/**
 * @assertion Future<FileStat> stat(String path)
 * Asynchronously calls the operating system's stat() function on path. Returns
 * a Future which completes with a FileStat object containing the data returned
 * by stat(). If the call fails, completes the future with a FileStat object
 * with .type set to FileSystemEntityType.notFound and the other fields invalid.
 * @description Checks that if the call fails, completes the future with a
 * FileStat object with .type set to FileSystemEntityType.notFound and the
 * other fields invalid.
