Question

我正在尝试从 Jenkins 运行我的 protractor 程序，但由于Jenkins没有显示，我需要运行chrome in无头模式。由于 chrome 没有无头模式，我需要使用 {{3} 模拟显示 } 即可。

我遵循了一堆教程，但是当我运行量角器时，铬崩溃了。

以下是我所拥有的：

构建 - 执行Shell（在Jenkins工作中）

var r,words="We don't talk anymore\nWe don't talk anymore\nWe don't talk anymore\nLike we used to do\nWe don't love anymore\nWhat was all of it for?\nOh, we don't talk anymore\nLike we used to do\n\nI just heard you found the one you've been looking\nYou've been looking for"
words=words.split(/['\s]+/g);
r=[...words.reduce( (m, v) => m.set(v, ((m.get(v) || 0) + 1)), new Map() )].map(e=>[e[0],e[1]/words.length])
console.log(r)

这是我的输出：

#emulate display
echo "Starting xvfb on :99..."
Xvfb -ac :99 -screen 0 1280x1024x16 &
export DISPLAY=:99

echo "Checking that xvfb started ok..."
xdpyinfo -display :99 >/dev/null 2>&1 && echo "xvfb is using :99" || echo "xvfb is not using :99, it's free."

#now start my program
xvfb-run -a --server-args='-screen 0, 1024x768x16' protractor conf.js

我一直在尝试 + echo Starting xvfb on :99... Starting xvfb on :99... + export DISPLAY=:99 + echo Checking that xvfb started ok... Checking that xvfb started ok... + xdpyinfo -display :99 + Xvfb -ac :99 -screen 0 1280x1024x16 + echo xvfb is using :99 xvfb is using :99 [22:26:25] I/local - Starting selenium standalone server...

我建议使用Jenkins Xvfb Plugin。它的工作非常好，不必过多配置。

要设置作业，只需单击xvfb选项即可在作业开始时运行，并在作业结束时关闭xvfb。一旦设置完毕，就可以在没有xvfb内容的情况下执行Protractor命令：protractor conf.js。

如何使用Xvfb在Jenkins上使用chrome运行量角器？
