puppeteer 出错后关闭页面

编程问答 2022-05-28

问题描述

在测试我的页面时，从依赖项中抛出错误。该错误并不严重，不会干扰我的应用程序。但是当使用 puppeteer 进行测试时，出现这个错误，他只是关闭了被测试的页面。我如何防止这种情况继续测试而忽略此错误？

示例：
这个错误被抛出到页面上，测试以它结束。

Error: TypeError: Cannot set property 'paddingLeft' of undefined

我的环境：

Puppeteer 版本：5.4.2
平台/操作系统版本：macOS 10.15.7
Node.js 版本：v12.16.1

解决方法

使用 jest-puppeteer 时，可以在 jest-puppeteer.config.js 中指定 exitOnPageError: false 参数。在这种情况下，如果页面出现错误，测试将无法完成。
