### Question:
RqueueConfig { public String getProcessingQueueChannelName(String queueName) { if (dbVersion == 1) { return "rqueue-processing-channel::" + queueName; } return prefix + getProcessingQueueChannelSuffix() + getTaggedName(queueName); }  String getQueuesKey(); String getQueueName(String queueName); String getDelayedQueueName(String queueName); String getDelayedQueueChannelName(String queueName); String getProcessingQueueName(String queueName); String getProcessingQueueChannelName(String queueName); String getLockKey(String key); String getQueueStatisticsKey(String name); String getQueueConfigKey(String name);  }### Answer:
@Test public void getProcessingQueueChannelName() { assertEquals( "rqueue-processing-channel::test", rqueueConfigVersion1.getProcessingQueueChannelName("test")); assertEquals( "__rq::p-channel::test", rqueueConfigVersion2.getProcessingQueueChannelName("test")); assertEquals( "__rq::p-channel::{test}", rqueueConfigVersion2ClusterMode.getProcessingQueueChannelName("test")); }
