The "#<#<Class:0xb63d37ac>" error shows up when using
helper.check_param in the order_link method as you suggested. The
"#<RSpec::Core::ExampleGroup::Nested_1" shows up with just using
check_param (without "helper.").

> This ^^ message tells us that sort_direction is not implemented on the example. The new message (above) tells us that fetch_param is not implemented on the helper object, which means one of two things:
> 1) fetch_param is not implemented as an instance method in the ApplicationHelper module. This would be just a matter of implementing it.

It should be. It works when viewing that template in the browser.

> 2) ApplicationHelper is not included in the helper object. It should be included if the spec file is in spec/helpers. Is it?

order_link is known and that is a method of ApplicationHelper, so I
guess it is included.
