Overview

This cop makes sure that Rails helpers only uses class methods in order to be able to use them in the test, views or from anywhere else. ApplicationHelper is excluded from this rule by default.

Examples:

# bad
module CoolHelper
  def foobar
    # ...
  end
end

# good
module CoolHelper
  def self.foobar
    # ...
  end
end
