Many tests skip tests for various reasons but not in a consistent way and don't always clean up, so add that and switch the tests that do that over. OpenBSD-Regress-ID: 72d2ec90a3ee8849486956a808811734281af735

# Placed in the Public Domain.

|
# This test requires external setup and thus is skipped unless
|
|
# TEST_SSH_SSHFP_DOMAIN is set. It requires:
|
|
# 1) A DNSSEC-enabled domain, which TEST_SSH_SSHFP_DOMAIN points to.
|
|
# 2) A DNSSEC-validating resolver such as unwind(8).
|
|
# 3) The following SSHFP records with fingerprints from rsa_openssh.pub
|
|
# in that domain that are expected to succeed:
|
|
# sshtest: valid sha1 and sha256 fingerprints.
|
|
# sshtest-sha{1,256}, : valid fingerprints for that type only.
|
|
# and the following records that are expected to fail:
|
|
# sshtest-bad: invalid sha1 fingerprint and good sha256 fingerprint
|
|
# sshtest-sha{1,256}-bad: invalid fingerprints for that type only.
