Sap 使用Project Piper进行自动测试

我们目前正在为基于的SCP CF环境设置CI/CD管道。经过大量的尝试和错误，我们已经完成了重要的过程，但是我们仍然无法运行我们的业力测试

我们知道我们需要使用，但是我们无法启动/连接到sidecar容器中的Chrome

要在Jenkins上运行

karmaExecuteTests

步骤，需要安装Docker deamon。我想是这样的

在Docker sidecar模式中，容器可以使用它们的容器名称相互交谈（

karma

&

selenium

）。因此，对于浏览器（

config.customLaunchers.chromeSel.config.hostname

），您可以将主机名正确设置为

selenium

，但您还需要将

config.hostname

设置为

karma
您不需要声明要在karma配置中使用的
karma-
前缀模块，它们默认情况下是导入的。此外，您还应该考虑将<代码>安装命令中提到的模块添加到代码< >包中。JSON<代码>文件，并退回到默认的代码>安装命令< /代码>。谢谢有关删除业力插件的提示。安装的模块已经是package.json文件的一部分，因此我可以用
installCommand:“npm config set@sap:registry”替换
installCommand
https://npm.sap.com &&npm安装--quiet“
另一句话：要有一致的开发设置，您应该在项目存储库中的
.npmrc
文件中定义范围注册表
@sap…registry
。这样，您也可以省略
nom config set
命令。谢谢，克里斯托弗！这是缺少的一部分，它现在适用于JS代码。您知道如何在不定义新的docker容器或使用这些几乎没有维护的docker容器（包括Chrome和nodejs）的情况下测试nodejs代码吗。？Selenium容器不包括nodejs，并且没有用于中sidecarContainer的
安装命令。。。
