I’m doing a series of videos on TDD. The ultimate result will be a much more polished version with embedded slides, and such. But as a part of the development process, I’m creating scratch videos.

Much of what you see in these videos will be in the final versions, but those are far in the future relative to this work.

Hope you find them interesting.

Comments welcome.

Here is what is already available:

• Getting started
• Adding Operators

Next up:

• Removing violation of Open/Closed principle
• Removing duplication in operations with a combination of the Strategy pattern and the Template Method pattern
• Adding new operators after the removal of duplication.
• Reducing coupling by using the Abstract Factory pattern, Dependency Inversion and Dependency Injection
• Adding a few more operations
• Allowing the creation of complex “programs” or “macros” by using the Composite pattern – and avoiding Liskov Substitution Principle inherent in the GoF version of the pattern
• Driving the calculator via FitNesse + Slim

Anyway, that’s the plan. I’ll try to add each of these videos over the next few weeks.
