lksctp-tools git repo is a good start.  There 2 different sets of test:

1.  Frame tests in lksctp-tools/test.  These run the kernel sctp code in
userspace and are programmable to do whatever you want.  You can add tests
to cover new functionality or ever force corner cases.  The only limitation
of these is that you can't simulate race conditions.

2.  Userspace functional tests in lksctp-tools/src/func_tests.  These are mostly
API tests.

That's a good start.  You can add to it anything that could be missing.

One warning about frame tests.  You need different version of them for each
different kernel version.  They depend on the kernel internals and when those change
we have to continually change these tests.
