What kind of circuit tester do I need?

Well, if you're sure the bulb is good, and it's not coming on, that means the power is not getting to the bulb. So your fixture is broken, or the power is not getting to the fixture.

I guess my do-it-yourself homeowner approach would be to remove the screws to the fixture, and pull it down to see if one of the wires has come loose. If not, the problem is further on. That's my "tester".

I dunno- I've been briefly shocked by 110 enough times without injury that I may be overly casual about such things. If you do accidentally short circuit the thing, there will be a bright crack!, but that'll pop the breaker, and then you'll know what circuit it is.

In retrospect, I may not be the best person for advice in this regard though. (!)

I am 99% sure that the little pull chain thing that turns it on is where it is broken. I had this happen once before, the switch just goes bad, so that pulling the chain doesn't complete the circuit. This fixture gets turned on/off a lot, so it is no wonder they just wear out, after a while.
