running :
ruby -Itest test/functional/partners_controller_test.rb - should_create_partner runs all functional tests in partners_controller_test.rb
ruby -Itest test/functional/partners_controller_test.rb -n should_create_partner doesn't run anything at all
but it's clearly stated in the doc :
You can also run a particular test method from the test case by using the -n switch with the test method name. ruby -Itest test/unit/post_test.rb -n test_the_truth
is tr true ONLY for test/unit ???
thanks for feedback
