Functional test default methods

Given a route "resources :orders," why does the following (generated) functional test using a GET request work? Should it?

  # test/functional/orders_controller_test.rb   test "should get create" do     get :create # create action supports request method other than POST?     assert_response :success   end

It isn't really a problem, I'm just curious if I'm missing something.

If I am interpreting the output from rake routes correctly then an attempt to run a create action with GET will actually call the index action, so it should succeed.
