- 9. 9 MUnit is Anypoint Platform’s dedicated unit testing tool specifically designed for Mule applications. It runs inside a Mule runtime, manually in Anypoint Studio, and automatically as part of the Maven-based CI/CD build process. MUnit is designed to create structural test cases as Mule flows. That means you can use components on top of MUnit and MUnit tool modules. What is Munit?
- 10. 10 Different Approach of Writing Munit ● Munit Test Recorder ● Manually
- 11. 11 Limitations with Test Recorder The test recorder is limited in the following ways when you create MUnit tests: ● You cannot create tests for flows with Mule errors raised inside the flow or already existing in the incoming event, not even if they are handled by an on error continue error handler. ● A recorded flow execution ends successfully, but the result does not reach its destination because the application is killed. ● Your validations fail every time your test runs if you configure Spy or Assert processors to assert values for random data, time-dependent information (such as timestamps), or values resulting from parallel processes, because those values change in every execution. ● Mocking values resulting from parallel processes causes a mixture of real and mocked data that compromises the execution of the processors that follow in your test. ● Although the recorder supports data iteration in the flow, such as recursivity or loops, it does not support cases in which the structure of the data being tested changes inside the iteration. ● The recorder does not support mocking a message before or inside a Foreach

- 13. 13 Executing Munit Suite ● From Studio ● From cmd (mvn clean test)
- 14. 14 Munit Coverage The MUnit Coverage feature provides a measurement of how much of a Mule application has been executed by a set of MUnit tests by counting the amount of event processors executed.This allows you to obtain a quality standard for your application, and provides metrics for: ● Application overall coverage: An average of the items below. ● Resource coverage: Refers to each Mule configuration file under src/main/mule. ● Flow coverage: Refers to any of the following components: Flows, Sub-flows, and Batch jobs.
- 15. 15 ● <ignoreFlows> <ignoreFlow>FlowName</ignoreFlow> </ignoreFlows> ● <ignoreFiles> <ignoreFile>FileNamet.xml</ignoreFile> </ignoreFiles> Ignoring Files or Flow
- 17. Batch Processing Mule batch processing components are designed for reliable, asynchronous processing of larger-than- memory data sets. The components are the Batch Job, Batch Step, and Batch Aggregator. The Batch Job component automatically splits source data and stores it into persistent queues, which makes it possible to process large data sets while providing reliability. In the event that the application is re- deployed or Mule crashes, the job execution is able to resume at the point it stopped. 17 Phases: ● Load and Dispatch ● Process ● On Complete
