Does this apply to all tests - unit, functional, etc? I got my unit
tests working, but my functionals are not.

Sure. Navigating to a sections#show page yields a screen that says
"NoMethodError in SectionsController#show
undefined method `paginate' for #<Class:0x5eb4ad0>"
so I immediately realize I need to check wherever I call paginate and
see if the method is implemented.

Running the functional test
ruby -I test test/functional/sections_controller_test.rb
Only yields this:
1) Error:
test: A section should respond with 200. (SectionsControllerTest):
NoMethodError: undefined method `response_code' for nil:NilClass

This doesn't mean anything to me. (In my test, I had should
respond_with :success.)
