Subject: [ruby-talk:24291] Newbie wrong # of arguments(4 for 0) question

Well I've finally found an excuse to write some ruby, and I haven't made it
far before
I've gotten myself stuck.  I remember a joke about the arguments error from
Ruby Conf,
but can't remember the punch line :(

I'm sure I am making some simple little mistake, but I have no pair so I am
at a loss.
If anyone can offer assistance I would be most appreciative.

Here is my test:
=========================
require 'revision'
require 'runit/testcase'
require 'runit/assert'
require 'runit/cui/testrunner'

class TestRevision < RUNIT::TestCase

  def setup
    super
  end

  def test_equals
    aRevision = Revision.new("1.4", "2001/10/21 02:30:18", "kbeck",
"Enhanced TextRunnerTest to catch missing return values.")
    bRevision = Revision.new("1.4", "2001/10/21 02:30:18", "kbeck",
"Enhanced TextRunnerTest to catch missing return values.")
    assert_equals(aRevision, bRevision)
  end
end

RUNIT::CUI::TestRunner.run(TestRevision.suite)
==========================

And the file I'm testing:

==========================
class Revision
  attr_reader :revision, :date, :name, :log
end
==========================

And of course, the error:

==========================
$ ruby test_revision.rb

TestRevision#test_equals E.
