method undefined in integration test

Hello list,

I’m having problems with the following integration test (tests for the authentication aspects of the application):

require “#{File.dirname(FILE)}/…/test_helper”

class AuthenticationTest < ActionController::IntegrationTest

fixtures :your, :models

def test_successful_login george = enter_site(:george)

end

module BrowsingTestDSL include ERB::Util attr_writer :name

def tries_to_go_to_admin
  get "/admin/book/new"
  assert_response :redirect
  assert_redirected_to "/account/login"
end

def enter_site(name)
  open_session do |session|
    session.extend(BrowsingTestDSL)
    [session.name](http://session.name) = name
    yield session if block_given?
  end

end

end

end

When I run this test, rails tell me test_site() is undefined, however, I’ve declared it inside the private module (I’m using the module to implement this test’s DSL, as seen in the book Beginning Ruby on Rails E-Commerce from Apress).

Here’s the output:

"Loaded suite test/integration/authentication_test Started E Finished in 0.312 seconds.

  1. Error: test_successful_login(AuthenticationTest): NoMethodError: undefined method `enter_site’ for #ActionController::Integration::Session:0x4751620

What am I doing wrong ?

Thanks in advance,

Your module isn't included (in the sense of "include ModuleName") in your class. So instances of your class do not have the module in their method lookup path.

Here's a very small version, with the include instruction added:

   class C      def x        y      end

     module M        def y          puts "hi"        end      end

     include M # This is the key line    end

The fact that the module is nested in the class doesn't matter; it's still just a module (C::M in my case), and it has to be included in any class that wants its objects to have access to it.
