Usually with Thermostats and easy way to test if they still work, grab a lighter or match and hold the flame to the top of the thermostat. MAKE SURE THE FLAME IS NO CLOSER THAN AN INCH (or so). You should hear a pop, if it doesn't time to replace the thermostat. Also another easy way if to use a continuity tester, to see if there's a current.

For the thermostat only it is easier than the other directions if you don't mind working with it energized, hot. Read voltage across the two wire connections. If it is open it will read 220 if closed then zero. Then you can turn the temp setting up or down and see if it clicks. Then check again. If you know the temp of the water in the tank you can get an idea of what range it is tripping. If there is a huge range between open and closed it can be a bad Tstat as well. If the tank is totally cold it may not trip off though. You didn't say what it was doing.

Are you doing this just for grinns and giggles? I assume you have a problem. You could get a lot more help if you explained what was wrong with the water heater. If you'r sure it's a thermostat problem just replace both of them. It would be cheaper than a volt ohm meter and learning how to use it properly. Oh, be sure the power is off. Of corse a volt meter is the only way to be sure. Oh well, so much for saving money.

The thermostat is in the two screws at the head, be careful these are active electrical wires and you can get a good shock off them.
Use a regular Ohm meter to just jump the connections, if they're working you'll get a reading, they should read 120.
If you think one is out you won't get a reading. Simple
