azure-devops - 在 Azure Pipelines 托管的 Linux 代理上运行 Cypress.io

Question

我正在尝试在 Azure Pipelines 的托管 Linux 池上运行 Cypress 测试。不幸的是，托管代理没有安装 Cypress 的所有依赖项。

运行记录的 apt-get 不起作用:

运行apt-get update需要很长时间(25分钟但仍未完成)。

欢迎提供有关如何让 Cypress 在托管代理上快速工作的任何线索。

注意:我尝试在 Windows 上运行，幸运的是，它有效，所以我没有完全被阻止。但要使用 Windows 代理，我现在有 2 个代理阶段，这会由于工件下载和 npm 安装开销而增加开销。

在运行 Cypress 之前，在 VSTS 代理阶段使用预先挂起的 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
