If this suggestion doesn't work, I am out of ideas.
Sometimes, when a breaker trips, it doesn't LOOK like it tripped. Did you try turning every breaker completely off then back on? If a breaker tripped without a visual appearance, that would reset it and put power back to the light fixture.
Personally, I don't like back feeding a circuit. But if you only do it for testing purposes, it should be harmless. I definitely don't like backfeeding one and leaving it live, but that is not what you are comtemplating.
Here is a Tone Generator. It does not require a circuit to be live, like the circuit tracer I mentioned earler. You hook the clips to the wires and activate the tone generator. The tracer then lets you follow/find the wires at least up until the break in the line. It may be safer than backfeeding the circuit. I have a tone tracer, but have never had a need to use it so I can't give any personal feedback on how useful it really is.
