The specific question
I recently posted my test suite as a community wiki answer to a couple of questions that I worked on. Two contributions so far are:
The test suites use perl TAP, which is as close to universal as I know how to get ... easily. I made them community wiki to make it clear they are a common resource and encourage other people to contribute to them (I can dream). I had occasionally posted test suites as part of my answer in the past and decided that releasing them to the wild might be useful. Should I keep posting this specific type of test suite using this specific tool?
The general question
Do you think posting a test suite for questions with specific, non-trivial answers as a community wiki is a good idea? Why or why not? (The kind of open ended question I can only get away with in Meta.) If yes, is there a better tool for this than perl TAP?
Not the question
I am not proposing a requirement that every question include a test suite.
