git clone git://github.com/rspec/rspec-rails.git
cd rspec-rails
gem install bundler
bundle install --binstubs
Now you should be able to run any of:
bin/rake
bin/rake spec
bin/rake cucumber
rspec-rails runs its tests against many versions of Rails. To switch the
active version used for tests, use the thor version:use
command.
Examples:
thor version:use 3.2.8
thor version:use 3-2-stable
thor version:use master
The Gemfile includes the gems you'll need to be able to run specs. If you want to customize your dev enviroment with additional tools like guard or ruby-debug, add any additional gem declarations to Gemfile-custom (see Gemfile-custom.sample for some examples).
