They are not coupled with the web tier. They only require _something else_ to close the session at the appropriate time. In a web application, it happens to be a servlet filter. In test cases, it happens to be the tearDown() method. There is no dependency on the web tier when running the test cases. If you have other scenarios, you just need to find an appropriate place to close the session (maybe a controller of some sort).
