Trouble with FileUtils.rm_rf / .rmdir

I am trying to dynamically setup and teardown a directory structure for
testing. The code that I am using employs .rm_rf but I get the same
results if I use
.rmdir instead.

$:.unshift File.join(File.dirname(FILE), “…”, “lib”)

require ‘test/unit’
require ‘fileutils’
require ‘mv2dir’

class Test_Mv2Dir < Test::Unit::TestCase

What are we going to test for?

#1. Test that instances test for valid directories and return

TRUE or FALSE as expected.

def test_dir
#-- a. define test directories
dir_test =
#-- b. clear them out:
dir_test.each do |dt|
puts dt
FileUtils.rm_rf(dt, :verbose => TRUE, :secure => TRUE)

FileUtils.rmdir(dt, :verbose => TRUE) rescue Errno::ENOENT



These are the results. ~/tmp/mv2dir/test/target exists before the run.
It is my intention that it be gone at the end of the run. It is not.
anyone point out to me what I am doing wrong?

ll ~/tmp/mv2dir/test/

rm -rf ~/tmp/mv2dir/test/target/

I can get this to work if I force :secure => FALSE but I do not see why
that should be necessary. None of the directories in the path
/home/byrnejb/tmp/mv2dir/test/target are world writeable. However,
unless I call FileUtils.rm_r(dt,:secure => FALSE) the directory is not
removed. Can someone explain to me what I am misunderstanding with
respect to the documentation?
