我们有一个SpringBoot2.2.0 testing应用程序，我们正在使用JUnit 5测试类使用WireMock进行测试。该测试在本地运行良好，但在我们的Jenkins上，在测试成功运行后，它在“已在使用的地址”消息中失败。

这里是我们来自pom.xml的春季依赖项

所以我们的测试非常简单，如下所示：

代码语言：javascript
复制
@ExtendWith(SpringExtension.class)
@SpringBootTest
@ActiveProfiles("test")
@AutoConfigureWireMock(port = 0)
@Import(TestChannelBinderConfiguration.class)
class OurTestClass {
    @Autowired
    private OurDataCache cache;
    @Autowired
    private InputDestination source;
    @Autowired
    private OutputDestination target;

    @BeforeEach
    void setupApi() throws IOException, URISyntaxException {
        stubFor(get("/endpoint")
                .willReturn(aResponse()
                        .withStatus(200)
                        .withHeader("Content-Type", MediaType.APPLICATION_JSON_VALUE)
                        .withBody(data())
                )
        );
    }

    @Test
    void sampleTest() {
        String messageContent = loadResourceFileAsMessage("messageIn.json");
        String expectedOutMessage = loadResourceFileAsMessage("messageOut.json");

        Message<byte[]> message = new GenericMessage<>(messageContent.getBytes());

        source.send(message);

        Message<byte[]> received = target.receive();
        assertThat(received, notNullValue());

        assertThat(new String(received.getPayload()), equalTo(expectedOutMessage.replace(" ", "")));
    }
}

同样，这在本地运行良好，在Jenkins上，实际的测试用例通过了，但是我们得到了错误：

我还为Spring WireMockConfiguration启用了调试日志记录，很有趣的是，构建成功了。它确实提到了“重新设置下一个测试的映射以重新启动它们，在测试之后，当在随机端口上运行的新服务器重用相同的上下文时，这是必要的”。

这使我认为这可能是某种比赛条件，但我不能说，我完全掌握总体设置。

任何指示都会有帮助。

这是一个众所周知的问题：https://github.com/spring-cloud/spring-cloud-contract/issues/665

在使用@DirtiesContext或在src/test/resources/ spring.test.context.cache.maxSize=1 (https://docs.spring.io/spring/docs/current/spring-framework-reference/testing.html#testcontext-ctx-management-caching)中设置spring.test.context.cache.maxSize=1的所有测试中，都必须使用spring.test.context.cache.maxSize=1。

Spring-Boot：2.5.4

使用@DirtiesContext是我们最后的资源。

备注：使用随机端口

以下任一项：

作为注释属性传递的@AutoConfigureWireMock(port = 0).

备注：记住默认端口是8080，因此可能与本地服务或其他在本地运行的端口冲突(如果server.port有default value / not specified)。

wiremock.server.port=0.

  • 或in application-test.properties/.yml：

我善意地建议最后一个，因为它更易于维护，在一个地方保持配置需要查询。

可以在多个端点(第三方或本地服务)上重用这一点：

代码语言：javascript

app:
  endpoints:
    local-service: http://localhost:${wiremock.server.port}/some/path
    external-service: http://localhost:${wiremock.server.port}/another/path
