The Nx Plugin for Jest contains executors and generators allowing your workspace to use the powerful Jest testing capabilities.
@nx/jest is a package that integrates Jest testing framework with Nx, a set of extensible dev tools for monorepos. It allows you to run and manage Jest tests efficiently within an Nx workspace.
Running Jest Tests
This configuration allows you to run Jest tests for multiple projects within an Nx workspace. The 'projects' array specifies the paths to the projects you want to include.
module.exports = {
projects: ['<rootDir>/apps/my-app', '<rootDir>/libs/my-lib'],
};
Custom Jest Configuration
This sample shows how to create a custom Jest configuration for a specific project within an Nx workspace. It includes settings for transforming files, module file extensions, and coverage directory.
module.exports = {
displayName: 'my-app',
preset: '../../jest.preset.js',
transform: {
'^.+\\.[tj]sx?$': 'babel-jest',
},
moduleFileExtensions: ['ts', 'tsx', 'js', 'jsx'],
coverageDirectory: '../../coverage/apps/my-app',
};
Running Tests with Nx CLI
You can run tests for a specific project using the Nx CLI. This command runs the tests for the 'my-app' project.
nx test my-app
Jest is a delightful JavaScript testing framework with a focus on simplicity. It works out of the box for most JavaScript projects. While @nx/jest integrates Jest with Nx, Jest itself is a standalone testing framework.
Karma is a test runner developed by the AngularJS team. It allows you to run tests in multiple real browsers. Unlike @nx/jest, which is focused on Jest integration, Karma is more about running tests in different environments.
Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser. It makes asynchronous testing simple. Mocha is more flexible and less opinionated compared to Jest, which is more integrated and comes with more built-in features.
Nx is a build system, optimized for monorepos, with plugins for popular frameworks and tools and advanced CI capabilities including caching and distribution.
This package is a Jest plugin for Nx.
