Testing a fintech payment platform

In the fintech sector, a company developed a mobile payment platform that enables banking transactions via a contact list - protected by PIN and with a focus on protecting sensitive data.

The challenge was to provide a stable and functional multi-platform solution (iOS, Android, web business platform, back office system) that ensures seamless synchronization across various devices and operating systems without compromising on performance or data protection.

Test focus: Systematic approach for high quality

To ensure security, functionality and usability, our testing team integrated itself into the development process at an early stage. Structured tests were agreed and carried out during the sprint phases.

The focus was on

• Test analysis: identification of critical areas.
• Manual testing: checking for user-friendliness and functionality.
• API tests: ensuring smooth data flows.
• Test automation: increasing efficiency, especially for regression tests.

Best-of-breed tools such as Jira, Xray, Selenium, Appium and Browserstack were used to enable high test coverage and speed up error detection.

Particular attention was paid to security and performance testing to ensure a robust and scalable solution. Testing was carried out on various end devices, including mobile devices with different operating systems, to ensure compatibility.

Result: Stability and user-friendliness through quality assurance

This systematic testing approach ensured that the developed software was stable and error-free.

• The solution is robust, scalable and user-friendly.
• Early identification of potential security risks protects sensitive data.
• The test strategy achieved good coverage of the requirements and relevant errors were identified and rectified at an early stage.
• Close cooperation between development and quality assurance ensured that customer requirements were met.

Lessons learned:

• Early integration of testing pays off: Software testing should not only take place at the end, but throughout the entire development process.
• Systematic test strategy: A well thought-out test concept is the key to success, especially in the fintech industry, where security and functionality are essential.
• Test automation as an enabler: Automated tests increase efficiency and enable the early detection of regressions.
• Collaboration: Close collaboration between developers and testers ensures customer-friendly and efficient software.

Our approach underscores how structured quality assurance contributes significantly to the delivery of reliable software, allowing you to benefit from more stable applications, lower maintenance costs and a better user experience in the long term.
