目前在 Ubuntu EC2 上使用 Firefox 和 Chrome 节点运行 Selenium Grid。使用 TestNG 运行测试，通过 Firefox 节点运行的测试可以完美运行，但是使用 Chrome 节点时，我在导航到第二个 URL 后总是被拒绝连接。我发现令人困惑的是，当通过我的 Mac 在本地运行网格时，一切正常。

以下是 Chrome 测试的方式：

  • 获取登录页面 URL
  • 登录
  • 尝试获取新页面 URL
  • 拒绝连接

这个问题以前见过吗？对于类似的报告问题，我尝试了很多解决方案，但无济于事。我对 Selenium Grid 很陌生，所以我发现很难弄清楚发生了什么。

使用这些 chrome 参数修复：

    chromeOptions.addArguments("--safebrowsing-disable-auto-update ");
    chromeOptions.addArguments("--disable-background-networking");
    chromeOptions.addArguments("--no-proxy-server");
    chromeOptions.addArguments("--no-sandbox");
    chromeOptions.addArguments("--disable-extensions");
    chromeOptions.addArguments("--dns-prefetch-disable");
    chromeOptions.addArguments("--disable-gpu");
    chromeOptions.addArguments("--force-device-scale-factor=1");
    chromeOptions.setPageLoadStrategy(PageLoadStrategy.EAGER);
