Testing E-mail

[rfhayashi]

Hi, everyone

One of the things I like about Dependency Injection is how easy is to test the application. Specially when you use interfaces, it´s just a case of mocking the interface. I have an issue about testing sending e-mail. When you´re using Spring MailSender interface this is quite simple. But when you have to send MimeMessage's you have a problem, because JavaMail use classes instead of interfaces. How do you test e-mail in your applications? I've read about creating a mock smtp server, but I hope there is a more easy alternative.

Rgds,

I have been using the Dumbster mock SMTP server to test my email:

It is lightweight enough to be used with junit.

Have you looked at jMock's cglib extension which allows mocking concrete classes?

Thanks Patrick.

Dumbster is really cool.

I went through a lot of pain using Dumbster until I discovered a Dumbster replacement written by someone who got frustrated with the bugs in Dumbster.
Below is the comment I placed in the program I wrote that originally used Dumbster:

* The first version of this program used the open source Dumbster mock mail server.
* However a robust, well-written open source alternative was later found and the program was re-written to use org.subethamail.wiser.Wiser instead of Dumbster.
* Wiser, according to their web site, is quote, "a smart replacement for Dumbster".
