全局变量文件阻止Nightwatch / BrowserStack集成运行

问题描述 投票：2回答：1

我正在尝试使用browserstack-local集成和本地运行程序脚本对我机器上的VM运行我的Nightwatch测试。当我没有在browserstack.conf.js中指定我的全局变量文件时，测试成功运行。

但是，当我在conf.js配置文件中链接我的全局变量文件时，我的测试会抛出以下错误，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）

你是怎么跑夜班的？你是否包含配置文件？

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

答案结果是local.runner.js是一个脚本，应该运行如下：

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