As part of the changes for React 18, it has been decided that the renderHook API provided by this library will instead be included as official additions to both react-testing-library (PR) and react-native-testing-library (PR) with the intention being to provide a more cohesive and consistent...
This PR migrates test suites that userenderHookfrom the library@testing-library/react-hooksto adopt the equivalent and replacement ofrenderHookfrom the export that is now available from @testing-library/react. This work is required for the planned migration to react18. Context In this PR, usages ...
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 ()...

@testing-library[1]是一系列建立在DOM Testing Library[2](@testing-library/dom)基础上的包的集合。用来测试 UI 组件,不鼓励测试实现细节(比如组件内部状态、方法甚至生命周期),而是鼓励从用户使用的角度进行测试。 作为初级教程,篇幅有效,本文只讨论@testing-library/react[3]的使用,有其他需求的同学,可以查阅对应...
测试自定义 React hooks 现在,让我们看一个自定义hook的例子以及如何使用React Testing Library进行测试。我们已将计数逻辑提取到名为useCounter的自定义React hook中。 该hook接受一个初始计数作为可选prop,并返回一个具有当前计数值和增加函数的对象。以下是useCounter hook的代码: ...
Let's change the useCounter example from the Basic Hooks section to get a step value from context and build a CounterStepProvider that allows us to set the value: import React, { useState, useContext, useCallback } from 'react'const CounterStepContext = React.createContext(1)export...
Importing@testing-library/react-hooks/dont-cleanup-after-each.jsin test setup files will disable the auto-cleanup feature. For example, inJestthis can be added to yourJest config: module.exports={ setupFilesAfterEnv:[ '@testing-library/react-hooks/dont-cleanup-after-each.js' ...

As you begin to make use of React hooks in your applications, you’ll want to be certain the code you write is nothing short of solid. There’s nothing like shipping buggy code. One way to be certain your code is bug-free is to write tests. And testing React hooks is not much ...
