Just spent a good bit of time trying to figure out why I couldn't get

ActiveSupport::TestCase *does* have fixtures support, I'm not sure
what you're trying to get done here?
Yes it does. But it was silently failing.
The problem was in the first line of
ActiveRecord::TestFixtures.setup_fixtures:
return unless defined?(ActiveRecord)&&
!ActiveRecord::Base.configurations.blank?
This causes setup_fixtures to silently return without doing anything if you
call ActiveRecord::Base.establish_connection directly without setting
ActiveRecord::Base.configurations. The method doesn't appear to actually use
the configurations.
Is there some reason for this behavior? It appears like it should be removed
to me, but if it is there for a reason, maybe it can be documented that
populating configurations is a prerequisite to using fixtures in plugins.
This is to avoid breaking people trying to use ActiveSupport::TestCase
subclasses without active record configured in their application, we
could change that logic to support your case where you've connected
manually, but due to how things are laid out there'll still need to be
some short-circuiting behaviour to avoid a bunch of misleading errors.
In a plugin we have to explicitly include ActiveRecord::TestFixtures to
enable fixtures in ActiveSupport::TestCase. So my thinking is it should
loudly fail instead of silently fail if it doesn't think ActiveRecord is
setup. Now if I understand you correctly, you are saying that that would
cause problems in Rails applications that aren't using ActiveRecord,
because the main Rails test framework automatically includes
ActiveRecord::TestFixtures into ActiveSupport::TestCase. It's probably
not be worth changing Rails to only include ActiveRecord::TestFixtures
into ActiveSupport::TestCase if ActiveRecord is in use, but it would be
helpful to document somewhere the dependency between
ActiveRecord::Base.configurations and fixtures.

I am using 2.3.5 but it appears to still be the case in edge.
