print(f'Prediction: {result}')
"

3. Slot Optimization Test

python -c "
from app.services.slot_optimizer import SlotOptimizer
from datetime import date, timedelta
optimizer = SlotOptimizer()
slots = optimizer.get_available_slots(1, date.today() + timedelta(days=1))
print(f'Found {len(slots)} slots')
print(f'Top slot: {slots[0] if slots else None}')
"

4. Priority Scoring Test

python -c "
from app.services.priority_scorer import PriorityScorer
from app.models.models import Patient
scorer = PriorityScorer()
# Test emergency patient
class TestPatient:
    age = 75
    is_emergency = True
score = scorer.calculate_priority(TestPatient(), 'chest pain', True)
print(f'Priority Score: {score}')  # Should be high (70+)
"

5. Web Application Test

# Start the development server
python run.py

# Then visit:
# http://localhost:5000/patient/book - Patient booking
# http://localhost:5000/admin/appointments - Admin panel
# http://localhost:5000/patient/check-status - Status checking
