Well this may not be the best way but it works.  Although it doesn't
record what methods were skipped.

    % cat platform-filter-test.rb 
    require 'test/unit'

    class MyTest < Test::Unit::TestCase

        def test_adams
           assert(42,"Life, Universe and Everything") 
        end

        def test_baz
            assert(true,"Baz is good")
        end

        def test_skip_mswin
            assert(RUBY_PLATFORM.match('mswin').nil?, "How could I fail.  I should have been skipped. I'm on Windows!!!")
        end

        def test_skip_darwin
            assert(RUBY_PLATFORM.match('darwin').nil?, "How could I fail.  I should have been skipped. I'm on MacOSX!!!")
        end
    end

    % ruby platform-filter-test.rb 
    Loaded suite platform-filter-test
    Started
    ..F.
    Finished in 0.00652 seconds.

      1) Failure:
    test_skip_darwin(MyTest) [platform-filter-test.rb:18]:
    How could I fail.  I should have been skipped. I'm on MacOSX!!!.
    <false> is not true.

    4 tests, 4 assertions, 1 failures, 0 errors


    % ruby platform-filter-test.rb --name='/test_(?!skip_darwin)/'
    Loaded suite platform-filter-test
    Started
    ...
    Finished in 0.000426 seconds.

    3 tests, 3 assertions, 0 failures, 0 errors

Its not very robust by any stretch of the imagination but if you want to skip
certain methods, regexp on the method names will work.  

enjoy,
