Undefined method `verify_active_connections!'

I’m getting this error for every test when I run rake

  1. Error:
    test_index(WatchlistsControllerTest):
    NoMethodError: undefined method verify_active_connections!' for ActiveRecord::Base:Class D:/svn_dbi/config/../vendor/rails/activerecord/lib/active_record/base.rb:996:inmethod_missing’
    c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.14.2/lib/active_record/fixtures.rb:536:in
    `teardown’

This started happening after the current version of rails was frozen
into the vendor folder, after which I upgraded both ruby and rails.

The app itself works fine by the way, its just the test suite that’s
broken.

Can anyone help us with this problem ? We’ve spent a good deal of time
on it with no success as yet.
