As a Computer Science student, I enjoy creating projects that help me apply software engineering concepts to real-world applications. One of my course projects was developing a Java-based Banking System that focused on object-oriented programming, software testing, and professional development practices.
The goal of this project was to design and implement a banking system while following a Test-Driven Development (TDD) approach. Instead of writing the code first, I created tests before implementation to guide the design of classes and methods and ensure the system worked correctly.
The Idea Behind the Project
The Banking System project was designed to simulate common banking operations while focusing on creating reliable and maintainable software. The project helped me understand how developers build applications by combining programming, testing, and collaboration.
Through this project, I worked on designing different components of a banking application and ensuring that each feature was properly tested before being added to the system.
Technologies and Tools Used
While developing this project, I worked with different technologies and tools used in software development.
Java – Used to design and implement the banking system using object-oriented programming concepts.
JUnit 5 – Used to create automated tests before implementation as part of the Test-Driven Development process.
PIT Mutation Testing – Used to evaluate the effectiveness of my test cases and improve code quality by identifying areas where additional testing was needed.
Gradle – Used for project management, building the application, and running automated tests.
GitLab – Used for version control, managing changes, and collaborating with team members.
What I Learned
Working on this project helped me understand the importance of writing reliable and maintainable software. I learned how TDD can improve the development process by encouraging developers to think about requirements and design before writing implementation code.
I also gained experience with testing tools such as JUnit 5 and PIT Mutation Testing. These tools helped me understand how developers ensure software quality and reduce errors before releasing an application.
Challenges and Problem Solving
One of the challenges I faced during this project was configuring development tools such as Gradle and PIT Mutation Testing. Resolving these issues required debugging, researching solutions, and collaborating with teammates.
This experience improved my problem-solving skills and helped me become more comfortable working with professional software development workflows.
