Detailed Description

Queue Disc Traces Test Case.

This test case makes use of a test queue disc acting as root queue disc and having a single child queue disc, which has a single DropTail queue. The Enqueue, Dequeue, DropBeforeEnqueue and DropAfterDequeue traces of both queue discs are connected to the methods of TestCounter objects that keep track of the amount of packets/bytes queued inside each queue disc and the cumulative amount of packets/bytes dropped before enqueue and after dequeue. A series of enqueue, dequeue and peek operations are performed on the root queue disc and both the statistics kept by the QueueDisc class and the values computed by the TestCounter objects are compared with the expected values.
