Hi,
I found this test helper on the Rails wiki, works like a charm.
# returns an uploaded screenshot you can use to test file uploads in your controllers def uploaded_screenshot uploaded_file("#{File.expand_path(RAILS_ROOT)}/test/fixtures/ samplescreenshot.jpg", "image/jpeg") end
# returns an uploaded movie you can use to test file uploads in your controllers def uploaded_movie uploaded_file("#{File.expand_path(RAILS_ROOT)}/test/fixtures/ samplemovie.flv", "video/flv") end
# get us an object that represents an uploaded file def uploaded_file(path, content_type="application/octet-stream", filename=nil) filename ||= File.basename(path) t = Tempfile.new(filename) FileUtils.copy_file(path, t.path) (class << t; self; end;).class_eval do alias local_path path define_method(:original_filename) { filename } define_method(:content_type) { content_type } end return t end
put that in test_helper.rb
Then in your controller test, put this:
# update a fragment # uses test helper uploaded_screenshot() to simulate a file upload def test_should_update_fragment put :update, :id => 1, :fragment => { :title => 'new f' }, :screenshot => { :uploaded_data => uploaded_screenshot }
assert_redirected_to fragment_path(assigns(:fragment)), assigns(:fragment).errors.inspect end
