/**
 * @assertion Future<RandomAccessFile> open({FileMode mode: FileMode.read})
 * Open the file for random access operations. Returns a
 * Future<RandomAccessFile> that completes with the opened random access file.
 * RandomAccessFiles must be closed using the RandomAccessFile.close method.
 *
 * Files can be opened in three modes:
 * FileMode.read: open the file for reading.
 * FileMode.write: open the file for both reading and writing and truncate the
 * file to length zero. If the file does not exist the file is created.
 *
 * FileMode.append: same as FileMode.write except that the file is not
 * truncated.
 * @description Checks that if file path is wrong then this operation fails
