   # Use test fixture or provided file
   MEAL_PLAN_FILE="${ARGUMENTS:-tests/fixtures/test_meal_plan_weight_loss.json}"
   
   python -c "
   import json
   with open('${MEAL_PLAN_FILE}') as f:
       meal_plan = json.load(f)
   print(f'✅ Meal plan loaded: {len(meal_plan[\"days\"])} days')
   "
   

2. Generate PDF:

   import json
   
   with open('${MEAL_PLAN_FILE}') as f:

   pdf_path = generate_pdf(meal_plan, 'test_output.pdf')
   print(f'✅ PDF generated: {pdf_path}')
   "
   

3. Validate File:

   bashCopy

   # Check file exists and has content
   if [ -f "test_output.pdf" ]; then
       FILE_SIZE=$(stat -f%z "test_output.pdf" 2>/dev/null || stat -c%s "test_output.pdf")
       echo "✅ PDF file created: ${FILE_SIZE} bytes"
   
       # Expected size: 400-600 KB
       if [ $FILE_SIZE -lt 400000 ]; then
           echo "⚠️ File size too small (< 400KB)"
       elif [ $FILE_SIZE -gt 600000 ]; then
           echo "⚠️ File size too large (> 600KB)"
       else
           echo "✅ File size in expected range (400-600KB)"
       fi
   else
       echo "❌ PDF file not generated"
   fi
   

4. Validate PDF Structure:

   bashCopy

   python -c "
   from PyPDF2 import PdfReader
   
   reader = PdfReader('test_output.pdf')
   num_pages = len(reader.pages)
   
   print(f'📄 Total Pages: {num_pages}')
   
   # Expected: Cover + 30 days + 4 shopping lists = ~35 pages
   if num_pages < 30:
       print('❌ Too few pages (expected ~35)')
   elif num_pages > 50:
       print('⚠️ Too many pages (expected ~35)')
   else:
       print('✅ Page count looks good')
   
   # Check first page text
   first_page = reader.pages[0].extract_text()
   if 'Keto Meal Plan' in first_page:
       print('✅ Cover page detected')
   else:
       print('⚠️ Cover page may be missing')
   "
   

5. Visual Validation (open PDF):

   bashCopy

   # Open PDF for manual inspection
   if command -v open &> /dev/null; then
       open test_output.pdf
   elif command -v xdg-open &> /dev/null; then
       xdg-open test_output.pdf
   else
       echo "PDF saved to: $(pwd)/test_output.pdf"
