+# Add the methods +upload+, the <tt>setup_file_fixtures</tt> and
+# <tt>teardown_file_fixtures</tt> to the class Test::Unit::TestCase.
+class Test::Unit::TestCase
+  # Returns a +Tempfile+ object as it would have been generated on file upload.
+  # Use this method to create the parameters when emulating form posts with 
+  # file fields.
+  #
+  # === Example:
+  #
+  #    def test_file_column_post
+  #      entry = { :title => 'foo', :file => upload('/tmp/foo.txt')}
+  #      post :upload, :entry => entry
+  #  
+  #      # ...
+  #    end
+  #
+  # === Parameters
+  #
+  # * <tt>path</tt> The path to the file to upload.
+  # * <tt>content_type</tt> The MIME type of the file. If it is <tt>:guess</tt>,
+  #   the method will try to guess it.
+  def upload(path, content_type=:guess, type=:tempfile)
+    if content_type == :guess
+      case path
+      when /\.jpg$/ then content_type = "image/jpeg"
+      when /\.png$/ then content_type = "image/png"

+  # Copies the fixture files from "RAILS_ROOT/test/fixtures/file_column" into
+  # the temporary storage directory used for testing
+  # ("RAILS_ROOT/test/tmp/file_column"). Call this method in your
+  # <tt>setup</tt> methods to get the file fixtures (images, for example) into
+  # the directory used by file_column in testing.
+  #
+  # Note that the files and directories in the "fixtures/file_column" directory 
+  # must have the same structure as you would expect in your "/public" directory
+  # after uploading with FileColumn.
+  #
+  # For example, the directory structure could look like this:
+  #
+  #   test/fixtures/file_column/
+  #   `-- container
+  #       |-- first_image
+  #       |   |-- 1
+  #       |   |   `-- image1.jpg
+  #       |   `-- tmp
+  #       `-- second_image
+  #           |-- 1
+  #           |   `-- image2.jpg
+  #           `-- tmp
+  #
+  # Your fixture file for this one "container" class fixture could look like this:
+  #
+  #   first:
+  #     id:           1
+  #     first_image:  image1.jpg
+  #     second_image: image1.jpg
+  #
+  # A usage example:
+  #
+  #  def setup
+  #    setup_fixture_files
+  #
+  #    # ...
+  #  end

+    
+    FileUtils.mkdir_p tmp_path unless File.exists?(tmp_path)
+    FileUtils.cp_r file_fixtures, tmp_path
+  end
+  
+  # Removes the directory "RAILS_ROOT/test/tmp/file_column/" so the files
+  # copied on test startup are removed. Call this in your unit test's +teardown+
+  # method.
+  #
+  # A usage example:
+  #
+  #  def teardown
+  #    teardown_fixture_files
+  #
+  #    # ...
+  #  end
