jest-preset-angular
Advanced tools
jest-preset-angular is a Jest preset configuration for Angular projects. It simplifies the setup and configuration of Jest for testing Angular applications, providing necessary configurations, transformers, and environment settings.
Setup and Configuration
This feature provides a preset configuration for Jest, making it easier to set up Jest in Angular projects. The code sample shows how to configure Jest to use jest-preset-angular in the Jest configuration file.
module.exports = { preset: 'jest-preset-angular', setupFilesAfterEnv: ['<rootDir>/setup-jest.ts'] };
Transformers
jest-preset-angular includes transformers to handle TypeScript and Angular templates. The code sample demonstrates how to configure Jest to use ts-jest for transforming TypeScript and HTML files.
module.exports = { transform: { '^.+\.(ts|html)$': 'ts-jest' } };
Global Mocks
jest-preset-angular provides global mocks for common Angular dependencies, such as Angular's testing utilities. The code sample shows how to import jest-preset-angular to include these global mocks in your tests.
import 'jest-preset-angular';
Karma is a test runner for JavaScript that works well with Angular. Unlike jest-preset-angular, which is a Jest preset, Karma is a standalone test runner that can be configured to work with various testing frameworks, including Jasmine and Mocha.
angular-testing-library is a set of utilities for testing Angular components. It focuses on testing user interactions and component behavior, similar to jest-preset-angular, but it is not a Jest preset and can be used with different test runners.
ng-mocks is a library for creating mocks of Angular components, directives, and services. It complements jest-preset-angular by providing additional mocking capabilities, but it is not a preset configuration for Jest.
