javascript - 阻止 Nightwatch/BrowserStack 集成运行的全局变量文件

Question

我正在尝试使用 browserstack-local 集成和本地运行器脚本在我机器上的 VM 上运行 Nightwatch 测试。当我没有在 browserstack.conf.js 中指定我的全局变量文件时，测试运行成功。

但是，当我在 conf.js 配置文件中链接我的全局变量文件时，我的测试抛出以下错误，指出我没有指定测试环境:

(注意:Top JSON 输出是我在 globals.js 文件中指定的自定义报告)

你是如何运行守夜人的？您是否包含配置文件？

node_modules/.bin/nightwatch --config browserstack.conf.js

答案原来是local.runner.js是一个脚本，应该这样运行:

node ./local.runner.js -c browserstack.conf.js
