Out of curiosity, does someone know if QuickCheck was the first test framework working through test by properties associated with random generation or if it drew the idea from something else?

Because the idea has be retaken by a lot of frameworks in several languages (seehttp://en.wikipedia.org/wiki/Quickcheck), but I can't find what was QuickCheck inspiration.

How about reading the original paper introducing QuickCheck? If the authors drew inspiration from elsewhere, the paper is for sure where they would tell you, first hand. :-) Best, Janis. -- Jun.-Prof. Dr. Janis Voigtländer http://www.iai.uni-bonn.de/~jv/

Yes ^^ but I can't find this paper, Koen Claessen website doesn't mention it and the link on the page http://www.haskell.org/haskellwiki/Introduction_to_QuickCheck is dead. 2012/6/1 Janis Voigtländer

See the Further Reading section on the wikipedia page you provided (http://en.wikipedia.org/wiki/Quickcheck), not all links are dead. 2012/6/1 Yves Parès :

Yes, it's that one, the first Quickcheck paper, thanks. The link on the wikipedia page is also dead. 2012/6/1 Ivan Perez

As far as I'm aware: - property-based testing wasn't new (think 'assertions' and then think 'branch coverage') - randomly generated test cases weren't new (look up 'fuzz testing') and there were tools like DGL to generate random test cases in a controlled sort of way + the *type-driven* approach making it nearly effortless to test a property once stated was new. As soon as I met QuickCheck, I knew what it was for and how to use it. The truly astonishing thing was how _easy_ it was to get started. It is true that other languages have since picked up the idea (like Erlang), but without Haskell's type system to drive it, it's not nearly so easy to get started. The Haskell implementation of QuickCheck was a couple of pages of code. The first Erlang implementation is a serious proprietary product.
