Subject: Rubicon -> Test::Unit

Are there plans a foot for Rubicon to use Test::Unit?

I ask because we currently use Rubicon's BulkTestRunner
to summarize our RubyUnit test results via

 <file name="IntegrationTest.rb">
  #!/usr/bin/env ruby
  $:.push(File.join($:[0],"rubicon"))
  require 'rubicon'

  tests = Rubicon::BulkTestRunner.new([],"Built-ins")
  Dir["*UT.rb"].each {|ut| tests.addFile(ut)}
  tests.run
 </file>

after placing Rubicon in lib/ruby/site_ruby/1.6/ and
hacking it's relative path loop, viz,

 105,106c105,106
 < for relative_path in [ ".", ".." ]
 <   util = File.join(run_dir, relative_path, "util")
 ---
 > for relative_path in [ run_dir, File.join(run_dir, ".."), *$: ]
 >   util = File.join(relative_path, "util")

So IntegrationTest.rb produces something like the following when
run in our directory full of source/tests:

 [..]

 BoundaryProfileUT: ......
 Time: 0.012816
 OK (6/6 tests  28 asserts)

Note: each TestSuite still has to use the old-syle RubyUnit
format, otherwise all the tests are executed twice, e.g.,

 <file name="LineFitUT.rb">
  require 'runit/testcase'
  require 'LineFit'

  class LineFitUT < RUNIT::TestCase
   def testSlope
    array = [[0,0], [0.5,0.5], [1,1]]
    assert_equal(1, LineFit.leastSquaresSlope(array))
    array = [[0,0], [0.5,0.5], [1,0]]
    assert_equal(0, LineFit.leastSquaresSlope(array))
   end
  end

  if $0 == __FILE__ then
   require 'runit/cui/testrunner'
   RUNIT::CUI::TestRunner.run(LineFitUT.suite)
  end
 </file>
