Niclas Hedhman commented on ZEST-18:
------------------------------------

>From Marcel (marrs);


Some research about it on-line, with the goal of a) understanding how it works and b) finding
a good Java implementation:
http://stackoverflow.com/questions/576901/have-you-used-quickcheck-in-a-real-project - especially
the first answer is valuable
There is a Scala implementation called “ScalaCheck” http://www.scalacheck.org/
There is a Java library that supports ScalaCheck/QuickCheck: https://github.com/functionaljava/functionaljava
/ http://www.functionaljava.org/
Another implementation is: https://bitbucket.org/blob79/quickcheck
Three Java ports are mentioned here: http://stackoverflow.com/questions/22712961/what-is-the-difference-between-agitar-and-quickcheck-property-based-testing
https://bitbucket.org/blob79/quickcheck (as found above)
http://www.jcheck.org/ (on SF, not updated for 2 years now, 0.1 version)
https://github.com/pholser/junit-quickcheck/ looks more promising.
Blog entries, still need to read them:

https://www.uni-marburg.de/fb12/ps/teaching/ss11/sw-analysis/quickcheck.pdf (german, states
that a combination of QuickCheck and Pex (C#) would be ideal)
https://weblogs.java.net/blog/editors/archives/2009/06/quickcheck_for.html
podcast: http://www.functionalgeekery.com/episode-10-paul-holser/ (the first half is more
interesting than the last, to me at least)
Another Java implementation: http://yaqc4j.sourceforge.net/
Guice based: https://code.google.com/p/guickcheck/ …code seems very basic
Similar, related links:
http://www.bodden.de/clara/ - Clara (CompiLe-time Approximation of Runtime Analyses) is a
novel research framework for the implementation of hybrid typestate analyses, which use static
analyses to partially evaluate runtime monitors for typestate properties. — has plenty of
docs on the site

>                 Key: ZEST-18
>                 URL: https://issues.apache.org/jira/browse/ZEST-18
>             Project: Zest
>          Issue Type: Improvement
>         Environment: Java 8
>            Reporter: Sandro Martini
>              Labels: java8, sandbox, test

> To better fix/identify problems in multi-thread execution contexts, verify if write (additional)
Unit Tests but with dedicated libraries (more specific than JUnit), like QuickCheck or one
of others similar (for example see even ScalaCheck).
> Note that usually many libraries for this require Java 8.
> As repository use Zest-sandbox (maybe in a feature branch), so it would be simpler to
evolve/integrate/remove later in Zest code base.
> For more info, see related thread in our dev mailing list.
