Randomized Testing

randomizedtesting has some interesting options similar to StochUnit, however I like how it exposes the rand seed used to start the test for reproducability - I used to think about capturing the properties would be how I would like to preserve previous instances (what if the 2nd result was based on a random prior result?) Anyhow, looks like this has been there since 2012: https://web.archive.org/web/20120308222008/http://labs.carrotsearch.com/randomizedtesting.html Here is the presentation (live version).
