36 * Main class of Yang parser system test.
39 * yang-system-test [-f features] [-h help] [-p path] [-v verbose] yangFiles...
40 * -f,--features <arg> features is a string in the form
41 * [feature(,feature)*] and feature is a string in the form
42 * [($namespace?revision=$revision)$local_name].
43 * This option is used to prune the data model by removing
44 * all nodes that are defined with a "if-feature".
45 * -h,--help print help message and exit.
46 * -p,--path <arg> path is a colon (:) separated list of directories
47 * to search for yang modules.
48 * -r, --recursive recursive search of directories specified by -p option
49 * -v, --verbose shows details about the results of test running.
50 * -o, --output path to output file for logs. Output file will be overwritten.
51 * -m, --module-name validate yang by module name.
52 * -wul, --warning-for-unkeyed-lists
53 * add warnings about unkeyed lists with config true.
