# you'd get from the standard library CGI module in a multipart
# request. This means you can use an ActionController::TestUploadedFile
# object in the params of a test request in order to simulate
# a file upload.
#
# Usage example, within a functional test:
# post :change_avatar, :avatar => ActionController::TestUploadedFile.new(ActionController::TestCase.fixture_path + '/files/spongebob.png', 'image/png')
#
# Pass a true third parameter to ensure the uploaded file is opened in binary mode (only required for Windows):
# post :change_avatar, :avatar => ActionController::TestUploadedFile.new(ActionController::TestCase.fixture_path + '/files/spongebob.png', 'image/png', :binary)
