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
.
