Setup
If you're running your tests in the browser bundled with webpack (or similar)
then DOM Testing Library should work out of the box for you. However, most
people using DOM Testing Library are using it with
the Jest testing framework with the testEnvironment set
to
jest-environment-jsdom
Using Without Jest
jsdom is a pure JavaScript implementation of
the DOM and browser APIs that runs in node. If you're not using Jest and you
would like to run your tests in Node, then you must install jsdom yourself.
There's also a package called
global-jsdom which can be used to
setup the global environment to simulate the browser APIs. Note that if you're
using Vitest you only need to configure
environment to jsdom to achieve
the same effect, you don't need global-jsdom.
First, install jsdom and global-jsdom.
- npm
- Yarn
npm install --save-dev jsdom global-jsdom
yarn add --dev jsdom global-jsdom
With mocha, the test command would look something like this:
mocha --require global-jsdom/register
