TDD Live

There is no better way to appreciate the effectiveness of Test Driven Development, that seeing it done real time. Today I spent a couple of hours with the good people at Focus, and was attempting to cover in a small 4 hour session:

  • Test Driven Development
  • Interface Based Programming
  • Dependency Inversion Principle - followed by Dependency Injection
  • Mock Objects

In such a short amount of time you can only hope to cover these topics at a pretty high (and quick) level.

The fun part, was coming up with a problem on the fly that I could use to demonstrate the values of Test Driven Development/Behavior Driven Development. By not going to the session with a prepared application, it allowed me to drive out a solution right before their eyes, and hopefully left them with a good impression as to the effectiveness that TDD can bring into an evolutionary design process.
