在VSTS托管Linux上运行Cypress.io

Question

我正在尝试在托管Linux池上运行针对Visual Studio Team Services的赛普拉斯测试.不幸的是,托管代理没有安装赛普拉斯的所有依赖项.

运行文档apt-get不起作用:

跑步apt-get update需要永远(25分钟,但仍未完成).

有关如何让赛普拉斯在托管代理上快速工作的任何线索都是受欢迎的.

注意:我尝试在Windows上运行,幸运的是,所以我没有被完全阻止.但是要使用Windows代理,我现在有2个代理阶段,这会因为人工制品下载和npm安装开销而增加开销.

在运行赛普拉斯之前,在VSTS代理阶段使用预先安装的Shell(Bash)任务解决了该问题:

apt-get -qq -y update
apt-get -qq -y install xvfb libgtk2.0-0 libnotify-dev libgconf-2-4 libnss3 libxss1 libasound2
