The concept of automated acceptance testing (AAT) has had nearly a decade to mature. While it has their score of supporters, it has not been embraced as a silver bullet for software development.

By describing how they select the appropriate places to use FitNesse, and how they use it, other practitioners can apply this to their domain. This corresponds and adds to recent research.
