/**
 * @assertion void writeAsStringSync(
 *  String contents, {
 *  FileMode mode: FileMode.write,
 *  Encoding encoding: utf8,
 *  bool flush: false
 *  })
 * Synchronously write a string to a file.
 *
 * Opens the file, writes the string in the given encoding, and closes the file.
 *
 * By default writeAsStringSync 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.read a FileSystemException is thrown.
