testCircuitLateSuccessDefaultSuccessThreshold

public void testCircuitLateSuccessDefaultSuccessThreshold()

Analagous to testCircuitDefaultSuccessThreshold but with a different success/failure pattern for the service that is called. In this case, the service succeeds in the last call in the rolling window but the circuit will still open as the failureRatio has been breached. With requestVolumeThreshold = 4, failureRatio=0.75 and successThreshold = 1 the expected behaviour is, Execution Behaviour ========= ========= 1 RunTimeException 2 RunTimeException 3 RunTimeException 4 SUCCESS 5 CircuitBreakerOpenException Pause for longer than CircuitBreaker delay, so that it transitions to half-open 6 SUCCEED (CircuitBreaker will be re-closed as successThreshold is 1. The impact of the success of the service and the closure of the Circuit is to reset the rolling failure window to an empty state. Therefore another 4 requests need to be made - of which at least 3 need to fail - for the Circuit to open again) 7 RuntimeException 8 RunTimeException 9 RunTimeException 10 SUCCESS 11 CircuitBreakerOpenException
