I found it . The problem was in the name. When I change it to 
current_cart.rb it worked fine.

The file in app/controllers/concerns is not named correctly - it declares a 
`CurrentCart` module, but is named `current_card.rb`. Fixing that makes all 
the tests pass.

Normally that problem occurs when you have a weird nesting or the naming of 
the controller compared to the test name is not correct as you can see in 
this 2 posts:
http://stackoverflow.com/questions/14267506/keep-getting-controller-is-nil-error
http://stackoverflow.com/questions/7743059/how-do-i-get-rid-of-controller-is-nil-error-in-my-tests

I only use rspec so I am not sure that this:
https://gist.github.com/andreorvalho/b306e186e888b1eccab5 

has the correct syntax. does the test for delete at the end fail too?
