Ticket

• TEST010 - Recommendation Personalisation Testing

Description

Summary
Completed testing of the recommendation system's personalisation capabilities based on user profiles (allergies, dietary preferences, and nutrition guardrail level).

Testing Scope

• Created 3 test profiles with different conditions
• Tested key scenarios: allergy warnings, dietary preference respect, health guardrail impact, and alternative product suggestions
• Performed testing primarily on Web version (Expo) due to device connection issues

Key Findings

• Allergy detection and warnings work reasonably well
• Dietary preferences (Vegan / Vegetarian) are not consistently respected in recommendations
• Nutrition Guardrail Level has limited to no observable impact
• Alternative suggestions are generally healthier but often not strongly relevant to the scanned product

Files Added/Modified

• mobile-app/testing/TEST010_Recommendation_Personalisation_Testing.md
• mobile-app/testing/TEST010_Recommendation_Personalisation_Testing.pdf

Note: Owing to persistent Expo connection issues with physical device, testing was conducted only on Web version and real device testing shall be done later if necessary
