在GitLab CI作业上运行TestCafe Docker Image时出错。 尝试在BrowserStack上执行自动端到端测试

Question

我们正在尝试在gitlab CI作业触发的BrowserStack上运行testcafe端到端测试。 但是，我们看到一个错误：

Error: spawn /home/user/.browserstack/BrowserStackLocal ENOENT

我们正在关注选项1 - 使用TestCafe Docker Image https://devexpress.github.io/testcafe/documentation/continuous-integration/gitlab.html ，它为我们的.gitlab-ci.yml文件添加了一个端到端的测试工作。 我们创建了一个在.base_e2e作业中使用的e2e_dev作业库（见下文）

我们还使用了testcafe-browser-provider-browserstack npm依赖项 ，它允许我们的testcafe端到端测试在BrowserStack上执行，如https://devexpress.github.io/testcafe/documentation/using-testcafe/所述常见的概念/浏览器/浏览器的support.html＃浏览器，在云测试服务

这是gitlab CI作业错误的副本：

附加信息

当我们运行以下命令纱线即yarn test:e2e_pipeline执行端到端测试，并自动上传到BrowserStack的视频记录没有问题。

"scripts": {
    "test:e2e_all": "testcafe 'chrome,firefox' tests/e2e",
    "test:e2e_pipeline": "testcafe 'browserstack:Chrome@53.0:Windows 10' tests/e2e"
  },

我们的package.json有以下devDependencies

"devDependencies": {
    "testcafe": "^0.23.3",
    "testcafe-browser-provider-browserstack": "^1.7.0",
}

Answer 1

您不能将BrowserStack Local与官方TestCafe镜像一起使用。 TestCafe泊坞窗图像基于alpine:edge图像。 BrowserStack Local不支持Alpine Linux ，它的团队没有计划支持这个操作系统。 请在此主题https://github.com/browserstack/browserstack-local-nodejs/issues/32中查看有关它的讨论。 作为解决方法，您可以尝试基于BrowserStack Local支持的操作系统构建自己的docker镜像。
