•
User Experience (UX): In the context of this project, user experience refers to
the overall impression and interaction customers have with the application. A
positive UX is crucial for the success of the rewards program because it directly
affects customer satisfaction, engagement, and retention. A well-designed and
intuitive interface, coupled with seamless navigation and efficient functionality,
can significantly enhance the user experience. The application should be
visually appealing, easy to use, and responsive across different devices. By
ensuring a positive UX, the bank can encourage customers to actively
participate in the rewards program, explore its features, and have a pleasant
overall experience, thereby strengthening their loyalty and engagement.
•
Data Analysis: Data analysis plays a vital role in understanding customer
behavior and preferences, which is crucial for designing and implementing an
effective rewards program. By analyzing transaction data and user behavior
patterns, the application can gain insights into customers' preferences, spending
habits, and engagement levels. These insights enable the bank to personalize the
rewards program and provide tailored recommendations to individual
13 | P a g e
customers. For example, analyzing a customer's transaction history can help
identify their preferred categories of spending, allowing the application to offer
targeted rewards and recommendations related to those categories.
Additionally, data analysis can help identify trends, patterns, and anomalies that
can inform decision-making processes, such as identifying popular reward
options or detecting fraudulent activities. By leveraging data analysis
techniques, the bank can optimize the rewards program, make data-driven
decisions, and deliver a more personalized and engaging experience for its

more challenging for banks to differentiate themselves and retain their customers. A
well-designed and effective rewards program can be a powerful tool in this regard, as it
provides customers with an added incentive to stay with the bank and use its services.
However, many existing rewards programs are complex and confusing, with low
redemption rates and limited value for customers. This can result in a lack of
engagement and loyalty from customers, and a decreased return on investment for the
bank. Therefore, the motivation for this project is to design a rewards program that is
simple, transparent, and rewarding, and that provides tangible benefits to customers.
To make the application more engaging and playful, gamification has been
incorporated into the design. By including elements such as leaderboards, badges, and
progress bars, users can feel a sense of achievement and satisfaction as they use the
14 | P a g e
application and earn rewards. The gamification features also help to create a sense of
community and competition among users, which can further increase engagement and

In addition to their core features, Mockito and JUnit also offer a range of advanced features
for more complex testing scenarios. For example, Mockito allows developers to verify
interactions between multiple objects and to stub methods with complex behavior. JUnit
supports parameterized tests, which allow developers to run the same test with multiple
inputs, and test suites, which allow multiple test cases to be run together. Overall, Mockito
and JUnit are powerful tools that can help developers write reliable, maintainable code with
confidence.
2.3. INTRODUCTION TO REACTJS
ReactJS, also known simply as React, is an open-source JavaScript library for building user
interfaces. Developed and maintained by Facebook, React has become one of the most
popular web development tools in recent years. React is designed to be fast, efficient, and
scalable, making it an ideal choice for enterprise-level development projects.
21 | P a g e
One of the key features of React is its use of a virtual DOM (Document Object Model). The
virtual DOM is a lightweight, in-memory representation of the actual DOM. By
manipulating the virtual DOM instead of directly updating the actual DOM, React can
minimize the number of updates needed and significantly improve performance.
Another important feature of React is its component-based architecture. React components
are self-contained, reusable building blocks that can be combined to create complex user
interfaces. This modular approach makes it easier to develop and maintain large-scale
applications, as each component can be updated and tested independently.
React also includes a powerful set of developer tools, including the React Developer Tools
browser extension, which allows developers to inspect and manipulate the virtual DOM,
view component hierarchies, and debug their code. React's comprehensive documentation
and active community also make it easy for developers to get started and solve problems
quickly.
For enterprise-level development, React also offers several features to support large-scale
applications. For example, React supports server-side rendering, which can improve the
performance and SEO of web applications. React also integrates well with other
technologies and frameworks, such as Redux for managing application state, and supports
internationalization and accessibility features.
Overall, React's speed, scalability, and modular architecture make it a popular choice for
building large-scale, enterprise-level web applications. Its comprehensive documentation,
active community, and developer tools also make it a developer-friendly choice for both
