Setup Integration Tests for Multi Project Play Framework App

I have a Play Application that has multiple projects(service, service-impl, entities etc), each project is managed by maven pom. It also has a service-gateway project but managed by sbt, this manages request and response. The structure of the project looks like this

entities/
    src/
    pom.xml
service/
    src/
    pom.xml
service-impl/
    src/
    pom.xml
controller/
    src/
    pom.xml
service-gateway/
    app/
    build.sbt

I would like to setup Integration tests to test my services and controllers. The issue is I can't inject an EntityManager to allow repository access and also my custom services are not injected. Here is my test code

public class DefaultDriverServiceTest {

    @Inject
    DriverService driverService;

    @Inject
    JPAApi jPAApi;

    @Test
    public void find() throws Exception {

        JpaDriver jpaDriver = new JpaDriver();
        jpaDriver.setDateCreated(new Date());
        jpaDriver.setDriverId(UUID.randomUUID().toString());
        jpaDriver.setUsername("username");
        jpaDriver.setPassword("password");
        jpaDriver.setOnlineStatus("online");

        jPAApi.em().persist(jpaDriver);

        JpaDriver driver = driverService.find(jpaDriver.getDriverId());

        assertEquals(jpaDriver.getDriverId(), "4");
    }
}

I have read a lot on Play's website on setting up tests and actually tried a lot of stuff I found online but still no luck with testing my services and controllers. Any help would be much appreciated
