=head1 DESCRIPTION

Test::Mock::Net::FTP is Mock Object for Net::FTP. This module behave like FTP server, but only use local filesystem.(not using socket).

=head1 NOTICE

=over 4

=item
This module is implemented all Net::FTP's methods, but some methods are 'do nothing' currently. These methods behavior may be changed in future release.

=item
This module works in only Unix-like systems(does not work in MS-Windows).

=item
Some errors are not reproduced in this module.

=item
If you don't like default implementation of methods in this module, you can use override (or RT to me :-)
