Test runner for TDD running in background and talking to you on MacBook combined with a small Guardfile - awesome tool in the train, no need to see the terminal

Guardfile

notification :off

guard 'shell' do
  watch(/^myproject.*.py$/) {|m| `./testrun.sh` }
end

testrun.sh

#!/bin/bash                                                                                                         

say "Running tests"

if ./manage.py test --noinput >&2
then
    say "Tests are passing"
else
    say "This shit is failing!"
fi

This is the best thing I ever saw! We should have this after deployment!
