Hi,
i followed this page (https://portal.liferay.dev/docs/7-1/tutorials/-/knowledge_base/t/injecting-service-components-into-tests) to create a simple integration test for my osgi service.
In my gradle i have imported this dependencies:

testCompile group: 'junit', name: 'junit', version: '4.12'
testCompile group: "com.liferay.portal", name: "com.liferay.portal.kernel"
testCompile group: 'com.liferay.portal', name: 'com.liferay.portal.test.integration'
testCompile group: "com.liferay.portal", name: "com.liferay.portal.test"

My integration test code is very simple:

public class TestIntegration {
    private static Log _log = LogFactoryUtil.getLog(TestIntegration.class);
    @ClassRule
    @Rule
    public static final AggregateTestRule aggregateTestRule = new LiferayIntegrationTestRule();
    
    @Inject(type = MyService.class)
    private static MyService _myService;    
    @Before
    public void setUp() {
        _log.info("Init TestIntegration");
    }
    @Test
    public void schedulerDescription() {
        _log.info("TestIntegration");
    }   
}

If i do a gradle build, this test is never run, but if i launch an jUnit test i have this trace:
