Optimizing API Testing with MUnit Coverage Reports in Studio
Run a coverage report from Anypoint Studio to obtain detailed insights of the effectiveness of MUnit tests on your Mule applications.
The following configurations apply when you execute your MUnit tests in Studio. They don’t apply when running tests from Maven in a CI/CD environment. To run coverage reports from Maven, see Maven Configuration for Coverage.
Enable Coverage Reports in Anypoint Studio
To see which flows, and which percentage of event processors in those flows the test covers, click the Coverage button:
The Overall coverage value represents the percentage of Mule application event processors that the MUnit test executes.
Click Generate Report to get the report that details the flows and event processors in the Mule configuration files included in the MUnit test.

Disable Coverage Reports
Disable the coverage calculation from your project run configuration so you test your flow without a coverage report.
Right-click Package Explorer and choose Run As > Run Configurations. Select your MUnit run configuration file to access your suite configuration, and deselect the Run coverage option in your coverage settings.
Exclude XML Files from MUnit Coverage Report
Exclude one or more XML files from an MUnit Coverage report when testing your application. For example, exclude a third-party XML file that doesn’t comply with your quality standards to improve your final report score.
