    CircuitBreakersHealthIndicator healthIndicator = new CircuitBreakersHealthIndicator(registry, circuitBreakerProperties, new SimpleStatusAggregator());
    // then
    Health health = healthIndicator.health();
    then(health.getStatus()).isEqualTo(Status.DOWN);
    then(health.getDetails()).containsKeys(OPEN.name(), HALF_OPEN.name(), CLOSED.name());
