I have accepted an invitation to speak at GSP Developers  in March. My topic will be Test Driven Design. I will focus on how practicing TDD changes the overall design of your software.

I think my strategy should be:

Give a brief overview of TDD.

Demonstrate writing a simple function TDD style.

Discuss what is meant by “testable” code, meaning how testable code relates to the SOLID design principles.

Give a brief overview of the available TDD tools for .NET.

Any advice for a first-time speaker?
