We use heavily JUnit Tests for testing our BPMNs.  
Some BPMNs use the Activiti MailTask. This work’s great on our real environment (where we have a mail server), but for the JUnit Tests, we would like to disable the mail functionality.

Is there a way to do this?

Björn

Hi,

isn’t it possible to run the unit tests with a ‘test engine config’ where the mail server is stubbed?

Yes, we have a test engine config, but how do I get the mail server stubbed? If I leave the mail configuration blank (ProcessEngineConfiguration), I get an Connection Refused Exception

Hi.

The actual logic for sending the email is the _MailActivityBehavior_ so you could mock that in your tests.  
If you’re really want to unit test in stead of a integration test.

But perhaps better (and easier) is to start a simple mail server in your tests.  
Take a look how we do it when testing the MailTask.

Hope this helps.
