Hi @vivid vigil. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Based on the provided extracts, there's no specific information about setting up Jest for a Next.js application with Redux. However, I can guide you on how to set up Jest for a Next.js application.
Firstly, since the release of Next.js 12, Next.js now has built-in configuration for Jest. To set up Jest, install jest and the following packages as dev dependencies:
npm install -D jest jest-environment-jsdom @testing-library/react @testing-library/jest-dom
# or
yarn add -D jest jest-environment-jsdom @testing-library/react @testing-library/jest-dom
# or
pnpm install -D jest jest-environment-jsdom @testing-library/react @testing-library/jest-dom
Then, generate a basic Jest configuration file by running the following command:
npm init jest@latest
# or
yarn create jest@latest
# or
pnpm create jest@latest
This will take you through a series of prompts to setup Jest for your project, including automatically creating a jest.config.ts|js file.
Update your config file to use next/jest. This transformer has all the necessary configuration options for Jest to work with Next.js. Here's an example of how your jest.config.ts file might look:
import type { Config } from 'jest'
import nextJest from 'next/jest.js'
const createJestConfig = nextJest({
// Provide the path to your Next.js app to load next.config.js and .env files in your test environment
dir: './',
})
// Add any custom config to be passed to Jest
const config: Config = {
coverageProvider: 'v8',
testEnvironment: 'jsdom',
// Add more setup options before each test is run
// setupFilesAfterEnv: ['<rootDir>/jest.setup.ts'],
}
// createJestConfig is exported this way to ensure that next/jest can load the Next.js config which is async
export default createJestConfig(config)
Under the hood, next/jest is automatically configuring Jest for you, including setting up transform using the Next.js Compiler, auto mocking stylesheets (.css, .module.css, and their scss variants), image imports and next/font.
For more detailed information, please refer to the Next.js Documentation (https://nextjs.org/docs/app/building-your-application/testing/jest#manual-setup).

Let me check the knowledge base for you. One moment! :books:
I'm sorry, but the provided extracts do not contain specific information on how to test react-slick with Jest. However, you can generally test React components using Jest and a testing library such as @testing-library/react.
