Step-by-Step Jest Configuration for Angular 18 | ngconf
August 27, 2024 - To use Jest in Angular, you can either set it up with the Angular Jest Runner to run tests with ng test, or configure Jest separately and run tests with the jest command. I prefer not using the Angular Jest Runner because I find it simpler to configure and use Jest on its own. npm install jest \ @types/jest \ @jest/globals \ jest-preset-angular \ --save-dev

r/angular on Reddit: Is Jest still going to be integrated officially with Angular?
March 3, 2025 -
I've been having a nightmare trying to reconfigure an old project's tests from Jasmine/Karma to Jest, because I have many coworkers advocating for it. But I'm surprised to see that while Karma has been deprecated for almost 2 years now, ng new and the refreshed Angular docs still only go over Karma, and make no mention of Jest or other testing frameworks at all https://angular.dev/guide/testing#other-test-frameworks.
This announcement https://blog.angular.dev/moving-angular-cli-to-jest-and-web-test-runner-ef85ef69ceca mentions @angular-devkit/build-angular:jest but I'm not sure if that's worth using - googling it actually points me to https://www.npmjs.com/package/@angular-builders/jest first but I'm not sure if this is something official.
jest-preset-angular also appears in lots of guides but it seems like every guide has a different way to set that up and I find its documentation kind of a nightmare of its own. Doesn't feel particularly futureproof.
Is Jest going to be a passing fad for Angular? Is there any news of deeper, documented integration anytime soon? Is Web Test Runner support at least close to being ready?

Jest relies on jsdom, which is missing polyfills for things that Chrome has implemented and are widely used by libraries. So anyone using Jest that has a dependency that uses TextEncoder has to decide if they want to write their own polyfill, switch to happydom, or remove the dependency, or my colleague’s favorite method - deleting affected .spec files.

Stick with jasmine until angular team implements proper jest support. They let you switch to jest but without testing coverage. Jest only has community support which is immature.
