+Data Enrichment Testing Suite
+
+This module provides comprehensive testing for the data_enrichment.py module.
+It validates all 14 API integrations, caching mechanisms, error handling,
+and batch processing capabilities.
+
+Usage:
+    python test_enrichment.py
+    
+    Or run specific test:
+    python -m unittest test_enrichment.TestDataEnrichmentManager.test_linkedin_enrichment
+
+Requirements:
+    - All RAPIDAPI_KEY_* environment variables must be set
+    - Internet connection required for API calls
+    - Test user: 'test_user' (creates test cache directory)
+
+Test Coverage:
+    - Initialization and configuration
+    - Individual API endpoint testing (14 APIs)
+    - Full contact enrichment workflow
+    - Batch processing capabilities
+    - Caching mechanisms and TTL
+    - Error handling and fallback logic
+    - Data privacy and per-user isolation
+    - Statistics and monitoring
