I posted this on comp.lang.ruby and thought it would be in my best interest to post it here too. I''ve written a custom validation method (to validate an email address). It looks like module ActiveRecord module Validations module ClassMethods def validates_as_email ... end end end end I''ve put this code in app/lib/custom_validations.rb Now, I''m trying to write a unit test but I''m running into problems. One attempt at a unit test looks like require File.dirname(__FILE__) + ''/../test_helper'' require ''lib/custom_validations'' class CustomValidationsTest < Test::Unit::TestCase def test_validates_as_email email = "some...-hcDgGtZH8xNBDgjK7y7TUQ@public.gmane.org" assert validates_as_email( email ) end end This throws a NoMethodError: undefined method `validates_as_email'' for #<CustomValidationsTest:0x314bd80> It looks to me like the test is looking for the validates_as_email method to be defined in CustomValidationsTest rather than finding it in lib/custom_validations.rb So, I tried this require File.dirname(__FILE__) + ''/../test_helper'' require ''lib/custom_validations'' class CustomValidationsTest < Test::Unit::TestCase def test_validates_as_email email = "some...-hcDgGtZH8xNBDgjK7y7TUQ@public.gmane.org" assert ActiveRecord::Validations::ClassMethods.validates_as_email( email ) end end And I got this error NoMethodError: undefined method `validates_as_email'' for ActiveRecord::Validations::ClassMethods:Module What am I missing? I''ll bet it''s something simple, but I just can''t figure out what''s wrong.
