Sugar doesn't melt. Rather, it decomposes. It decomposes into its constituent elements, which are C, H, and O. The H and O are given off as gases, leaving the C, carbon, left behind as a black mass in the bottom of the test tube. It's only carbon, presuming you heat it enough to drive off all of the sugar molecules.

The sugar is decomposed to carbon and water (as steam), You're left with the black carbon gunk in the test tube.

Small particles of suger will start moving inside the tube and then if the particles are big enough they can either break the tube or they may break themselves and start melting.
