# This file contains the test scripts for Thread:

# Case 1: Thread network formation and attaching
#         A Thread Border Router forms a Thread network, Thread devices attache to it, then test ping connection between them.

# Case 2: Bidirectional IPv6 connectivity
#         Test IPv6 ping connection between Thread device and Linux Host (via Thread Border Router).

# Case 3: Multicast forwarding from Wi-Fi to Thread network
#         Thread device joins the multicast group, then test group communication from Wi-Fi to Thread network.

# Case 4: Multicast forwarding from Thread to Wi-Fi network
#         Linux Host joins the multicast group, test group communication from Thread to Wi-Fi network.

# Case 5: discover Serice published by Thread device
#         Thread device publishes the service, Linux Host discovers the service on Wi-Fi network.

# Case 6: discover Serice published by W-Fi device
#         Linux Host device publishes the service on Wi-Fi network, Thread device discovers the service.

# Case 7: ICMP communication via NAT64
#         Thread device (IPV6) ping the host device (IPV4) via NAT64.

# Case 8: UDP communication via NAT64
#         Thread device (IPV6) send udp message to the host device (IPV4) via NAT64.

# Case 9: TCP communication via NAT64
#         Thread device (IPV6) send tcp message to the host device (IPV4) via NAT64.
