Assert Equals
The Assert Equals processor allows you to run assertions in order to validate the state of a Mule Event’s content. This 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-Equals processor the following way:
<munit-tools:assert-equals
actual="#[payload]"
expected="#[2]"
message="The payload should be 2"/>If the expected attribute is a String, you can specify the literal value without requiring an expression.
<munit-tools:assert-equals
actual="#[payload]"
expected="Example"
message="The payload should be 'Example'"/>If this assertion fails, the processor throws a java.lang.AssertionError.
