A preset of Jest configuration for Angular projects.

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

Configuration

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'],
};

or to your root package.json

{
  "jest": {
    "preset": "jest-preset-angular",
    "setupFilesAfterEnv": ["<rootDir>/setup-jest.ts"]
  }
}

Adjust your tsconfig.spec.json to be:

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