+# 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.
