Testunit, $DEBUG issue

Hi all,

Ruby 1.6.8
TestUnit 0.1.8

I’m having a bit of difficulty with testunit in conjunction with
$DEBUG. It just so happens that I want to run some tests with the
$DEBUG flag set to true. So, let’s say I have a class Foo:

foo.rb

class Foo
private_class_method :new
@@foo = nil
def Foo.create
@@foo = new unless @@foo
@@foo
end
end

And a test file:

tc_foo.rb

require “test/unit”
require “foo”
class TC_Foo < Test::Unit::TestCase
def setup
$DEBUG = true
end
def test_no_new
assert_raises(NameError){ f = Foo.new }
end
end

This runs ok, but I get some unwanted junk to STDERR:

ruby tc_foo.rb
Loaded suite tc_foo
Started
Exception NameError' at tc_foo.rb:8 - private method new’ called for
Foo:Class → I don’t want this
…
Finished in 0.005636 seconds.
1 tests, 1 assertions, 0 failures, 0 errors

Trying to do something like STDERR.close won’t help, because then you
can end up with something like:

IOError: closed stream
foo.rb:15:in close' foo.rb:15:in setup’
foo.rb:2

Is there a proper way to prevent the output to STDERR in testunit? Keep
in mind that I would like a solution that works on MS Windows, as well
as *nix (so, no redirecting to /dev/null).

Regards,

Dan
