Test Driven Development

From Making Good Software

Lots of people confuse “test first methodologies” with TDD, it is very common to listen comments like “TDD is just about writing your tests first”, which are completely wrong, these kind of affirmations are not describing TDD at all, they are talking about test first development.

The main reason for confusing TDD and test first development is its own name: “test driven development”. If someone that doesn’t know about TDD would had to guess based on the name what TDD is, would probably guess that is just a test first methodology. But is not!

TDD as invented by Kent Beck, (who also invented Xtreme programming and Junit), goes beyond that. In the core of TDD there is a process to follow, which makes it already different from a simple test first approach.
