RSpec: Where to put shared example groups

Shared example groups Archive are a useful RSpec feature. Unfortunately the default directory structure generated by rspec-rails has no obvious place to put them.

I recommend storing them like this:

Copy
spec/models/shared_examples/foo.rb
spec/models/shared_examples/bar.rb
spec/models/shared_examples/baz.rb
spec/controllers/shared_examples/foo.rb
spec/controllers/shared_examples/bar.rb
spec/controllers/shared_examples/baz.rb

To make those shared examples available to all specs, put the following into your spec_helper.rb (for rails 4 in rails_helper.rb), above the RSpec.configure block:

Copy
Dir[Rails.root.join("spec/models/shared_examples/**/*.rb")].each {|f| require f}
Dir[Rails.root.join("spec/controllers/shared_examples/**/*.rb")].each {|f| require f}

Make sure you don't call your examples files like ..._spec.rb, else RSpec will believe they're actual spec files and require them.
