Universal Plugin Jest

This is a plugin for the universal-scripts framework. It provides configuration for running tests with Jest in Universal-based projects.

Features

• Preconfigured setup for running tests with Jest.
• Supports unit and integration testing in React applications.
• Fully compatible with TypeScript and SWC for faster builds.
• Works with @testing-library/react and @testing-library/jest-dom for component testing (optional).

Installation

To install the plugin, run:

yarn add @gluedigital/universal-plugin-jest

If using npm

npm install @gluedigital/universal-plugin-jest

Now you can execute the tests with:

yarn test

If using npm

npm run test

If you need to test React components, you can install @testing-library/react and @testing-library/jest-dom for additional utilities:

yarn add -D @testing-library/react @testing-library/jest-dom

If using npm

npm install -D @testing-library/react @testing-library/jest-dom

Once installed, you can import them in your tests:

import { render, screen } from "@testing-library/react";
import "@testing-library/jest-dom";
import MyComponent from "./MyComponent";

test("renders the component correctly", () => {
  render(<MyComponent />);
  expect(screen.getByText("Hello, Jest!")).toBeInTheDocument();
});

Why Use This Plugin?

• Plug & Play: No need for complex Jest configurations—just install and start testing.
• Performance Optimized: Uses SWC for faster transformations.
• Flexible: Works with both JavaScript and TypeScript projects.
