Jest Preset Angular

A preset of Jest configuration for Angular projects.

Build Status NPM Version GitHub license

Our online documentation is available at

This is a part of the article: Testing Angular faster with Jest.

Getting Started

These instructions will get you setup to use jest-preset-angular in your project. For more detailed documentation, please check online documentation.

Install using yarn:

yarn add -D jest jest-preset-angular @types/jest

Or npm:

npm install -D jest jest-preset-angular @types/jest


In your project root, create setup-jest.ts file with following contents:

import 'jest-preset-angular/setup-jest';

Add the following section:

  • to your root jest.config.js
// jest.config.js
module.exports = {
  preset: 'jest-preset-angular',
  setupFilesAfterEnv: ['<rootDir>/setup-jest.ts'],
  globalSetup: 'jest-preset-angular/global-setup',
  • or to your root package.json
  "jest": {
    "preset": "jest-preset-angular",
    "setupFilesAfterEnv": ["<rootDir>/setup-jest.ts"],
    "globalSetup": "jest-preset-angular/global-setup"

Adjust your tsconfig.spec.json to be:

  "extends": "./tsconfig.json",
  "compilerOptions": {
    "outDir": "./out-tsc/spec",
    "module": "CommonJs",
    "types": ["jest"]
  "include": ["src/**/*.spec.ts", "src/**/*.d.ts"]


Angular doesn't support native async/await in testing with target higher than ES2016, see angular/components#21632 (comment)
