在带有UI的Docker中执行Selenium测试

Question

我试着在码头机上运行selenium (Node )，但它写的是"TypeError: module.exports.browser.isElementPresent is not a function“。

注意：

• 我可以在本地机器上成功地运行同样的selenium测试。
• 我试着在docker上运行相同的测试，然后遇到了上面的错误。

root@6cd7ab2eb6f7:/usr/src# npm run kongaezv2
npm info it worked if it ends with ok
npm info using npm@4.1.2
npm info using node@v7.6.0
npm info lifecycle cerebro@0.0.1~prekongaezv2: cerebro@0.0.1
npm info lifecycle cerebro@0.0.1~kongaezv2: cerebro@0.0.1
