The Problem

You want to write tests for your Preact components so that they avoid including implementation details, and are maintainable in the long run.

The Solution

The Preact Testing Library is a very lightweight solution for testing Preact components. It provides light utility functions on top of preact/test-utils, in a way that encourages better testing practices. Its primary guiding principle is:

The more your tests resemble the way your software is used, the more confidence they can give you.

Installation

This module is distributed via npm which is bundled with node and should be installed as one of your project's devDependencies:

npm install --save-dev @testing-library/preact

This library has peerDependencies listings for preact >= 10.

💡 You may also be interested in installing @testing-library/jest-dom so you can use the custom jest matchers.

📝 This library supports Preact X (10.x). It takes advantage of the act test utility in preact/test-utils to enable both Preact Hook and Class components to be easily tested.

📝 If you're looking for a solution for Preact 8.x then install preact-testing-library.
