无法使用Chrome无头和Xvfb运行量角器测试

Question

我一直在搜索并尝试不同的解决方案已有近一周的时间，但仍然找不到答案。

首先，我的环境是：Server Debian 8（无GUI），Protractor 4.0.9，Selenium Server 2.53.1（使用webdriver-manager启动），Chromedriver 2.24.417424，Chrome 54.0.2840.100，Firefox 43.0，Xvfb

我正在尝试使用无头Chrome浏览器执行测试，但是Chrome无法启动。 请注意，我能够使用Firefox完全免费运行测试。 这是我尝试使用Chrome运行测试时的输出：

总是一样的。 我可以使用Xvfb正常运行Chrome和Firefox，并且手动启动chromedriver可以正常运行。

这是我用来启动Xvfb的命令：

Xvfb -ac :99 -screen 0 1280x1024x16 &
export DISPLAY=:99

手动启动chromedriver时的输出：

Starting ChromeDriver 2.24.417424 (c5c5ea873213ee72e3d0929b47482681555340c3) on port 9515

希望你们能帮助我。

您需要使用命令xvbf-run protractor configuration.js启动量角器过程。
