test a file upload using rspec - rails

Question

I want to test a file upload in rails, but am not sure how to do this.

Here is the controller code:

def uploadLicense
    #Create the license object

I haven't done this using RSpec, but I do have a Test::Unit test that does something similar for uploading a photo. I set up the uploaded file as an instance of ActionDispatch::Http::UploadedFile, as follows:

test "should create photo" do
  setup_file_upload
  assert_difference('Photo.count') do
    post :create, :photo => @photo.attributes
  end
  assert_redirected_to photo_path(assigns(:photo))
end


def setup_file_upload
  test_photo = ActionDispatch::Http::UploadedFile.new({
    :filename => 'test_photo_1.jpg',
    :type => 'image/jpeg',
    :tempfile => File.new("#{Rails.root}/test/fixtures/files/test_photo_1.jpg")
  })
  @photo = Photo.new(
    :title => 'Uploaded photo', 
    :description => 'Uploaded photo description', 
    :filename => test_photo, 
    :public => true)
end

Something similar might work for you also.
