Unfortunately, there is no command line option to do what you want.  If 
you want to see the available command line options, run a test with the 
'--help' option.  You'll see something like this:

Test::Unit automatic runner.
Usage: test/unit/graph_test.rb [options] [-- untouched arguments]

    -r, --runner=RUNNER              Use the given RUNNER.
                                     (c[onsole], f[ox], g[tk], g[tk]2, 
t[k])
    -n, --name=NAME                  Runs tests matching NAME.
                                     (patterns may be used).
    -t, --testcase=TESTCASE          Runs tests in TestCases matching 
TESTCASE.
                                     (patterns may be used).
    -v, --verbose=[LEVEL]            Set the output level (default is 
verbose).
                                     (s[ilent], p[rogress], n[ormal], 
v[erbose])        --                           Stop processing options 
so that the
                                     remaining options will be passed to 
the
                                     test.
    -h, --help                       Display this help.

Deprecated options:
        --console                    Console runner (use --runner).
        --gtk                        GTK runner (use --runner).
        --fox                        Fox runner (use --runner).

I've written a blog post about the options (the -n one is *really* 
useful) at
