New Features Added

1. Debugging Tools

   • Created API Test Page (api-test.html) for easy endpoint testing
   • Added test script (test-save-results.js) to verify data storage functionality
   • Created comprehensive debugging documentation (DEBUG.md)

2. Enhanced Endpoints

   • Added filtering and pagination to the /getResults endpoint

Testing Instructions

1. Session Data Testing

   • Use the API test page at http://localhost:3000/api-test.html
   • Create new test sessions with varying parameters
   • Verify sessions appear in both the test page and main application

2. Data Persistence Testing

   • Run the test script: node test-save-results.js
   • Verify data is properly stored and can be retrieved
   • Check that new users automatically get initialized in all data files

Conclusion

The application now handles session data more robustly, with improved error handling and fallback mechanisms when file access issues occur. The UI components have been updated to handle different data formats, ensuring a consistent user experience regardless of how the data is stored. New debugging tools make it easier to identify and fix issues in the future.
