  I must hunt down and learn to use a QuickCheck-like library for my language.

  If I can't find one, I should write one.

So what's the (best) equivalent of QuickCheck in Ruby? In other languages?

For Ruby: http://rushcheck.rubyforge.org/about.html

Check out the citations on http://en.wikipedia.org/wiki/QuickCheck for QuickChecks in other languages.

Scala has scala check: http://code.google.com/p/scalacheck/

Ruby, because of non static types, can't be as magical, but people have given their best: https://github.com/IKEGAMIDaisuke/rushcheck

I'm not sure about one that can generate arbitrary data, but Heckle[0] will break your Ruby tests in extravagant ways.

A quick google search returned this:

* qc for python (http://dan.bravender.us/2009/6/21/Simple_Quickcheck_implemen...)

* QuickCheck Wikipedia page with links ot implementation for many languages (http://en.wikipedia.org/wiki/QuickCheck)

Personally I am looking forward to trying out qc for python. Has anyone here used it before?

Go has a QuickCheck-like package distributed with it. It's under testing/quick.

For C# I in fact thought of what is in the above quote and wrote my own: https://github.com/ane/DotCheck

It's not yet very advanced (sometimes the library is a bit messy), but it provides the basic QuickCheck functionality.

There's qc [1] for Javascript.

rushcheck is a bit moribund, or was last time i checked. https://github.com/hayeah/rantly is pretty nice.

For Perl it's a module called Test::LectroTest

Very cool, I didn't realize there was a generic version of Pex (the unit test generator for C#). Now if only I could figure out some way to unit test drivers...
