Rails - Aug 2007 - 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 = 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

`run

What am I doing wrong ?

Thanks in advance,

Marcelo.

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.
