Here, we add an additional source set _integrationTest_ with a `module-info.java`.

```
src
└── integrationTest
    └── java
        └── module-info.java
```

We effectively declare a second module that is only used for testing.

        executer.inDirectory(dslDir)

        when:
        def result = succeeds("test", "integrationTest")

        then:
        result.assertTaskOrder(":test", ":integrationTest")

        and:
        assertTestsRunCount(
            getTestResultsFileAsXml(dslDir, "org.gradle.PersonIntTest", "integrationTest"),
            1)

        where:
        dsl << ['groovy', 'kotlin']
    }

Consequently, source code directories for other test types should follow a similar pattern:
