npm install --save-dev jest eslint eslint-plugin-jest

Create an .eslintrc.js file with Jest-specific rules:

javascript
Copy
module.exports = {
  plugins: ['jest'],
  extends: ['eslint:recommended', 'plugin:jest/recommended'],
  env: {
    'jest/globals': true
  }
}

Essential ESLint Rules for Jest

Some key ESLint rules that significantly improve test quality:

javascript
Copy
{
  "rules": {
    "jest/no-disabled-tests": "warn",
    "jest/no-focused-tests": "error",
    "jest/no-identical-title": "error",
    "jest/prefer-to-have-length": "warn",
    "jest/valid-expect": "error"
  }
}
Pro Tips for Jest + ESLint
Use jest/consistent-test-it to enforce consistent test case naming across your codebase
Enable jest/require-top-level-describe to maintain organized test structure
Implement jest/no-large-snapshots to prevent unwieldy snapshot tests
Utilize jest/prefer-expect-assertions for async test reliability

Common Pitfalls to Avoid

Watch out for these common issues when using Jest with ESLint:

Running ESLint on test files without proper Jest environment configuration
Missing eslint-plugin-jest in your dev dependencies
Incorrectly configured file patterns in your ESLint configuration
Not excluding test files from certain general ESLint rules

Remember to run both Jest tests and ESLint checks in your CI pipeline to catch issues early. Consider using pre-commit hooks to enforce code quality before changes make it to your repository.
