Chad Fowler and I are working on upgrading rubicon for ruby-1.8.1.
We have made a transition from rubyunit to now use testunit.

I am working with the CVS version (I don't think there is a newer rubicon
suite?)  ;-)

You can see the pending bugs here:
http://rubyforge.org/tracker/?func=browse&group_id=179&atid=751
Please comment on these :-)


The code which I am looking at is

  def test_LSHIFT # '<<'
    File.open(@file, "w") do |file|
      io = IO.new(file.fileno, "w")
      io << 1 << "\n" << Dummy.new << "\n" << "cat\n"
      io.close
    end
    expected = [ "1\n", "dummy\n", "cat\n"]
    IO.foreach(@file) do |line|
      assert_equal(expected.shift, line)
    end
    assert_equal([], expected)
  end 

Why make an instance of the IO class, when its the '<<' leftshift
operator we want to test?
