Test Driven Development

When I first heard about TDD, the idea seemed to be pretty simple. Just by doing a little word swizzling, obviously TDD is when you have tests that drive your software development.

The TDD stages:

• First the developer writes one tests.
• The developer then runs those tests and (obviously) they fail because none of those features are actually implemented.
• Next the developer actually implements those tests in code.
• If the developer writes their code well, then the in next stage they will see that their tests pass.
• The developer can then refactor their code, refactor by patterns and with focus on DDD.
