Exceptionist - Force your application to crash

Want to force your Rails 3 application to respond with a certain HTTP status code? Just call

http://my.app.com/fire/500

to let the application crash, or call

http://my.app.com/fire/412

for a nice'n'nifty precondition failed.

Installation

Simply install via

$ gem install exceptionist

or when using Bundler, add the line

# Gemfile
gem 'exceptionist'

to your Gemfile and call

$ bundle install

Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
