After Rails 2.3.2 upgrade: superclass mismatch for class TestCase (TypeError)

I upgraded a working app from rails 2.1 to 2.3.2. Now when I run rake
test:units I get this error: /usr/lib/ruby/gems/1.8/gems/
activesupport-2.3.2/lib/active_support/test_case.rb:17: superclass
mismatch for class TestCase (TypeError)

I generated a new test app and all tests run OK.

For the upgrade I ran rake:update and renamed the class in test_helper
to ActiveSupport::TestCase. Also renamed the classes in all unit tests
and to inherit from ActiveSupport::TestCase and in functional tests to
inherit from ActionController::TestCase.
I still could not fix it this error. I compared line by line the
config files and the test_helper.rb with a brand new app and there are
almost the same. Google didn''t provide any clue.

Full stack trace here:

Looks to me like you accidentally declared a new class called
ActiveSupport::TestCase. You said your test_helper.rb is almost the
same as one in a freshly generated app - what are the differences?

This is the diff between the two test_helper.rb (one being the virgin
one, the second being the new one). Not much of a difference but my
extra functions.

There must have been a plugin that changed the class TestCase class. I
realized that have done a search and replace in the plugins folder too
for Test::Unit::TestCase and replaced it to ActiveSupport::TestCase. I
did an svn revert on plugins and the rake test:units don''t show the
superclass mismatch for class TestCase error.
