With the power of, disconnect the wires to the compressor and check for continuity across the windings. It should look something like this:

If there is an open circuit then the compressor is toast. If not then check wires back to the switch for continuity. You can do a rough check of the capacitor using an ohm meter. Discharge the cap by shorting the terminals with a screwdriver then check for resistance across the terminals. Resistance should start at zero ohms and then increase to infinity as the capacitor gets charged by the meter.
