There is verifier testsuite that is testing eBPF verifier from userspace
via bpf syscall. Also there are multiple examples and libbpf.
I think test coverage for bpf syscall is quite substantial already.

As far as manpage I already mentioned my plan in the other thread.
I will do it when stuff lands, since writing docs in english is the most
difficult part of these patches. I already rewrote Documentation/../filter.txt
several times. Even once Kees noticed discrepancies there when
interface changed from map_id to map_fd.
To do a manpage I'll use a help from tech writer, since I want it to
be better than docs I put in Documentation/...
