How do I troubleshoot a fluorescent fixture that doesn't light?

How do I check the starter in the fluorescent fixture?

Older, delayed-start fluorescent lights flicker when they first light up. If this lasts more than a couple of seconds, make sure the starter is seated by pushing it in and turning clockwise.
