You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: redirect_to_matcher.rb
    path of file: ./repos/shoulda-matchers/lib/shoulda/matchers/action_controller
    
    the code of the file until where you have to start completion: module Shoulda
  module Matchers
    module ActionController
      # The `redirect_to` matcher tests that an action redirects to a certain
      # location. In a test
    
        def redirects_to_url?
          @context.__send__(:assert_redirected_to, url)
          @failure_message_when_negated = "Didn't expect to redirect to #{url}"
          true
        rescue Shoulda::Matchers.assertion_exception_class => e
          @failure_message = e.message
          false
        end
