Trying to install new light fixture controlled with two light switches. I have two black and one white in the ceiling box. Should I connect all the black wires together?

How was the old fixture wired? – bib Feb 8 '14 at 18:03
I would expect that with two light switches controlling the light one black is from one switch and the other black is from the other switch. If so, then only one should be hot at a time. But, if I was uncertain, I would test with my multimeter and make sure the blacks are never hot at the same time. – getterdun Feb 9 '14 at 23:51
