我想模拟我的服务类并调用它从抽象类和接口继承的任何方法，就像它们属于服务一样。不幸的是，当我模拟服务并从抽象类调用方法时，mockito 会调用抽象类中的真实方法。是否有可能以某种方式完全模拟服务类？

界面：

interface MessageProducer<T> {
    fun sendMessage(data: T)
}

抽象类：

abstract class AuditableMessage<T>(
    private val auditService: AuditService
) : MessageProducer<T> {
    protected abstract val auditPoint: String

    fun sendAuditJsonMessage(data: T) {
        auditService.auditJson(auditPoint, data as Any)
        sendMessage(data)
    }
)

混凝土弹簧服务

@Service
class ClientProducer(
    private val kafkaProducer: KafkaTemplate<String, String>,
    auditService: AuditService
) : AuditableMessage<String>(auditService) {

    override val auditPoint: String = "MY_AUDIT_POINT"

    override fun sendMessage(data: String) {
        kafkaProducer.sendDefault(data)
    }
}

测试班

@ExtendWith(MockitoExtension::class)
internal class ClientRequestServiceTest {
    @Mock
    lateinit var clientProducer: clientProducer
    @InjectMocks
    lateinit var clientRequestService: ClientRequestService
    @Captor
    lateinit var requestCaptor: ArgumentCaptor<String>

    @Test
    fun `test createClient creates request and calls send message`() {
        ...
        clientRequestService.createClient(clientData)
        verify(clientProducer).sendAvroAuditJsonMessage(capture(requestCaptor))
    }
}

更新测试用例： 我有一个注入 ClientProducer 并调用其方法的默认服务。

@Service
class ClientRequestService(
    private val primeClientProducer: clientProducer
) {

    fun createClient(clientData: PrimeAddClientInput) {
        try {
            clientProducer.sendAvroAuditJsonMessage("TEST")
        } catch (e: Exception) {
            log.error {""}
            throw e
        }
    }

@ExtendWith(MockitoExtension::class)
internal class ClientRequestServiceTest {

    @Mock
    lateinit var primeClientProducer: PrimeClientProducer
    @InjectMocks
    lateinit var clientRequestService: ClientRequestService
    @Captor
    lateinit var requestCaptor: ArgumentCaptor<String>

    @Test
    fun `test createClient creates request and calls send message`() {
        val clientData = easyRandom.nextObject(String::class.java)

        clientRequestService.createClient(clientData)

        verify(primeClientProducer).sendAvroAuditJsonMessage(capture(requestCaptor))
        val request = requestCaptor.value
        verify("TEST", request)
   }
}

Exception:
java.lang.NullPointerException
    at code.AuditService.auditJson$default(AuditService.kt:41)
    at code.AuditableMessage.sendAvroAuditJsonMessage(AuditableMessage.kt:23)
    at code.ClientRequestService.createClient(ClientRequestService.kt:20)

所以它基本上调用 auditService.auditJson(...) 但它不应该

我在依赖项中有一些不匹配。现在它可以正常工作
