Basically, MUnit replaces the actual behavior of message processor with the . 2. 4. The Munit Coverage report does not reflect this in the report. Notice the output format. But, the Munit Studio has a limitation with this. This is the main flow where Munit is created for testing the application and this flow contains Http listener, MySQL database, Transform Message, logger and Set Payload. Instead of using Assert Payload on JSON/XML, you can parse it with DataWeave to Java and check each attribute with Assert Equals. But, Mule 4 has two categories: Munit and Munit tools. The above request is a POST endpoint that will create record in Salesforce. . Now for the MUnit we will have to select the flow and right click on it and then select MUnit and then Create MUnit for that flow as shown below: This we will create an MUnit test suite, which will be present in src/test/munit as shown below: Now we have to Search for the Mock When that is in the mule . Click on pick processor (this option is not available in version 4.1.x , still you can maually write doc:name and config-ref for identification of processor). Scenario: The underlying concept here is to capture a change requirement scenario. Basically, MUnit replaces the actual behavior of message processor with the behavior defined by the user. I just have to put set-message, my functional flow-ref and any following assertions into a subflow and repeat that using, for instance, a for-each scope. Step 2: Now you will see a new file being created under src/test/munit folder, which contains a blank test case as shown below: You can change the name of the test suite and the flow name as you wish.
