The test is about SCTP and the accessed service only forwarded SCTP
traffic to the server Pod but the client Pod used TCP protocol, so the
test traffic never reached the server Pod and the test NetworkPolicy
was never enforced, which lead to test success even if the default-deny
policy was implemented wrongly. In some cases it may got failure result
if there was an external server having same IP as the cluster IP and
listening to TCP 80 port.
