6 # Helper Specs use Spec::Rails::Example::HelperExampleGroup, which allows you to
7 # include your Helper directly in the context and write specs directly
8 # against its methods.
9 #
10 # HelperExampleGroup also includes the standard lot of ActionView::Helpers in case your
11 # helpers rely on any of those.

22 # include ThingHelper

24 # Thing.should_receive(:count).and_return(37)
25 # number_of_things.should == 37
