最后进行 expect 断言。 注意,上面的 renderHook 以及 act 方法是从 @testing-library/react 解构出来的,但是以前在旧版本中是需要安装 @testing-library/react-hooks 扩展库,然后从这个扩展库中解构 renderHook 和 act 方法,目前新版本已经将这两个方法整合到 @testing-library/react 这个扩展库里面了。 经过测试之...

I'm getting the React 18 createRoot warning when using renderHook. I've updated my app to react 18 already and have the latest testing library installed. Does anyone know the solution to this? import { renderHook } from "@testing-library/react-hooks"; test("should autoconnect", async ()...
React-Testing-Library入门旨在引导开发者高效地编写React组件测试。本文深入探讨了测试在React开发中的重要性,强调了自动化测试对于确保应用稳定性和质量的价值。引入的React-Testing-Library库以其简洁的API、专注于组件级别的测试以及对React库用法的原生支持,显著提高了测试的可读性和维护性。文章从基础概念、安装方法,...
如果我们通过creat-react-app创建项目会直接内置@testing-library/react,可以开箱即用,但是这里我们通过vite方式创建的react项目,vite构建的项目,默认是没有单测的,然后一步步完善test构建,这样做的好处呢就是我们自己熟悉配置构建流程,脱离cli脚手架工具,自由搭配; ...
