Question

I am trying to test a scenario where my app writes some files to a folder and that folder should then be removed after the test.

class TestDirectory < Test::Unit::TestCase
  def setup
    @target = "some/path"
    FileUtils.mkdir_p(@target)
  end

  def teardown
    FileUtils.rm_rf(@target)
  end

  test "remove directory" do
    #some tests
  end
end

But for some reason the folder does not get removed. I have also tried to set the secure option to false for FileUtils#rm_rf but that didn’t help either. Neither the parent nor the target folder are world writable, which could be an issue according to the documentation. I am running on Mac OS X Lion.

What am I doing wrong?

Answer 1

This code works for me:

require 'test/unit'
require 'fileutils'

class TestDirectory < Test::Unit::TestCase
  def setup
    @target = "/tmp/tmpfolder"
    FileUtils.mkdir_p(@target)
  end

  def teardown
    FileUtils.rm_rf(@target)
  end

  def test_something
    assert 1 + 1 == 2
  end
end
