Assuming this is a controller spec, you can reference the controller
via the `controller` method (courtesy of
ActionController::TestCase::Behavior [1][2][3]):
shared_examples "omg" do
it "gets something" do
Something.stubs(:new).returns "lol"
get :show
controller.something.should == "lol"
end
end
describe FooController do
it_behaves_like "omg"
end
