In the past few years when giving trainings and presentations on the topic Agile Testing, the question on who is an agile tester kept coming back. Therefore, I've decided to set up a checklist on the topic. It's based on personal experience, research, and remarks from previous presentations I did. When going through this list with "potential agile testers," many of them realize they are not agile testers, but sometimes just unorganized, chaotic testers.
