The checks are stored separately in a JSON file. + +Other approaches to this tend to use either a precompiler, a replacement compiler, or Java's reflection capability, but our goal was to find a design pattern that would add the checks in a language agnostic way. + +(Even then, there is prior art, specifically that of Brian A. Malloy at Clemson University. For more information, see #19, #26, and #40 [here](http://www.cs.clemson.edu/~malloy/papers/papers.html). Our work differs by attempting to support abstract and generic classes, as well as checks involving fields that don't already have accessor methods.) + +Although this plugin is largely a proof-of-concept tool in support of the design pattern, it's quite functional as-is. The generated classes can be used as drop-in replacements in unit testing, and if an invariant should fail to hold, the tester is told which one failed, during which method call, and during which test. That makes debugging much easier, as we discovered when it found some bugs of our own! </pre>Anonymous CowardSat, 18 Jun 2011 18:47:14 -0000https://sourceforge.net82034827b71ad9f188028cef6e0bfd7d9663ea3bhttps://sourceforge.net/p/checkinv/home/Home/Welcome to your wiki!
