Spock模拟/存根RESTAPI

Question

我在micronaut中有以下接口来执行HTTP POST请求：

@Client("shoppingCenter")
@SubscriptionKey
interface ApiClient {
  @Post("/shoppingcenter/api/Order")
  OrderResponse createResponse(@Body OrderRequest request);
}

我有一个调用接口的类：

public class OrderService {
  @Inject
  ApiClient apiClient;

  public void sendNewOrder(String item) {
    OrderRequest request = new OrderRequest.builder() 
    // ..builder code
    OrderResponse response = apiClient.createResponse(request);
  }
}

我想在我的spock测试中模拟/存根API调用，我尝试了以下方法：

apiClient.createResponse(request) >> new OrderResponse("orderID")

class OrderServiceSpec extends ApplicationContextSpecification implements RepositoriesFixture, LeakageDetector {
  @Subject
  @Shared
  OrderService OrderService = applicationContext.getBean(OrderService)

  def 'test "sendNewOrder"' (){
    given: 'Item'
    ApiClient apiClient = Stub()
    OrderRequest request = new OrderRequest();
    apiClient.createResponse(request) >> new OrderResponse("orderID")

    when:
    OrderService.sendNewOrder("someItem")

    then:
    noExceptionThrown()

    cleanup:
    //...
  }
} 

然而，我得到的错误：

Expected no exception to be thrown, but got 'io.micronaut.discovery.exceptions.NoAvailableServiceException'

    at com.daimler.api.notification.NotificationServiceSpec.test "sendNewOrder"(OrderServiceSpec.groovy:46)

我认为，你应该阅读一些基本的Micronaut留档，例如。Micronaut测试-使用Spock测试，尤其是“使用Spock Mocks”部分。就像我在评论中说的，我以前从未使用过Micronaut。但是我能够在10秒内通过谷歌micronaut test mock找到这个。
