[racket-dev] Racktest was: OMG the thread that will never die about testing

Climbing into this conversation late (Goodness, what a time for me to go out of sight of the internet...) so I haven't delved into all of the proposals and arguments that have been flowing around. 

I first want to point out (if it hasn't been discussed already) that the test-engine library was actually developed to support multiple different testing front ends (originally Java's and Scheme's, but it was meant to be flexible). While it doesn't do this as robustly well as I'd like, some of the structures and support I've noticed being discussed are possibly lurking within the implementation. 
I'd certainly be happy to assist in efforts to make the test-engine more robust for supporting other testing packages integrated with DrRacket and/or the textual variant.

I'm partially making the library more flexible myself at the moment because I've been trying to implement some of my more recent research on testing into Racket (System Tests from Unit Tests, UCam techreport and soon to be ICFP submission), that I'd like to make available once it's ready and have integrated with the test engine (and therefore DrRacket).
