SpringBoot 2 and SDN 5 Unit Test hangs after start

Question

I'm trying to migrate to SpringBoot 2 and SDN 5, working on just getting a unit test running. My test code:

@SpringBootTest
@ContextConfiguration(classes = com.playerscoach.auth.context.PersistenceContext.class)
@RunWith(SpringRunner.class)
public class AthleteRepositoryTest {
    private static final Logger log = LoggerFactory.getLogger(AthleteRepositoryTest.class);
    @Autowired
    UserRepository userRepository;
    @Autowired
    private Session session;
    @Autowired
    private AthleteRepository athleteRepo;
    private GraphDatabaseService graphDb;
    private GraphAwareRuntime runtime;

    @Before
    public void setUp() {

        GraphDatabaseService graphDb = new GraphDatabaseFactory()
                .newEmbeddedDatabase(new File("var/graphDb"));

        GraphAwareRuntime runtime = GraphAwareRuntimeFactory
                .createRuntime(graphDb);

    }

    @After
    public void tearDown() {
        session.purgeDatabase();
    }

    /**
     * Test of findByTitle method, of class MovieRepository.
     */
    @Test
    public void testFindByEmail() {
        Athlete athlete = new Athlete.Builder()
                .firstName("Alper")
                .lastName("Akture")
                .emailAddress("alper@test.com")
                .password("password").build();
        athleteRepo.save(athlete);
        String email = "alper@test.com";
        Collection<Athlete> result = athleteRepo.findByEmailAddress(email);
        assertThat(result, notNullValue());
        assertThat(result.iterator().next().getPassword(), is("password"));
    }

    @Test
    public void testFindByLastName() {

        String lastName = "Akture";
        Collection<Athlete> result = athleteRepo.findByLastName(lastName);
        assertThat(result, notNullValue());
        assertThat(result.iterator().next().getPassword(), is("password"));
    }

}

My repository:

    public interface AthleteRepository extends Neo4jRepository<Athlete, Long> {

    Collection<Athlete> findByEmailAddress(@Param("emailAddress") String emailAddress);

    Collection<Athlete> findByLastName(@Param("lastName") String lastName);

    @Query("MATCH (a:Athlete) WHERE a.emailAddress =~ ('(?i).*'+{emailAddress}+'.*') RETURN a")
    Collection<Athlete> findByEmailContaining(@Param("emailAddress") String emailAddress);

}

When I run the test, it hangs with the last line output in the log file:

07:53:03.526 [main] DEBUG org.springframework.boot.context.logging.ClasspathLoggingApplicationListener - Application failed to start with classpath:

with a dump of the entire classpath.

Any idea where I went wrong?
