University campus second-hand trading platform
More and more people are beginning to pay attention to second-hand transactions, which aim to reduce energy waste, high cost-effectiveness, etc.
An innovative and user-friendly second-hand item sharing platform designed specifically for college students. The platform was created to provide a more trustworthy and efficient environment for college students. Students can search, exchange, and list used goods such as textbooks, electronics, daily necessities, etc. based on their location.
UniChange will have a simple, user-friendly user interface that can be accessed on desktop, mobile devices, or as an app. For the safety of students and a good user experience, UniChange will provide user authentication through university email, product listings with images, smart search, a chat platform for buyers and sellers, and transaction status tracking.

Availability:
Student users can access the platform and browse/publish products at any time (24/7) and on any device (PC, mobile browser).
Extensibility:
It is more convenient to add new functional modules without modifying the core architecture, such as cross-school platform sharing.

Stability: No major crashes during the use of the platform.
Evaluate Availability；
Ensure that the system is accessible at any time when users need it, that the interface and pages respond normally, and that it has high availability.
Stress test: Simulate a large number of concurrent user accesses at the same time to test whether the system responds normally under high load.
Response time test: Test the loading time of core web pages under different network conditions.
Evaluate Extensibility：
Simulate the development of new functions: Let team members try to add a small module without modifying the existing logic.
Interface scalability test: Test whether the existing API interface is easy to expand parameters
Database expansion test: Add new tables and new fields to the database to verify that it does not affect existing queries or functions
Evaluate Security：
Authentication and authorization testing: Test the login interface multiple times to check if it is possible to bypass the security authentication system.
Encryption testing: Verify whether sensitive data (such as passwords) are stored encrypted.
