Firstly check out the rating of capacitor you want to check.According to voltage rating given on capacitor, apply the voltage to its two terminals(Note :Do not apply the voltage more than rating voltage,otherwise it will make a short circuit,less voltage can be applied) and then short those terminals.if spark between terminals is observed it is good otherwise it is bad.
