What Peter said, one wheel on bitumen and one on grass or gravel. You should be able to move off with one wheel spinning about 5X faster than the other, where an open diff will sit there spinning one wheel. To test for TRC, put both rear wheels on the grass. Signs of TRC will be obvious, with the engine cutting power and lights coming up in the dash.
Those are the practical tests. Blake gave the things to look for to find out whether you should have TRC. For the diff, check the build plate in the engine bay. If it says "Trans/Axle A01A" then it will have a Torsen diff only if a previous owner put one into it, not from the factory.
