A timing light is a good way of checking. No flash = no spark. Another trick you can play with breaker point ignitions is to power up the ignition and twist the distributor back and forth to open and close the points. It will spark each time the points open. In fact, this is a good way to set base timing. Align the marks and turn the distributor until it sparks.
