About Assert That Event Processor

The Assert That Event Processor allows you to run assertions in order to validate the state of a Mule Event’s content.
This Event Processor can be used to validate the Mule Event after the production code runs.

For example, to assert that a payload is equal to a certain value, you can configure the Assert-That processor using the equalTo() matcher.

  message="The payload should be β€˜example’"/>

Or you can also check if the payload is null using the nullValue() matcher.

  message="The payload is null"/>

If these assertion fails, the processor throws a java.lang.AssertionError.
