vsts托管的代理docker容器(ubuntu)-无法运行守夜测试(连接到端口4444上的127.0.0.1时出错

Question

我试图在azure管道中运行硒测试，但遇到错误CICD管道使用VSTS托管代理并构建Ubuntu docker容器。

我的测试任务在Docker容器镜像构建后运行，并抛出以下错误。不确定我错过了什么。

在我的windows机器上可以找到测试结果。

如果需要任何进一步的信息，请告诉我

任何好的守夜码头项目都请扔到这里

我自己为这个问题找到了解决方案。对于那些曾经尝试过同样方法的人，

请确保Docker Ubuntu 中安装了正确的二进制文件

1. 软件包.json chrome devdependency正在将.exe二进制文件拉入Docker ubuntu(看起来是chrome驱动程序npm软件包的问题(

2. 确保稳定的linux chrome也安装在Docker Ubuntu 上

3. 首先尝试在本地Docker容器上设置项目，然后进入Docker容器进行调试(基本上是深入Docker容器并尝试在那里运行测试(。如果测试在那里正确运行，那么它们很可能应该在管道中正确运行

我计划很快写一个端到端的安装博客。一旦完成，我会在这里更新。
