Selenium 隐藏Xvfb终端日志

每次我使用Xvfb在headless firefox中执行测试时，都会得到大量日志。这些日志显示不同的参数及其值

我想知道我是否能以某种方式禁用这些日志，我在谷歌上搜索了一下，但找不到任何有用的东西

将显示以下日志，我想禁用这些日志

这里也有同样的问题。没有找到一个干净的解决方案来禁用它们，所以我在Jenkins中包含了一个预构建任务，在运行自动测试之前清理这些日志文件。由于Jenkins定期启动我的自动化测试，日志经常被清理。这样我就不会冒磁盘已满的风险。

有许多方法可以解决此问题。我首先建议在运行代码的另一个终端中初始化Xvfb。Xvfb日志消息将转储到它运行的终端中

另一个解决方案是使用包装器。例如，如果您使用python编写代码，您可以尝试https://github.com/cgoldberg/xvfbwrapper

如果您将日志输出从Xvfb重新定向到/dev/null，那么这些详细消息就会消失

在我的例子中，我在Jenkins中使用Xvfb插件，并在CentOS机器上使用Firefox运行Selenium测试。收到了同样冗长的信息

我通过取消选中其中一个用于记录Xvfb日志输出的框来解决这个问题，或者

您也可以在$or提示符下执行此操作：

/usr/bin/Xvfb:99-ac-屏幕0 1600x1200x16 2>/dev/null 1>&2&
