The MUnit Coverage feature measures how much of a Mule application is executed by a set of MUnit
tests by counting event processors. Use it to track application, resource, and flow coverage metrics
and enforce quality standards.

- 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.

Coverage report runs only for EE edition runtimes. If your application has a `requiredProduct` of a
Mule CE runtime you will see the following message: **Coverage is a EE only feature and you’ve
selected to run over CE**. To run against an EE runtime see
[Specifying the Runtime Product](https://docs.mulesoft.com/munit/latest/munit-maven-plugin#specify-runtime-product).

The following is a coverage report sample in JSON format.  
Use the code callouts below to understand each field in the report:
