angular - Angular 8.x e2e 测试不会运行

问题描述

使用 CLI 在 Angular 8.0.2 中为应用程序（减去路由）生成默认设置。

ng test工作，但ng e2e没有。该错误抱怨 Chrome。

我承认我仍在学习 Angular，但经过一番谷歌搜索后，我认为这个问题已经解决了，那么为什么会发生这种情况，我该如何解决呢？我的 chrome 浏览器版本（显示在 about chrome 中）是 Chrome 版本 74.0.3729.169

解决方案

Chromedriver 需要在本地安装特定版本的 chrome，因此请确保本地安装的 chrome 版本与驱动程序使用的版本相同。

由于某种原因，chrome 有时不会自动升级，但如果您转到帮助 -> 关于 Google Chrome，您可以看到您当前的版本并单击那里的按钮进行升级。
