Assert That Event Processor
The Assert That event processor allows you to run assertions to validate the state of a Mule event’s content. You can use the Assert That processor to validate the Mule event after the production code runs.
The Assert That processor uses a set of DataWeave functions called
MUnit matchers to define the assertion conditions for any value in an expression.
For example, to assert that a payload is equal to a certain value, configure the Assert That processor using the
Or you can also check if the payload is null using the
<munit-tools:assert-that expression="#[payload]" is="#[MunitTools::nullValue()]" message="The payload should be null"/>
See MUnit Matchers for more information.
If these assertion fails, the processor throws a
