+# File of DHCP-DDNS configuration permutation tests
+# Each test entry consists of:
+#
+# description - text describing the test (optional)
+# syntax-error - syntax error the JSON parsing should emit for this test
+#               defaults to "" = no error
+# logic-error - indicates whether a post-JSON parsing logic error should occur
+#               defaults to false
+# data {} - Configuration text to submit for parsing.
+#
+# The vast majority of the tests in this file are invalid and are expected
+# to fail either as a syntax error caught by the JSON parser or a logic error
+# caught during element processing. There are some that should succeed and are
+# used more or less as sanity checks.
