Lambda the Ultimate

AutoTest is a testing too for Eiffel akin to QuickCheck for Haskell, which automates testing of code based on contract based specifications of functions. While AutoTest is still in development, it is also more ambitious than QuickCheck, seeking to provide a single push-button approach to testing with multiple pluggable strategies for generating test data. A recent talk discusses in more detail some of the more advanced aspects of where AutoTest is going. Most importantly AutoTest has proved to be practical, having already found a number of bugs in Eiffel's base libraries!
