I'm trying to write a unit test to check whether or not an outbound message was triggered via a workflow. For instance, I have a class that will set a field on a contact record. The workflow rule is setup to evaluate the field on the contact and if it matches some criteria, it will queue an outbound message. I'm curious to see if there is a way to test if limits were invoked as a result of the workflow rule being kicked off. Kind of similar to how you can test email messages being sent. Perhaps they are the same limits?
