Jenkins 中 Junit 中的 WireMock - BindException：地址已在使用中

Question

我有一些使用 WireMock 的 Junit 测试。本地测试通过，但在詹金斯我得到一个错误 java.lang.RuntimeException: java.net.BindException: Address already in use

在 WireMock 配置中，我设置了 dynamicHttpsPort()（根据文档“在启动时随机分配 HTTPS 端口”）并且它在本地工作，但在 Jenkins 上它失败了。

我的 WireMock 配置是

    @Rule
    public WireMockRule wireMockRule = new WireMockRule(wireMockConfig()
            .dynamicHttpsPort()
            .keystorePath(certsDir.resolve("server.jks").toString())
            .keystorePassword(MY_PASS)
            .keystoreType("JKS")
    );

我有 2 个 JUnit 类，我在其中创建了一个新的 WireMockRule，它们可以同时运行。在其中一门课程中，我有 4 个测试，而在另一门课程中，我有一个测试。 5 个测试全部失败。

Answer 1

找到解决方案here:

问题在于您没有设置任何一个 HTTP 端口，该端口将始终处于活动状态并默认为 8080（因此它们会发生冲突）。如果您将 dynamicPort() 添加到两个配置中，它应该可以修复它。

所以添加dynamicPort() 修复它：

    @Rule
    public WireMockRule wireMockRule = new WireMockRule(wireMockConfig()
            .dynamicPort()
            .dynamicHttpsPort()
            .keystorePath(certsDir.resolve("server.jks").toString())
            .keystorePassword(MY_PASS)
            .keystoreType("JKS")
    );
