 1. ✅ **TMDB API Integration**: Added `get_tv_show_content_ratings()` method to TMDBClient
 2. ✅ **Data Model**: Added optional `fsk` field to `TVShowNFO` model
 3. ✅ **FSK Extraction**: Implemented `_extract_fsk_rating()` method in NFOService with comprehensive mapping:
-   - Maps TMDB German ratings (0, 6, 12, 16, 18) to FSK format
-   - Handles already formatted FSK strings
-   - Supports partial matches (e.g., "Ab 16 Jahren" → "FSK 16")

-### 🧪 Priority: Comprehensive NFO and Image Download Tests
+### 🧪 Priority: Comprehensive NFO and Image Download Tests ✅ COMPLETED
 
 **Task: Add Comprehensive Tests for NFO Creation and Media Downloads**
 
-Expand test coverage for NFO creation, updates, and media file (poster/logo/fanart) downloads.
+**Status: COMPLETED** ✅
 
-**Requirements:**
+**Implementation Summary:**
 
-1. **Unit Tests for NFO Service** (`tests/unit/test_nfo_service.py`):
-    - Test auto-create NFO before download with all settings combinations
-    - Test NFO update on scan (enabled/disabled)
-    - Test poster download (enabled/disabled, various sizes)
-    - Test logo download (enabled/disabled, English/local languages)
-    - Test fanart download (enabled/disabled, various sizes)
-    - Test concurrent media downloads
-    - Test media download failures and retries
-    - Test NFO creation without media downloads
-    - Test image size configurations (original, w780, w500, w342)
-    - Mock TMDB API responses for all scenarios
+Significantly expanded test coverage for NFO functionality with comprehensive unit and integration tests:
 
-2. **Integration Tests for NFO Flow** (`tests/integration/test_nfo_integration.py`):
-    - Test complete NFO creation flow before episode download
-    - Test NFO update during series scan
-    - Test media file existence after NFO creation
-    - Test media file updates when NFO is updated
-    - Test NFO creation failure doesn't block download
