The document discusses testing a Mule application using the MUnit test suite. It describes creating a Mule project with HTTP listener and message processors, then validating it with MUnit tests in Anypoint Studio. Tests are added to assert payloads and add mocks. The tests are then executed from Anypoint Studio and results are displayed, with an option to generate a report.

2. Testing Mule Application Using MUnit Test Suite
Topics :
• Create Mule Project
• Define Message Processors
• Validate Test cases using MUnit
Pre-requisites :
• Basic under standing of Mule ESB
• JDK 1.8 or above
• Anypoint Studio v 6.0.3 or above
• Mule Server v 3.8.0 EE or above

3. Create Mule Project : mavenproject
- Define HTTP Listener configuration
- Add Message Processor – Set Payload
- Add Message Processor – Logger
Setting :

4. Validate pom.xml:
- Add MUnit for selected flow :
- Creation of MUnit Tests:
- MUnit test studio plugin is available with the Anypoint Studio and no need to download explicitly.
- To create tests, Click File -> MUnit and select the flow which needs to be tested.
- In this case, it will be testing the “mavenprojectFlow”. Click the “Finish” button.
- You will see that Studio has added the plugin for MUnit and it has “runCoverage” set as true.
- This means when you run the MUnit test suite, it calculates the coverage for that flow.

5. Add Tests From Anypoint Studio :
- Add Assert Payload
- Add Mock

6. Execute Tests From Anypoint Studio :
- Right click on the Message Flow area of the test suite XML created.
- It will find the XMLs in the folder “src/test/munit” in the “mavenproject” project.
- Double click on that file and then right click and click “Run MUnit Suite”.
- Once it completes running, it will display the results in the MUnit window as below:
- Click on “Generate Report”, it will generate report as below.
