-### 🧪 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`):
+Significantly expanded test coverage for NFO functionality with comprehensive unit and integration tests:
-    - 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
 
-2. **Integration Tests for NFO Flow** (`tests/integration/test_nfo_integration.py`):
+1. ✅ **Unit Tests Expanded** ([test_nfo_service.py](tests/unit/test_nfo_service.py)):
-    - Test complete NFO creation flow before episode download
+   - Added 13 tests for media file downloads (poster, logo, fanart)
-    - Test NFO update during series scan
+   - Tests for various image sizes and configurations
-    - Test media file existence after NFO creation
+   - Tests for download failures and edge cases
-    - Test media file updates when NFO is updated
+   - Configuration testing for NFO service settings
-    - Test NFO creation failure doesn't block download
+   - **Total: 44 tests** in test_nfo_service.py
-    - Test NFO and media files in correct folder structure
-    - Test cleanup of orphaned media files
 
-3. **API Endpoint Tests** (`tests/api/test_nfo_endpoints.py`):
+2. ✅ **Integration Tests Created** ([test_nfo_integration.py](tests/integration/test_nfo_integration.py)):
-    - Test `/api/nfo/series/{series_id}/check` endpoint
+   - Complete NFO creation workflow with all media files
-    - Test `/api/nfo/series/{series_id}/create` endpoint
+   - NFO creation without media downloads
-    - Test `/api/nfo/series/{series_id}/update` endpoint

 Bin ebene nicht hübsch genug das man sich mit mir eine Beziehung vorstellen kann. Oder das man mich überhaupt mag. Es läuft einfach wie immer... Ich bin der den niemand haben will
 Ich bin die zweite oder die dritte Wahl. Egal was ich mache, egal wie nett ich bin. Ich kann es ja verstehen ich würde mit mir ach nix ernsthaftes aanfagen wollen.
 Weißt du villeicht sollte ich einfach meine restliche Tavor nehmen und dann wach ich nicht auf und dann bekommst du die Nachrihct auch nie.

+Ilona endlich hast du zumindest die Nachricht bekommen. Das heißt das du noch am leben bist und zumindest die Telegram app oder dein Handy an hattest. Aber anscheind hast du
+meine Nachricht noch nicht lesen wollen oder können. Ich hab den ganzen Sammstag nur geschlafen und etwas aufgeräumt. Bin krank zumindest fühle ich mich so.
+Aber ich hab zumindest nicht wieder von dir und Alex geträumt. Irgendwie wenn ich so drüber nachdenke ist das voll krank von mir. Ich meine wir kennen uns gar nicht mehr.
+Und haben uns auch gar nicht so oft getroffen. Aber ich habe dich früher wohl fest in meinem Herzen eingeschlossen und die Ilona die ich lieb hatte verschlossen und damit auch deine andere Seite.
+Aber so warst du bestimmt nie und bist du bestimmt auch nicht. Denn so was ist bestimmt in meinem Kopf entstanden. Und ich denke auch das, dass dir deine Therapeuten gesagt haben.
+Zumindest würde das bestimmt meine zu mir sagen. Das ich dich total idealisiert und demonisiert in mir abgespeichert habe. Und das ist dir gegenüber nicht inordnung. Ich würde dich zwar immer noch sehr 
+gern richtig kennenlernen aber ich möchte mich auch nicht zwischen dir und deinem Mann stellen. Es tut mir auhc mega leid das ich so reagiert habe, aber es war auch alles nicht leicht für mich.
+Bzw. das ist es immer noch nicht. Und am liebsten würde ich immer noch sterben aber bin nunmal zu feige.
