Should I really test controllers?

I'm trying to get the best codecoverage/development time result

Currently I use rspec+shoulda to test my models and rspec+capybara to write my acceptance tests.

I tried writing a controller test for a simple crud but it kinda took too long and I got a confusing test in the end(my bad probably)

What`s the best pratice on controller testing with rspec?

Here is a gist on my test and my controller(one test does not pass yet):
