A modern jsdom test environment for Jest
npm install @bufbuild/jest-environment-jsdomAn extension of jest-environment-jsdom
with support for the Encoding API.
When using the test framework Jest for a web application, you will likely use the "jsdom" test
environment to make the DOM available in tests. But if your code or one of your dependencies relies on the encoding API,
you will see the following error when running tests:
``
ReferenceError: TextEncoder is not defined
This package adds the Node.js built-in classes TextEncoder and TextDecoder to the jsdom test environment to work
around the problem. If you can spare the time, consider helping out with the
upstream issue in the jsdom project.
Install the package (note that jest-environment-jsdom is still required as a peer dependency):
`bash`
npm install --save-dev jest-environment-jsdom @bufbuild/jest-environment-jsdom
Update the testEnvironment property of your Jest config like so:
`diff
import type { Config } from 'jest';
const config: Config = {
- testEnvironment: 'jsdom',
+ testEnvironment: '@bufbuild/jest-environment-jsdom',
...
};
