The general guideline is to use __init__() for your class instance
needs, and use setUp() for getting your test ready to run.

Given that the __init__() interface is used by the test runner, and
having the minimal amount of code there will minimize problems with
runner<->test communication, I'd leave it alone as much as possible and
use setUp() instead.
