Subject: Test::Unit Patch that allows test methods to be executed sequentially

This patch to Test::Unit allows you to create TestCases whose test
methods will be executed in the order you've defined them, rather than
alphabetically, which is what Test::Unit does today.

http://wiki.openqa.org/display/WTR/Test-Unit+Patch

Thus the foloowing TestCase will print "EFGH":

class TC2_Sequential < Test::Unit::TestCase
  execute :sequentially
  def test_b; print 'E'; end
  def test_a; print 'F'; end
  def test_d; print 'G'; end
  def test_c; print 'H'; end
end

I realize that there has been some controversy in the past about
whether is a good idea or not. This debate has hinged on issues about
proper unit testing.

However, with Watir (http://wtr.rubyforge.org), many people are now
using Test::Unit for system acceptance testing, which presents a
different context for the value of ordering tests.

My hope is that some people will find this to be useful. My thanks go
to Why's MetaClass article, which gave me the info i needed to create
this.
