How to run a single shoulda context test in ruby Test::Unit framework

Question

I can typically test a regular Test::Unit method using the following commandline syntax for a method "delete_user_test":

ruby functional/user_controller_test.rb -n delete_user_test 

Now when I'm using the shoulda plugin with Test::Unit I try to use the same technique as follows:

...  context "Deleting a User" do   should "remove user from user table" do     ...   end end 

Then I try to run the single test as follows:

ruby functional/user_controller_test.rb -n "test: Deleting a User should remove user from user table" 

This doesn't work. Does anyone know how I can run a single context tests using shoulda and Test::Unit. I have a couple of different test in one test file and I want to only run the one using TDD without having to wait for all tests to run.

Answer 1

This works for me:

ruby functional/user_controller_test.rb -n "/Deleting a User/" 

Just put some reasonably long string from your context name into the regular expression.

Answer 2

Using the full name of the test with a space at the end seems to work too:

ruby -Itest       functional/user_controller_test.rb       -n "test: Deleting a user should remove user from user table. "
