2012-10-26 RSpec::Formatter::Beep I hacked up a RSpec formatter, named RSpec::Formatter::Beep. https://github.com/kentaro/rspec-formatter-beep It beep when an example fails. It sleeps in 1 second to beep serially, so failure examples cause very slow results. It's so annoying that you're urged to fix tests as soon as possible. Have fun.
