Reload Jasmine test suites in Firefox using MozRepl and this lovely gem.

Use it with watchr:

require 'jasmine-mozrepl'

extend Jasmine::MozRepl

watch('public/javascript/.*\.js') { do_reload }
watch('spec/javascripts/.*_spec\.js') { do_reload }

def do_reload
  system %{growlnotify -m "#{repl_reload(:echo_to_console => true)}" -t "Jasmine suite"}
end

do_reload

repl_reload options:

• :host is the host to connect to (default: 127.0.0.1)
• :port is the post to connect to (default: 4242)
• :jasmine_matcher is the address in the address bar to search for (default: "localhost:8888")
• :echo_to_console writes the success/failure message to the console in red/green (default: false)

repl_reload returns the success/failure count message from Jasmine so you can use it as you wish.
