Remotely with capistrano

You can also run your tests over capistrano, on a remote machine, assuming you have installed everything correctly on that machine, and deployed your changes to it.

If you run your tests over capistrano, you can get the same output as locally, with:

task :test do
  [some preparatory stuff]
  test_stream "rake parallel:spec 2>&1", :colorize => true
end

def test_stream(command, options = {})
  invoke_command(command) do |ch, stream, out| 
    trap("INT") { puts 'Interrupted'; exit 0; } 

    if options[:colorize]
      out.gsub!(/(?<= ^|[\.F*] ) \. (?= $|[\.F*] )/x, "\\033[32m.\\033[0m") # green
      out.gsub!(/(?<= ^|[\.F*] )  F (?= $|[\.F*] )/x, "\\033[31mF\\033[0m") # red
      out.gsub!(/(?<= ^|[\.F*] ) \* (?= $|[\.F*] )/x, "\\033[33m*\\033[0m") # orange
    end  

    print out
  end  
end

(this requires a decent network connection to the machine in question)
