module.exports = {
 cacheDirectory: './custom-cache-directory',
 // Only cache test results for 24 hours
 cacheTimeout: 24 * 60 * 60 * 1000,
};
Maximizing Cache Benefits
Keep your tests atomic and independent
Avoid using non-deterministic data like timestamps
Clear cache when needed using jest --clearCache
Use --no-cache flag to bypass cache during troubleshooting

Remember that caching works best when your tests are predictable and well-structured. Random values or external dependencies can reduce cache effectiveness.

Advanced Caching Strategies

Consider implementing these strategies for optimal performance:

javascript
Copy
module.exports = {
  // Cache snapshot results
  snapshotSerializers: [],
  // Only test changed files
  onlyChanged: true,
};

By carefully managing your cache configuration, you can significantly reduce test execution time while maintaining reliability.
