Как использовать MockServices для модульных тестов в Corda 4?

В Corda Enterprise 4.2 я пытаюсь завершить модульный тест, используя некоторые пользовательские таблицы JPA, и у меня возникла проблема со следующим кодом:

    serviceHub = MockServices(CordaX500Name.parse("O=OOO,L=Lambari,C=BR"))
    serviceHub.withEntityManager{
        val entityManager = this
        test = CustomJPABackedClass() 
        entityManager.persist(test)
    }

Этот код вызывает следующее исключение:

Как правильно использовать этот MockServices(или что-то еще) для создания быстрых модульных тестов?

ИЗМЕНИТЬ

После некоторых дополнительных исследований я нашел эти фрагменты кода в Corda OpenSource 4.2:

    override fun jdbcSession(): Connection = throw UnsupportedOperationException()

    override fun <T : Any> withEntityManager(block: EntityManager.() -> T): T {
        throw UnsupportedOperationException()
    }

    override fun withEntityManager(block: Consumer<EntityManager>) {
        throw UnsupportedOperationException()
    }

Прямо сейчас я знаю, почему я получаю указанное исключение. Но остается вопрос: как мне построить модульный тест? Хотелось бы не ждать 30 секунд при создании ноды для тестов…

ИЗМЕНИТЬ

Дальнейшие исследования привели к следующему коду:

package project
import net.corda.core.identity.CordaX500Name
import net.corda.core.internal.packageName
import net.corda.nodeapi.internal.persistence.CordaPersistence
import net.corda.testing.common.internal.testNetworkParameters
import net.corda.testing.core.TestIdentity
import net.corda.testing.node.MockNetwork
import net.corda.testing.node.MockNetworkParameters
import net.corda.testing.node.MockServices
import net.corda.testing.node.internal.enclosedCordapp
import net.corda.testing.node.makeTestIdentityService
import org.junit.Before
import org.junit.Test
//import net.corda.testing.node.MockServices
class CustomTest  {
    val myself = TestIdentity(CordaX500Name("Me", "London", "GB"))
    lateinit var mockNet: MockNetwork
    lateinit var services: MockServices
    lateinit var database: CordaPersistence
    @Before
    fun setUp() {
        mockNet = MockNetwork(MockNetworkParameters(cordappsForAllNodes = listOf(enclosedCordapp())))
        val (db, mockServices) = MockServices.makeTestDatabaseAndMockServices(
                cordappPackages = listOf(javaClass.packageName),
                identityService = makeTestIdentityService(myself.identity),
                initialIdentity = myself,
                networkParameters = testNetworkParameters(minimumPlatformVersion = 4)
        )
        services = mockServices
        database = db
    }
    @Test
    fun actualTest() {
        println("mockNet  : $mockNet")
        println("services : $services")
        println("database : $database")
    }
}

И к следующему исключению:

Есть мысли по этому поводу?
