About MUnit Coverage Reports

The MUnit Coverage feature provides a metric on how much of a Mule application has been executed by a set of MUnit tests.
This lets you obtain a quality metric for your application.

MUnit Coverage is based on the amount of event processors executed.
MUnit Coverage provides metrics for:

Application overall coverage: An average of the items below.
Resource coverage: Refers to each Mule configuration file under src/main/mule. Each of is considered a resource by MUnit Coverage.
Flow coverage: Refers to any of the following components: Flows, Sub-flows, and Batch jobs.

Coverage report runs only for EE edition runtimes

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

 "requiredResourceCoverage" : 30.0,
 "requiredFlowCoverage" : 25.0,
 "flowCount" : 3, (3)
 "processorCount" : 4, (4)
 "coveredProcessorCount": 4 (5)
 "files" : [ {
   "name": "sample.xml",
   "flowCount" : 1, (6)
   "coverage" : 100.0, (7)
   "processorCount" : 2, (8)

     "coveredProcessorCount" : 2

   } ],

}

1	Coverage percentage of the whole application.
2	Required coverages for application, resources and flow, if the user did not configure any value it defaults to -1.
3	Amount of flows in the application.
4	Amount of event processors in the application.
5	Amount of covered event processors.
6	Amount of flows in that file.
7	Coverage percentage of that file.
8	Amount of event processors in that file.
9	Contribution of that file to the coverage percentage of the whole application.
10	Name of the flow.
11	Type of the top level element. Other type of top level element in coverage is error-handler.
12	Coverage percentage of that flow.
13	Amount of event processors in that flow.
14	Name of that file.
