Rails - Jul 2005 - testing application_helper.rb

I am trying to run some functional (or are they unit?) tests on my
application_helper.rb.  So far, I''ve not had any success in being able
to call the methods defined in application_helper.rb.

Here is my app/test/functional/helpers.rb

require File.dirname(__FILE__) + ''/../test_helper''
require File.dirname(__FILE__) +
''/../../app/helpers/application_helper''

class HelpersTest < Test::Unit::TestCase
  def setup
  end

  def test_foo
    result = foo( "test parameter 1" )
    assert_equal true, result
  end

end

However, I get method not found errors (it can''t find foo()) when
trying to run the test.  What am I doing wrong?

Similarly, how does one go about functional testing application.rb?

Thanks.

Matt

     # You may need to pull in some other helpers, depending on what
     # your helpers depend on, like this:
     # include ActionView::Helpers::TextHelper

     # Pull in your helper(s)
     include ApplicationHelper

Matt, define a new class which includes the helber module and use  
this class within your test:

require File.dirname(__FILE__) + ''/../test_helper''

class ApplicationHelperTest < Test::Unit::TestCase

   class MyApplicationHelper
     include ApplicationHelper
   end

   def setup
     @ah = MyApplicationHelper.new
   end

   def test_truth
     assert_equal 4, @ah.foo
   end
end

I figured it out.  I feel silly now.  I had simply left out the
include statements:


require File.dirname(__FILE__) + ''/../test_helper''
require File.dirname(__FILE__) +
''/../../app/helpers/application_helper''
require "erb"
include ERB::Util
include ApplicationHelper
