Rails - Jul 2006 - NoMethodError in Unit Test - Rails Newcomer

I''m working on user authentication system to get familiar with rails, 
and have basically solved most of my apps problems till now.  I keep 
getting the NoMethodError, and can''t understand why.

Model: customer.rb
class Customer < ActiveRecord::Base

...
def self.password=(pass)
	    @password=pass
	    salt = Customer.random_string(10) if !salt?
	    self.hashed_password = Customer.encrypt_password(@password, salt)
	end
end

Test: customer_test.rb
require File.dirname(__FILE__) + ''/../test_helper''

class CustomerTest < Test::Unit::TestCase
  self.use_instantiated_fixtures = true
  fixtures :customers

...

#  change password
	@longbob.password = @longbob.password_confirmation =
"newlongpassword"
	assert @longbob.save

        c = Customer.new
	c.email_address = "jimbo@mcjim.com"
#  ok
	c.password = c.password_confirmation = "magicwand"
	assert c.save



The error I keep getting is this (it happens in all of my tests):

4) Error:
test_passwordchange(CustomerTest):
NoMethodError: undefined method `password='' for
#<Customer:0x343de40>
    C:/Program 
Files/Ruby/lib/ruby/gems/1.8/gems/activerecord-1.14.3/lib/active_record/base.rb:1789:in
`method_missing''
    test/unit/customer_test.rb:28:in `test_passwordchange''


I''m not sure what I''m doing wrong, but I''m 100% sure
that the password
method exists for that model.  Any ideas?

It should be just def password= ...

Omitting the ''self,'' I get this more-verbose error for some of
the
tests:

1) Error:
