Protractor 通过selenium网格在多个节点（操作系统平台）中运行量角器测试脚本
我目前正在尝试使用selenium网格运行量角器测试脚本。我的目标是将量角器测试脚本分发到在不同风格的操作系统下运行的多个节点。它还应该并行运行测试脚本的不同部分，以节省执行时间。当我使用webdriver manager将测试分发到多个实例时，当前的设置是有效的，但webdriver manager只允许我使用一个节点。我知道使用selenium grid可以解决此问题，但在测试控制台中我遇到以下错误：Protractor 通过selenium网格在多个节点（操作系统平台）中运行量角器测试脚本,protractor,selenium-grid2,Protractor,Selenium Grid2,我目前正在尝试使用selenium网格运行量角器测试脚本。我的目标是将量角器测试脚本分发到在不同风格的操作系统下运行的多个节点。它还应该并行运行测试脚本的不同部分，以节省执行时间。当我使用webdriver manager将测试分发到多个实例时，当前的设置是有效的，但webdriver manager只允许我使用一个节点。我知道使用selenium grid可以解决此问题，但在测试控制台中我遇到以下错误： node_modules/selenium-webdriver/error.js:26
