Add_assertion' called for nil:NilClass errror when testing

This @browser is defined in the login method
@browser=Selenium::Client::Driver.new("localhost", 4444, "*chrome", $url
, 10000);

class CrudDContent<Test::Unit::TestCase
   def initialize()
    login("browser_name")
   end#initialize()

   def test_createdc()
     assert(@browser.element?($x_xpath))#the test fails at this assert
   end#test_createdc()

end#CrudDContent<Test::Unit::TestCase

When ever I run this program, I get the error :

C:/RubyInstall/ruby/lib/ruby/1.8/test/unit/testcase.rb:125:in
`add_assertion': private method `add_assertion' called for nil:NilClass
(NoMethodError)
  from C:/RubyInstall/ruby/lib/ruby/1.8/test/unit/assertions.rb:494:in
`_wrap_assertion'
  from C:/RubyInstall/ruby/lib/ruby/1.8/test/unit/assertions.rb:61:in
`assert'
  from ./content.rb:6:in `test_createdc'
  from Driver.rb:8

Can someone take a look, I am out of ideas!

Fixed, I needed to add the initalize the test methods after I called
them

  dc=CrudDContent.new()

  def initialize(dc)
    super(dc)
    end #def initialize(dc)

  dc.test_createdc()
