Usage:
    tap <options> <files>

    Run the files as tap tests, parse the output, and report the results

Options:

    --stderr    Print standard error output of tests to standard error.
    --tap       Print raw tap output.
    --diag      Print diagnostic output for passed tests, as well as failed.
                (Implies --tap)
    --timeout   Maximum time to wait for a subtest, in seconds. Default: 30
    --version   Print the version of node tap
    --help      Print this help
