"As a black box tester working on a variety of development projects, I was often approached by developers who were trying out test-driven development and wanted to learn more about testing. To show them how I worked, I involved them in pair testing, a technique in which two people test an application at the same computer. Interestingly enough, the developers taught me as much as I taught them."
