Thanks for the answer, but things still don't seem to work the way I would
expect, the following fails (at least for me):
-------------------------------------------------
require 'runit/testcase'
require 'runit/testsuite'

class RaiseException
  def initialize(aString)
    raise aString
  end
end

class TestExcept < RUNIT::TestCase
    def testExcept
      err = assert_exception("RunTimeError","test failed") do
	RaiseExeption.new("this is an exception")
      end
      assert_equals("this is an exception",err.to_s)
    end
end

if $0 == __FILE__
    require 'runit/cui/testrunner'
    RUNIT::CUI::TestRunner.run(TestExcept.suite)
end
-------------------------------------------------

The failure message is:
-------------------------------------------------
[pate@cherry ruby]$ ./testExcept.rb

TestExcept#testExcept E.
Time: 0.002723
FAILURES!!!
Test Results:
 Run: 1/1(1 asserts) Failures: 0 Errors: 1

./testExcept.rb:15:in `testExcept': class or module required (TypeError)
        from ./testExcept.rb:23
[pate@cherry ruby]$
-------------------------------------------------

Obviously, I'm not understanding things here.  Any ideas?  Other than that
I'm an idiot. ;)

thanks,
-pate
