It's a pretty common Java project, RESTful services and some MVC screens. We have been using Mockito for testing which is a first for me. My immediate impression is quite good. It's a nice tool and it allows some very clean testing of stuff that generally becomes quite messy.

Its claim to fame it that it is flexible. Its agnostic to ORM frameworks, JavaScript libraries or the templating engines. The core is pretty small and light. Support for all kinds of libraries is provided through plug-in(s).

It's time to get rid of this terminology problem. Ruby does NOT have meta classes. You can define them yourself, but it's not the same thing as what is commonly called the meta class.
