Key Technologies

Java provides a robust, object-oriented environment with strong typing and automatic memory management. Encapsulation, inheritance, and polymorphism enable modular and reusable code.

Spring Boot minimizes configuration overhead by auto-configuring components and embedding the server. It integrates a wide ecosystem of libraries while avoiding dependency conflicts.

MySQL is a high-performance relational database offering data integrity, fast queries, and flexible access control. It is well suited for web applications requiring shared, low-redundancy data storage.

Testing Approach

Testing was conducted both on local servers and through structured verification methods. White-box testing examined internal logic and path coverage, while black-box testing validated functional requirements from an end-user perspective. The primary goal was to uncover defects before deployment.

Tests followed principles such as tracing back to user needs, beginning with smaller components before integration, and focusing on high-risk modules (Pareto principle). Test cases were designed to cover major functional areas, including forum interactions, file handling, and role-based access.
