Thanks for contributing an answer to Stack Overflow! Assume that you have an HTTP requester in your flow with an On-Error scope that catches any connectivity errors and returns a custom payload if the connection fails: You can assert that every time the HTTP request fails, your application returns your custom payload: You cannot return all known error types of a Mule application. For example, to assert that a payload is equal to a certain value, you can configure the Assert-That processor using the equalTo() matcher.

The image above provides the processor as db:select and attribute as config-ref by looking into database configuration. It provides a full suite of integration and unit test capabilities,. It will raise errors and use variables that are assigned in the set-event from the YAML configuration file to transform the expected payload in the HTTP error scenario. Using this worked . This means that if I try to run the test cases individually, they will do it successfully, but when all the suite is run, the first case executes OK but the subsequent ones fail. Assert that the returned payload is the one you set inside the On-error scope. You can then use the readUrl DataWeave function to read the mapping file: Finally, you can configure a then-return element to define the type of response the mocked processor should return. Media Type: Defines the mime type of the message. It accepts MEL expressions. Instead of returning a mocking result, it executes the flow and returns the connector response payload.
