In a previous post, we mentioned a link to the first in a series of articles by Marc Clifton at The Code Project, a .NET resource site. Here are the links to all 5 of the articles in Marcâ€™s series. He starts out as a skeptic of the extreme programming philosophy, and decides that the only way to know is to apply it in a non-trivial way. Incredibly open minded about the approach, he addresses a lot of complex issues (refactoring of tests, entanglement in OO design, performance testing, and using scripts to create tests instead of code). This series includes C# specific details, and is very long (over 100 pages when printed).
