在Jenkins的WireMock在Jenkins - BindException：地址已经在使用

Question

我有一些Junit测试，我使用WireMock。本地测试通过，但詹金斯我得到的 java.lang.RuntimeException: java.net.BindException: Address already in use

错误在我设置dynamicHttpsPort()（其中根据文档“随机asssign在启动 HTTPS端口”）和WireMock配置其本地工作，但詹金斯失败了。

我WireMock配置

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

我有我创建一个新的WireMockRule 2个JUnit类，它们可以同时运行。在其中一个班级中，我有4个考试，而另一个班级中有一个考试。所有5个测试失败。

而且全堆栈跟踪：

Answer 1

找到了解决办法here：

的问题是，你没有设置在任一HTTP端口，这将始终是积极和默认为8080（因此它们发生冲突）。如果将dynamicPort（）添加到两个配置中，它应该修复它。

因此增加dynamicPort()固定它：

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