# This file contains the test scripts for Thread:

# Case 1: Thread network formation and attaching
#         A Thread Border Router forms a Thread network, a Thread device attaches 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.
