UI测试默认的执行器配置包括一个selenium-hub、一个chrome-node、一个firefox-node。
在默认配置下MeterSphereUI用例最大并行数为4，chrome-node最大会话数为6，既chrome-node最大支持6个并发。
在一个chrome-node中并行执行多个用例，即打开多个浏览器窗口时可能会导致页面加载速度变慢，需要给UI测试用例添加前后置等待时间。为了优化并行执行的效率，在服务器资源配置充足的情况下，可以在selenium-hub下部署4个chrome-node，同时使每个chrome-node最大支持一个会话。这样当UI用例并行时，每个chrome-node只执行一条用例，同时整体上也实现了并行，可以提升UI测试并行执行的效率。
以下配置为4个chrome-node，每个chrome-node最大会话数为1的yml配置：
