What is the easiest way to mock an IMAP or POP server for unit tests? [duplicate]

Answer 1

I would suggest to embed a pure Java IMAP/POP server in your test code.

For that, you have numerous possibilities, including:

• Write your own IMAP mock using Javamail
• Use Dwarf mail server
• Use JMock to emulate the various interfaces of your mail server (after all, it must have an interface, no ?)
