在本文中，我们将探索如何使用 Vitest 和 React Testing Library (RTL) 进行 React UI 的测试。我们首先需要关注一个辅助工具叫做 happy-dom，它能够在测试的运行环境（如 Node.js）中模拟实现 web 标准，解决因浏览器与测试运行环境不一致导致的测试问题。在开始测试前，需要在项目中安装 happy-dom ...

. We don’t have to do that for regular component tests that use React Testing Library utilities because those utilities manage the act call internally, but since we’re calling these state updater functions ourselves, we have to wrap things in act. Let’s do that for our useCounter hook....

Vitest 支持测试任何 JavaScript 和 TypeScript 代码。但是,为了测试 React 组件特定的功能(例如 React hooks),我们仍然需要为所需的 hook 创建一个包装器并模拟 hook 的执行。 为此,我们可以安装并使用React 测试库中的 Render hooks: yarnadd-D@testing-library/react-hooks ...
