At the Forge - Testing Rails Applications with Shoulda
The home page for Shoulda is thoughtbot.com/projects/shoulda. The documentation here is a good starting point, but you probably will need to play with it a bit to get the hang of things. Even the small problem I described above, in testing the minimum and maximum ages for a person, showed that you still might need to poke through the documentation to understand things fully.
A PDF cheat sheet for Shoulda is at kylebanker.com/assets/content/2008/shoulda_cheat_sheet.pdf, and the popular cheat sheet program for Ruby programmers also has an entry: cheat.errtheblog.com/s/shoulda.
The following are a few interesting blog posts about Shoulda that also can provide some useful ideas: pragdave.blogs.pragprog.com/pragdave/2008/04/shoulda-used-th.html, giantrobots.thoughtbot.com/2009/2/3/speculating-with-shoulda and www.alexjsharp.com/2008/10/15/shoulda-painless-unit-testing.
