In this scenario, two additional pieces of setup are necessary:

<1> Declare dependencies using the `testReportAggregation` configuration
<2> Define a report of type `AggregateTestReport` which collects test data from unit test suites
<3> Optional: make aggregate test report generation part of the 'check' lifecycle phase

            testSuites.withType(JvmTestSuite.class).all(testSuite -> {
                reporting.getReports().create(testSuite.getName() + "AggregateTestReport", AggregateTestReport.class, report -> {
                    report.getTestType().convention(testSuite.getTestType());
                });
            });
        });
    }

import org.gradle.api.tasks.TaskProvider;
import org.gradle.api.tasks.testing.AggregateTestReport;
import org.gradle.api.tasks.testing.TestReport;
import org.gradle.language.base.plugins.LifecycleBasePlugin;

import javax.inject.Inject;

public abstract class DefaultAggregateTestReport implements AggregateTestReport {
    private final String name;
    private final TaskProvider<TestReport> reportTask;

    @Inject

    id 'test-report-aggregation'
}

dependencies {
    testReportAggregation project(':application') // <.>
}

// tag::create_report[]
reporting {
    reports {
        testAggregateTestReport(AggregateTestReport) { // <.>
            testType = TestSuiteType.UNIT_TEST
        }
    }
}
// end::create_report[]

tasks.named('check') {
    dependsOn tasks.named('testAggregateTestReport', TestReport) // <.>

}

dependencies {
    testReportAggregation(project(":application")) // <.>
}

// tag::create_report[]
reporting {
    reports {
        val testAggregateTestReport by creating(AggregateTestReport::class) { // <.>
            testType = TestSuiteType.UNIT_TEST
        }
    }
}
// end::create_report[]

tasks.check {
    dependsOn(tasks.named<TestReport>("testAggregateTestReport")) // <.>

When the project also applies the `jvm-test-suite` plugin, the following reporting objects are added for each test suite:

`__testSuite__AggregateTestReport` — link:{javadocPath}/org/gradle/api/tasks/testing/AggregateTestReport.html[AggregateTestReport]::
Creates a container to parameterize the link:{javadocPath}/org/gradle/api/attributes/TestSuiteType.html[TestSuiteType] value.

=== Manual report creation

                testReportAggregation project(":direct")
            }

            reporting {
                reports {
                    testAggregateTestReport(AggregateTestReport) {
                        testType = TestSuiteType.UNIT_TEST
                    }
                }
            }
