You can run an individual test from the top-level Makefile, eg:

@ -82,16 +93,12 @@ Failed tests can be difficult to diagnose. Suggestions:
Known Issues.
- If you build with tcpwrappers and try to run the regression tests,
your hosts.allow must permit connections from localhost and from
"unknown". This is because some tests are performed via the loopback
interface, while others are done with "sshd -i" as a ProxyCommand. In
the latter case, when sshd calls getpeername() on the socket it will
fail (because it's not a tcp socket) and will be identified as
"unknown", which is then checked against tcpwrappers.
- If your build requires ssh-rand-helper regress tests will fail
unless ssh-rand-helper is in pre-installed (the path to
ssh-rand-helper is hard coded).
$Id: README.regress,v 1.4 2004/03/08 20:12:18 tim Exp $
- Recent GNU coreutils deprecate "head -[n]": this will cause the yes-head
test to fail. The old behaviour can be restored by setting (and
exporting) _POSIX2_VERSION=199209 before running the tests.
