Accelerating Quality at Scale: Continuous Testing for a Global Payments Leader

Background: 

A global payments technology leader supporting over 800,000 merchant locations and 1,400+ financial institutions set out on a journey to modernize its QA landscape. After a major merger and rapid digital expansion, the organization aimed to adopt Agile and DevOps practices while accelerating software delivery and mitigating business risk. 

To succeed, the company needed a scalable, automation-driven QA transformation to shift testing left, reduce release times, and improve business risk coverage across mission-critical applications. 

Challenges: 

• Transitioning from Waterfall to Agile, where legacy test practices could not meet 2-week sprint timelines. 

• Tens of thousands of legacy HPE UFT tests created high maintenance overhead and insufficient risk coverage. 

• Regression testing cycles lasting over 8 weeks. 

• High manual testing costs and inconsistent test data environments. 

• Continuous Delivery required embedding Continuous Testing into DevOps pipelines. 

Solution: 

Narwal partnered with the company to build a future-ready QA ecosystem: 

• Integrated CD/CT pipelines to enable Continuous Testing at scale. 

• Shifted to Module-Based Tests, reducing test suite from 30,000 to 5,000. 

• Implemented overnight smoke tests for real-time quality feedback. 

• Introduced risk-based testing to focus on high-priority scenarios. 

• Enabled early defect detection with in-sprint automation practices. 

• Built synthetic test data to solve test environment lag. 

• Established centralized QA governance to enhance transparency and Dev collaboration. 

Business Outcomes: 

• Test Automation Coverage: Increased from 5% to 80%. 

• Business Risk Coverage: Jumped from 23% to 82%. 

• E2E Execution Time: Reduced from 8 weeks to 1 week. 

• Regression Suite Time (SFDC): Reduced from 1 week to 10 hours. 

• Test Coverage (SFDC): Improved from unknown to 95%. 

• Defect Prevention: On average, 20 defects prevented per release cycle. 

• Transparency: Full visibility through maturity dashboards and metrics.
