How do I update angular.json to use Jest instead of Karma?
In angular.json, find the test section under your project's architect configuration and change the builder property from the default Karma builder to @angular-builders/jest:run. You can also provide additional Jest options in the options field of that same section.

How do I replace Karma and Jasmine with Jest in an Angular 18 project?
To replace Karma and Jasmine with Jest in Angular 18, first remove the existing packages by running npm remove karma karma-chrome-launcher karma-jasmine karma-jasmine-html-reporter, then install Jest and its builder with npm i -D jest @types/jest @angular-builders/jest, and finally update the test section in angular.json to point to the Jest builder.

What npm packages do I need to install to use Jest in Angular?
You need to install three packages as dev dependencies: jest for the test runner itself, @types/jest to get TypeScript type definitions for Jest APIs, and @angular-builders/jest which provides the Angular CLI builder that integrates Jest into the standard ng test workflow.

November 25, 2023 - To run tests in an Angular 17 project without installing it, you can use the npx command along with Jasmine and Karma. To accomplish this, simply execute the following command: npx ng test. Our goal is to use the Jest Builder, but before we do that, we must remove Karma and Jasmine from our project.

r/angular on Reddit: Jest in Angular.
December 17, 2024 -
Hello,
I want to hear from the community about Jest tests in Angular.
I have started using it because I listened to some opinions about is fast and "easy" to mock components, services, and so on.
Example:
- I have created a test on a mat toolbar to ensure that some menu items are shown or hidden depending if the user is an admin.
- PR: https://github.com/hseleiro/Organizer/pull/59
- Component: https://github.com/hseleiro/Organizer/blob/test/toolbar-component-jest-test/src/app/shared/components/toolbar.component.ts
- Unit Test: https://github.com/hseleiro/Organizer/blob/test/toolbar-component-jest-test/src/app/shared/components/toolbar.component.spec.ts

I like using Jest with Angular because it offers significantly faster test execution compared to Karma, thanks to its use of a virtual DOM (jsdom) and parallel test running. Jest is easy to set up, provides powerful mocking capabilities, and supports snapshot testing, which helps ensure the UI remains consistent. The clear error reporting and detailed logs make debugging much easier, and tools like @angular-builders/jest simplify its integration into Angular projects. Overall, it improves both test performance and developer experience, making it my preferred choice. The only downside I find with Jest is that when I run it on my computer, it makes it heat up quite a bit. But this can maybe be for all my index.ts files to analyse all dependecies. 😅
