDD but TDD reverses the idea of testing your units of code and says you should start with a test, and that test should fail, and then you should write the code to make the test pass.The obvious advantage to this is that when you subsequently make a change you can see if the change has broken anything else in the system, which will give you greater confidence in your code.
