Capp::TestCase contains some useful methods for testing parts of Capp.
The _DUMP constants are created from pcap files in the test directory. You can create your own capture from tcpdump:
tcpdump -r test/my.pcap [your specific capture arguments]
An ARP packet
An EAP 802.1X packet
An ICMPv4 packet
An ICMPv6 packet
A TCPv4 packet
A TCPv6 packet
A UDPv4 packet
A UDPv6 packet
Returns the first packet in dump
