“undefined method `use_transactional_fixtures=’” after upgrading to Rails 2.3.2

After upgrading to Rails 2.3.2 I’ve tried to run the testcases. The following error occured: test/test_helper.rb:22: undefined method `use_transactional_fixtures=’ for Test::Unit::TestCase:Class (NoMethodError) Solution: Test::Unit::TestCase changed to ActiveSupport::TestCase, so simply edit your test/test_helper and change the name of the class. Keywords: functional test problems
