Wrapper over flexmock, it helps you in mocking active record objects, especially those with associated data.

As of 0.7.0, Jim Weirich extended flexmock to support easier mocking of AR objects: http://onestepback.org/software/flexmock/files/doc/releases/flexmock-070_rdoc.html.
Jim has done an excellent job. I recommend to use his updated flexmock instead.
