我正在使用 jest 和 react 测试库来测试我的 react 应用程序。我想测试一个需要 ISR (nextJs getStaticProps) 来渲染的页面,所以我安装了 next-page-tester包裹。它正常呈现客户端呈现页面,但是当涉及到使用 ISR 呈现的页面时,发生了以下错误。 (我已经尝试在 jest.config.js 文件中添加 testEnvironment: 'jsdom' 和我的测试文件顶部的注释来配置 jsdom 环境)。
"test": "jest --env=jsdom",

The error below may be caused by using the wrong test environment, see https://jestjs.io/docs/configuration#testenvironment-string. Consider using the "jsdom" test environment.

我遇到了同样的问题,并且能够通过创建自定义 jsdom 环境来解决它。尝试此 URL 中的步骤
