Technology Stack

Backend Framework: SpringBoot

Spring Boot comes with built-in servers like Tomcat, Jetty, and Undertow, eliminating the need for additional setup. Its auto-configuration capability automatically adjusts based on dependencies, simplifying application configuration. It also provides out-of-the-box features such as Spring Data, Spring Security, and Spring Cloud, accelerating application development and integration. This makes it a widely adopted framework for building robust applications quickly.

Frontend Framework: Vue

Vue.js utilizes virtual DOM technology, enabling efficient DOM manipulation through memory-based data structures. It supports reactive data binding, virtual DOM rendering, and component-based architecture, delivering a flexible and maintainable development approach. When data changes, the UI updates automatically, allowing developers to focus on data handling rather than manual UI updates—highlighting Vue’s simplicity, flexibility, and efficiency.

Persistence Layer: MyBatisPlus

MyBatis-Plus enhances the MyBatis framework to streamline development. It supports multiple databases including MySQL, Oracle, SQL Server, and PostgreSQL. With rich APIs and annotations, it reduces manual SQL writing and includes a code generator that produces entity classes, Mapper interfaces, and XML mapping files. Additional features like pagination, dynamic queries, optimistic locking, and performance analysis further improve data operations. It helps developers build high-quality data access layers efficiently.

System Testing

Thorough testing is crucial for identifying system defects and ensuring quality. It validates whether the system meets customer expectations and corrects any issues found during testing. The ultimate goal is to ensure that the system functions correctly according to design specifications.

Purpose of System Testing

In the development cycle of a management system, testing is essential for quality assurance. It ensures the system's reliability and usability before deployement. The process involves simulating various usage scenarios to uncover defects and enhance user experience. A well-executed test process improves overall system quality and functionality.

Functional Testing

Functional tests are performed on system modules using methods like input validation, boundary value testing, and black-box testing techniques. Test cases are created and executed to validate each function. Below are sample test results for key modules:

Login Functionality Testing

User Management Testing

Testing Conclusion

This system uses black-box testing methodologies, simulating user interactions to verify functionality. Testing ensures that all processes operate as intended. It confirms the system meets functional and performance criteria, enhancing usability and reliability. All test scenarios align with user needs, ensuring that the final product is both effective and user-friendly.
