i have following in rails_helper.rb : rspec.configure |config| # ... config.before(:each, type: :controller) # end end i want define directories, something applicable (in case files under spec/controllers/api directory). any chance achieve that? you can use more specialized name rspec filter : rspec.configure |config| # ... config.before(:each, :subtype => :controllers_api) # end end and in rspec examples in spec/controllers/api , add metadata: rspec.describe "something", :subtype => :controllers_api end this something should run on examples having :subtype => :controllers_api metadata. did not use :type because there may other behavior defined it.
