/**
 * @assertion void writeAsBytesSync(
 * List<int> bytes, {
 * FileMode mode: FileMode.write,
 * bool flush: false
 * })
 * Synchronously write a list of bytes to a file.
 *
 * Opens the file, writes the list of bytes to it and closes the file.
 *
 * By default writeAsBytesSync creates the file for writing and truncates the
 * file if it already exists. In order to append the bytes to an existing file,
 * pass FileMode.append as the optional mode parameter.
 *
 * If the flush argument is set to true data written will be flushed to the file
 * system before returning.
 *
 * Throws a FileSystemException if the operation fails.
 * @description Checks that in a FileMode.write writeAsBytesSync creates the
 * file for writing and truncates the file if it already exists
