I have been using autotest for 2 years, and it’s been great ! The first time I ran it I thought “This rocks !” and I have always been using it since …
Switching to guard was in fact very simple, It took about 15 minutes, a lot less than the time I had spent configuring or tweaking autotest. I simply added these to my Gemfile
gem 'guard' gem 'guard-rspec' gem 'guard-cucumber'
I ran the install steps, and everything was working ! It’s a shame I did not do the change earlier.
