Description
Facing an issue while running the jest test in next.js

// jest.config.js
const nextJest = require('next/jest');
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
/** @type {import('jest').Config} */
const customJestConfig = {
// Add more setup options before each test is run
setupFilesAfterEnv: ['<rootDir>/jest.setup.js'],
// if using TypeScript with a baseUrl set to the root directory then you need the below for alias' to work
moduleDirectories: ['node_modules', '<rootDir>/', 'utils'],
moduleNameMapper: {
// Handle module aliases (This will be automatically configured for you soon)
...
'@uiw/react-md-editor': '<rootDir>/node_modules/@uiw/react-md-editor/lib/index.js',
'react-markdown': '<rootDir>/node_modules/react-markdown/react-markdown.min.js',
rehype: '<rootDir>/node_modules/rehype/index.js',
unified: '<rootDir>/node_modules/unified/index.js',
},
testEnvironment: 'jest-environment-jsdom',
preset: 'ts-jest',
transform: {
'^.+\\.(ts|tsx)?$': 'ts-jest',
'^.+\\.(js|jsx)$': 'babel-jest',
},
};
module.exports = async () => ({
...(await createJestConfig(customJestConfig)()),
transformIgnorePatterns: ['node_modules/(?!(monaco-editor)/)', '^.+\\.module\\.(css|sass|scss)$'],
});
module.exports = jestConfig;

Research direction
Start with jest.config.js and the referenced jest.setup.js, then reproduce the reported test failure in the Next.js application. The issue does not include the command or error details, so first identify the configuration error; done means the Jest tests run successfully with the intended setup.
