Standalone dummy FTP server. Run either within the same JVM as test code or in a different JVM.
Implements common FTP server commands. See FTP Commands and CommandHandlers.
Supports active and passive mode data transfers.
Works out of the box with reasonable defaults: success reply codes and empty data.
Easy to configure command handlers for individual FTP server commands to return success/failure reply codes and custom data.
Can verify expected FTP server command invocations.
Easy to implement command handlers for other commands or replace existing command handlers.
Use a dynamically chosen free port number for the server control port instead of using the default (21) or hard-coding some other value (set the serverControlPort property of the server to 0).
Fully supports configuration within the Spring Framework.
Can be used to test FTP client code written in any language
