rspec ./spec/controllers/pages_controller_spec.rb:31 # PagesController GET 'contact' should have the right title
rspec ./spec/controllers/pages_controller_spec.rb:43 # PagesController GET 'about' should have the right title
rspec ./spec/controllers/pages_controller_spec.rb:57 # PagesController GET 'help' should have the right title'

end

    You could also use let (but then the specs need to use base_title rather than @base_title
