 The '--test-name' option is mandatory.  The '--select' and '--exclude' options
 allow selecting or excluding individual test cases via a regexp, respectively.
 The '--errors-only' option can be set to \"yes\" to limit the logged test case
 metadata to only those test cases that failed.  When set to \"yes\", the
 '--brief' option disables printing the individual test case result to the
