Dear Yao, First of all, are you on MASTER branch or some other release? Second, can you run "make test TEST=test_sctp.py" and see if that works for you? It all looks good on my side and on Jenkins. If you are interested in running multiple clients, you can do that by editing test_sctp.py and add "nclients X" (where X can be 2 or more). Again, I have just tested it right now and I cannot see that issue.
