Business Challenge

Tietoevry Banking initiated a long-term strategic project to modernize one of its major software products – a core banking platform that is offered as a SaaS solution to customers. The key goal was to enhance the platform’s performance and elevate the customer experience by replacing the legacy mainframe-based architecture with microservices.

The new platform architecture had to incorporate a broad spectrum of new REST and SOAP services, batch processing, and messaging queues (MQs), which had to be thoroughly tested before deployment. After re-examining its QA maturity, Tietoevry Banking discovered a substantial misalignment between the testing and development activities, as well as gaps in QA processes, which caused a range of pressing issues:

System errors across multiple services and hampered integrations between the platform’s components
Delayed discovery of software defects due to time-consuming manual testing
Lack of component versioning and change management processes
Insufficient release management with minimal planning, which resulted in Big Bang releases

The combination of these issues translated into the late detection of software defects, which required approximately 6+ months to fix, along with prolonged development of new features that typically took 3+ months to complete. Therefore, the client decided to upgrade its QA practice and leverage automated testing to improve the software quality and prevent failures in advance, optimize the development time, and accelerate the product time-to-market.

Solution & Business Value

Infopulse created a custom QA strategy for the client, optimized the company’s entire Software Testing Lifecycle (STLC), and implemented various types of software tests that are fully automated, atomic, repeatable, and subdivided by levels. As a result, the refined and mature QA practice has brought a myriad of valuable benefits for Tietoevry Banking:

Automated tests were integrated into the CI/CD pipeline, which ensured the continuous testing of the code during the development process
Standardized release management that enabled fast, consistent, and error-free deployments
Better software and requirements quality through well-defined standards
Overall test coverage increased from 80% to 96%
No major integration issues were observed after the implementation of automated tests
After introducing shift-left testing the number of defects was reduced from dozens to 1-5 a month
98% of software defects are detected before the components are released
The average time to fix software defects was reduced from 6 months to just up to 4 days
Fully automated testing of code merges, which previously had required 8-12 hours of manual testing each day
Automated regression tests spared 1,5 weeks per employee for checking the functionality of new components

Ultimately, the client managed to improve the reliability and performance of its core banking platform, accelerate time-to-market, and optimize a significant amount of costs by detecting and fixing software defects prior to deployment.

Technical Details

At the beginning of the project, Infopulse conducted an in-depth assessment of the client’s QA approach, processes, and software testing tools. After gaining a clear picture of the client’s STLC, our experts shaped a tailored QA strategy with an emphasis on test automation. Once the new strategy was confirmed with the client, Infopulse started implementing DevOps practices and built a dedicated CI/CD pipeline to apply automated tests for every created code merge. In addition, all of the new software requirements were analyzed for completeness, correctness, consistency, and testability.

Consequently, Infopulse experts implemented a range of purpose-built automated tests for Tietoevry Banking:

Unit tests to test the error case scenarios in user stories
Component tests to assess whether the component logic is implemented correctly
System tests to ensure error-free integrations and E2E scenarios
GUI tests to evaluate new features and visual elements
Regression tests to check the entire functionality of all merged components
Smoke tests during daily CI/CD runs to detect major software flaws before deployment

Furthermore, our team established mandatory versioning and change management for all software components, implemented static documentation testing for the created use cases and user stories, and enabled backward compatibility for the platform’s services and APIs.
