Helper Specs live in $RAILS_ROOT/spec/helpers/.
Helper Specs use Spec::Rails::Example::HelperExampleGroup, which allows you to include your Helper directly in the context and write specs directly against its methods.
HelperExampleGroup also includes the standard lot of ActionView::Helpers in case your helpers rely on any of those.
class ThingHelper
def number_of_things
Thing.count
end
end
describe "ThingHelper example_group" do
include ThingHelper
it "should tell you the number of things" do
Thing.should_receive(:count).and_return(37)
number_of_things.should == 37
end
end
Returns an instance of ActionView::Base with the helper being spec‘d included.
describe PersonHelper do
it "should write a link to person with the name" do
assigns[:person] = mock_model(Person, :full_name => "Full Name", :id => 37, :new_record? => false)
helper.link_to_person.should == %{<a href="/people/37">Full Name</a>}
end
end
module PersonHelper
def link_to_person
link_to person.full_name, url_for(person)
end

TODO: BT - Helper Examples should proxy method_missing to a Rails View instance. When that is done, remove this method
