WebTestClient配置了错误的端口

Question

我在斯波克写过集成测试。已将Spring Boot上下文配置为随机端口。Documantation声称sprig应该为我注入正确配置的WebTestClient实例，但是当我试图通过这些“自动配置的实例”进行调用时，我有下面给出的错误：

Caused by: io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information: localhost/127.0.0.1:8080
    Suppressed: reactor.core.publisher.FluxOnAssembly$OnAssemblyException: 
Error has been observed at the following site(s):
    |_ checkpoint ⇢ Request to POST http://localhost:8080/sign-up [DefaultWebClient]

下面是我的代码：BaseIntegrationTest

@SpringBootTest(webEnvironment = RANDOM_PORT, classes= Application.class)
@ContextConfiguration
@EnableConfigurationProperties
abstract class BaseIntegrationSpec extends Specification {

使用WebTestClient类：

@Component
class WebTestClientWrapper {

    @Autowired
    private WebTestClient webTestClient

    @Autowired
    private ObjectMapper objectMapper

Answer 1

启动测试时，确保localhost:8080上的服务器已在运行。WebTestClient假定外部服务器绑定到服务器时正在运行。
