Below is my Batch flow, where the batch job has multiple complex batch steps, and each of them has different steps of transformation of data. Test one thing at a time. The Assert That processor uses a set of DataWeave functions called MUnit matchers to define the assertion conditions for any value in an expression. To execute a subset of cases, the MUnit tests can be executed using the Maven Plugin. MUnit Matchers. This message processor is normally used at the beginning of an MUnit test, to define the first message to send to the flow being tested. The application produces an output similar to below: %dw 2.0 output application/json --- { message: "Hello world" } The sample payload below to compare for the MUnit test is saved in a file: {"message":"Hello world"} 2. MUnit matches are a set of DataWeave functions to define assertion conditions for any value in an expression. Repeat step 3 with the next building block with a breakpoint, if any. Bellow you will find a few tips on writing successful MUnit tests and some examples. The assertion that I would like to achieve is to check whether the status code matches 200 and if custom response headers matches my name The actual test results to the desired output: MUnit is a Mule application testing framework that enables to formulate automated tests for mule integrations and API. Repeat step 3 with the next building block with a breakpoint, if any. MUnit tests are a good fit within the Mule toolset; you can use the same graphical technique for designing flows and tests. it should only focus to validate a specific function or processor of a flow.
