Want to know the behavoir of your app if a Hystrix Circuit is open?

Run with the circuit open

Run your spring cloud app with -Dhystrix.command.<circuitKeyName>.circuitBreaker.forceOpen=true

<circuiktKeyName> is the name of you hystrix circuit. If you used @HystrixCommand it is the name of the method. If you used @HystrixCommand(commandKey="mykey") is is the value of the commandKey attribute.
