CHALLENGES

The client faced difficulties in ensuring the stability, scalability, and robustness of their MPOS system due to:

• Backend Server Access: Initially lacking access to the backend server made it difficult to verify transaction success.
• Workflow Identification: Identifying real-time workflows affecting end-user experiences and ensuring user comfort with the MPOS app posed challenges.
• NFC Feature Implementation: The absence of the NFC feature in the app added complexity to the testing process.

Solution Implemented:

Prakat conducted extensive functional and user experience testing, focusing on:

• Hybrid Testing Team: Prakat formed a hybrid team of testers for both User Acceptance Testing (UAT) and system testing to ensure comprehensive coverage.
• Load Testing: Simulated real-time behavior during peak hours by creating dummy loads from the front end, identifying reliability issues and application robustness under various transaction scenarios.
• End-to-End Workflow Verification: Conducted verification of transaction workflows from payment initiation to completion in the SDK portal for seamless functionality.
• Functional Workflow Checks: Verified functional workflows at each step to ensure a bug-free product and enhance user experience.

Technologies Used:

• Automated Testing Tools: To increase efficiency and coverage.
• User Feedback Mechanisms: For real-world insights.

Business Impact:

• Improved product reliability and user satisfaction.
• Enhanced user experience leading to increased adoption.

Results Achieved:

• Issue Resolution: UAT testing enabled the identification and resolution of end-user issues faced during real-time transactions, leading to enhanced customer satisfaction.
• Reliability Identification: Load testing uncovered reliability and robustness concerns under different transaction scenarios, allowing the client to address these proactively.

Conclusion:

Prakat’s comprehensive testing approach significantly enhanced the stability and user experience of the mobile POS system. By effectively addressing end-user issues and identifying potential reliability concerns, the client was able to launch a robust product that not only meets market demands but also improves customer satisfaction. This strategic partnership showcases the value of thorough User Acceptance Testing in achieving successful outcomes for mobile payment solutions.
