Agile 2010 Hands-On Workshop, 8/9/2010 Abby Fichtner & Dawn Cannan You know how "Agile" works: programmers test drive their code via (A)TDD with testers automating much of the story tests. But how does it REALLY work? Do testers and programmers work together (YES!)? What does this interaction look like? In this hands-on demonstration, we'll walk you through how to drive quality on your projects by pairing testers and programmers. We'll use FitNesse to create effective story tests and keep them passing as the software evolves with each iteration. Bring a laptop and spend some time as a paired dev/test team!
