The rspec:install generator creates a .rspec file, which tells RSpec to
tell Autotest that you're using RSpec. You'll also need to add the ZenTest and
autotest-rails gems to your Gemfile:
gem "ZenTest", "~> 4.4.2"
gem "autotest-rails", "~> 4.1.0"
If all of the gems in your Gemfile are installed in system gems, you can just type
autotest
If Bundler is managing any gems for you directly (i.e. you've got :git or
:path attributes in the Gemfile), however, you may need to run
bundle exec autotest
If you do, you require Autotest's bundler plugin in a .autotest file in the
project root directory or your home directory:
require "autotest/bundler"
Now you can just type autotest, it should prefix the generated shell command
with bundle exec.
