Hello,- got a question regarding strange behavior by rcov. I have a gyms\_controller.rb with the usual group of CRUD methods. Each one of them is being tested in the gyms\_controller\_test.rb: $ ruby test/functional/gyms\_controller\_test.rb Loaded suite test/functional/gyms\_controller\_test Started … Finished in 5.985611 seconds. 9 tests, 20 assertions, 0 failures, 0 errors So far, so good. Then, I’ve installed rcov and the majority of the code that is being tested is marked as not covered by the test. In particular, the fairly trivial test for the index action: 5 # GET /gyms 6 # GET /gyms.xml 7 def index 8 @gyms = Gym.find(:all) 9 respond\_to do |format| 10 format.html # index.html.erb 11 format.xml { render :xml =\> @gyms } 12 end 13 end And the test: def test\_should\_get\_index get :index assert\_response :success assert\_not\_nil assigns(:gyms) end This is a test that is being executed and does not fail. How come it’s not detected by rcov?? Thanks! / Vahagn
