Clearing the session of an integration test?

Hi -

I'm wondering if there is any way to clear the session after an integration test has been run. The situation I'm in is that I have 40+ unit tests that run fine on their own, but when I run them with the one integration test I have, the integration test causes a bunch of the unit tests to fail. I've tried reset! in teardown and setting @session=nil in the integration test, but that doesn't seem to make any difference. Has anyone else had this issue? TIA.
