"""
test_pipeline.py -- End-to-End Pipeline Verification Script

WHAT:
    Sends a real POST request to the running FastAPI server at /analyze.
    Uses a real aircraft image and hardcoded engagement parameters.

WHY:
    Confirms the full pipeline runs without errors before any UI work begins.
    If this script returns clean JSON with all expected keys, the backend is ready.
    If it fails, we fix the backend here, not inside the HUD.

HOW TO USE:
    1. Start the FastAPI server in one terminal:
       uvicorn app.main:app --reload

    2. Run this script in a second terminal:
       python app/test_pipeline.py

EXPECTED OUTPUT:
    A JSON response containing:
    aircraft_name, missile_speed, missile_range, enemy_generation,
    maneuverability, no_aa_capability, eta_seconds, hit_probability, recommendation
