Test Driven Development (or Design) is a software engineering paradigm where one starts off with writing a failing test (suite) and from there tries to implement code to ultimately make the test succeed.

It is mainly divided into three styles:
- [[Detroit-style TDD]]
- [[London-style TDD]]
- [[Discovery Testing]]
