Why?

While working on a Rails project, I found myself wanting to write tests around the ability to upload a feed file to an external FTP server. After reading about rumbster (https://github.com/sr/rumbster), I really wanted something like that for FTP. At the time, I was reduced to stubbing Net::FTP.

FakeFtp is a single-client server that accepts a minimum of FTP commands necessary for file upload. Files are not currently stored by the server, but are tracked in the server's :files accessor.

Usage

require 'fake_ftp'
require 'net/ftp'

server = FakeFtp::Server.new(21212, 21213)
## 21212 is the control port, which is used by FTP for the primary connection
## 21213 is the data port, used in FTP passive mode to send file contents
server.start

ftp = Net::FTP.new
ftp.connect('127.0.0.1', 21212)
ftp.login('user', 'password')
ftp.passive = true
ftp.put('/dir/to/some_file.txt')
ftp.close

server.files.should include('some_file.txt')
server.file('some_file.txt').bytes.should == 35

server.stop
