/**
 * Unit tests for PushServerUpdateJob status aggregation logic.
 *
 * These tests verify that the job correctly aggregates container statuses
 * when processing Sentinel updates, with proper handling of:
 * - running (healthy) - all containers running and healthy
 * - running (unhealthy) - some containers unhealthy
 * - running (unknown) - some containers with unknown health status
 *
 * The aggregation follows a priority system: unhealthy > unknown > healthy
 *
 * This ensures consistency with GetContainersStatus::aggregateApplicationStatus()
 * and prevents the bug where "unknown" status was incorrectly converted to "healthy".
