Tests use cleanUp rather than tearDown

The tests were putting clean-up code in tearDown. Using tearDown
causes problems with developing and testing because if there's an
exception raised in setUp then tearDown is not called and this
can affect other tests and make it hard to figure out what the
problem was.

Also, this should make it easier to switch to using fixtures since
fixtures use cleanUp.
