Missing test helpers

I seem to be missing a test helper I thought was
standard...`assert_session_has', any ideas?

A google search led me to
http://rubythis.blogspot.com/2006/12/ruby-on-rails-deprecations-part-1.html
which suggests assert_session_has was deprecated in 2006 so I imagine
it is long gone now. The suggestion there is to use
assert(@response.has_session_object?(key)) but I cannot vouch for
that.

Guess I'm behind the times...thanks!
