### Question:
CircuitBreaker { public void setStateForBypass(State state) { this.state = state; } CircuitBreaker(long timeout, int failureThreshold, long retryTimePeriod); String getState(); void setStateForBypass(State state); String call(String serviceToCall, long serverStartTime);  }### Answer:
@Test public void testSetStateForBypass() { var circuitBreaker = new CircuitBreaker(1, 1, 100); circuitBreaker.setStateForBypass(State.OPEN); assertEquals(circuitBreaker.getState(), "OPEN"); }
