The user must also declare one or more reports of type `JacocoCoverageReport`.  Each report instance specifies a `testType` property, used to match the test suite producing the coverage data.  A `JacocoReport` task is synthesized for each user-defined report and performs the aggregation.  Invoking this task will cause tests to be executed in the dependent projects of the `jacocoAggregation` configuration.

For the default test suite named 'test', no additional configuration is necessary.  The aggregated reports and their backing tasks of type `JacocoReport` are synthesized based on the test suites existing in the `application` project.  Test suites having identical `testType` properties will be aggregated.

Running the tests and generate the report:

            }
            val testTaskName = "test${sourceName.capitalize()}UnitTest"
            // Create coverage task of form("testFlavorTypeCoverage" depending on("testFlavorTypeUnitTest"
            tasks.register<JacocoReport>("${testTaskName}Coverage") {
                dependsOn(testTaskName)
                group = "Reporting"
                description = "Generate Jacoco coverage reports on the ${sourceName.capitalize()} build."
