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

java jenkins junit wiremock

2022-09-04 19:47:05

我有一些Junit测试，其中我使用WireMock。在本地测试通过，但在 Jenkins 上，我得到一个错误java.lang.RuntimeException: java.net.BindException: Address already in use

在我设置的WireMock配置中（根据文档“在启动时随机对HTTPS端口进行签名”）及其在本地工作，但在Jenkins上它失败了。dynamicHttpsPort()

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，它们可以同时运行。在其中一个班级中，我有4个测试，在另一个班级中，我有一个测试。所有 5 个测试均失败。WireMockRule

答案 1

在此处找到解决方案：

问题是您没有设置HTTP端口，HTTP端口将始终处于活动状态，并且默认为8080（因此它们会发生冲突）。如果你将 dynamicPort（）添加到两个配置中，它应该修复它。

所以添加修复它：dynamicPort()

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