 * @assertion UriData.fromString(

 *  Map<String, String> parameters,

 * Creates a data: URI containing the content string.
 * Equivalent to new Uri.dataFromString(...).data, but may be more efficient if
 * the uri itself isn't used.
 * @description Checks that this constructor creates an expected UriData. Test
