我试图让服务器安装无头镀铬，硒webdriver和量角器，以便自动化测试。
我使用这些说明设置了我的环境：
# JDK 8
sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update && sudo apt-get install openjdk-8-jdk
# Node JS
curl -sL https://deb.nodesource.com/setup_6.x | sudo bash -
sudo apt-get install -y nodejs
# NPM modules
sudo npm install protractor -g
sudo npm install chromedriver -g
# Google Chrome
echo "deb http://dl.google.com/linux/chrome/deb/ stable main" | sudo tee -a /etc/apt/sources.list
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
sudo apt-get update
sudo apt-get -y install libxpm4 libxrender1 libgtk2.0-0 libnss3 libgconf-2-4
sudo apt-get -y install google-chrome-stable
sudo apt-get -y install xvfb gtk2-engines-pixbuf
sudo apt-get -y install xfonts-cyrillic xfonts-100dpi xfonts-75dpi xfonts-base xfonts-scalable
sudo apt-get -y install imagemagick x11-apps
Xvfb -ac :99 -screen 0 1280x1024x16 &
disown $1
export DISPLAY=:99
问题在于，当我第一次运行量角器测试时，它运行良好且测试运行完美。但是当有服务器重启或其他什么时，我似乎无法再次运行它。现在这是因为当我做webdriver-manager start时，这是我的输出：

如您所见，它显示的是边缘浏览器而不是chrome。为什么它会被切换回来？有没有办法永久存储它，还是我应该做一些其他命令来指定我需要使用chrome？
答案 0 :(得分：3)
我看到IE，Edge，Safari和Opera被跳过（这是预料之中的）。启动WebDriver管理器后，转到http://localhost:4444/grid/console并检查已注册的内容。
查看量角器的Setting Up the Browser。
