Subject: run only one test case?

Rubies:

Here's a normal example of running a Ruby/Unit suite:

    aTestSuite = Test::Unit::TestSuite.new("MRW")
    aTestSuite << a bunch of suites
    got = runner.run(aTestSuite)

The above code runs all test cases. I want to run only one of them.

A "test suite" is (generally) a list of test cases. Here, it is a list of 
lists of test cases. Running only one *.rb file would run all cases in that 
file's suites. I want to run only one test case. Here are three test cases:

class SomeSuite < Test::Unit::TestCase

    def test_runThisCase()
       #...
    end


    def test_dontRunThis()
       #...
    end

    def test_orThis()
       #...
    end

end

Running SomeSuite is trivial.

Now how to augment that so if a caller has supplied one case name (perhaps 
via command line arguments and ARGV[]), and then only run that one case?

Suppose I only want to run test_runThisCase. If I had invented Ruby/Unit, we 
could run it like this:

  got = runner.run(aTestSuite, 'test_readMyPost')

Unfortunately, the test.rb files (like many Ruby library files) are 
write-only, and I generally can't read them well enough to understand how to 
apply that syntax. Is such a feature available through these objects?

Alternately, could I loop thru aTestSuite's cases, find it, and run it?

(I'm not asking how to run test suites, or how to parse command line
arguments here!)
