🏦 National Australia Bank: A Journey of Performance & Automated Testing Excellence

For over seven years, Enigma Solutions played a critical role in strengthening the quality and reliability of key financial applications at National Australia Bank (NAB), one of the largest and most technology-forward banking institutions in the Asia-Pacific region. As Senior Performance and Automation Testing Consultants, our mission was clear: ensure the stability, security, and performance of NAB’s most vital financial systems — from FX trading platforms to complex mortgage applications.

🔐 Load Testing Secure FX Derivatives Exchange Platform (nabCapital)

One of the standout achievements of our engagement was the successful automation and load testing of NAB’s secure FX derivatives web application, nabCapital — a platform where performance, security, and scalability were non-negotiable.

💼 Project Highlights:

• Technology Stack: SSL-secured web application with digital certificate-based authentication
• Testing Tools:
  • QA Load for load testing in a Citrix environment
  • WinRunner for dynamic digital certificate import
• Virtual User Simulation: Simulated up to 300 concurrent users, each requiring a unique digital certificate
• Test Focus Areas:
  • Load testing under normal and peak user scenarios
  • Failover testing by bringing clustered servers offline mid-test
  • Load balancing validation to ensure even distribution across web and app layers

Through carefully orchestrated tests, Enigma Solutions provided clear performance benchmarks, revealed bottlenecks under secure authentication scenarios, and validated the bank’s infrastructure resilience under failure conditions.

🧠 Advanced Automation in Mortgage Applications (Siebel Financial Services)

In addition to FX systems, Enigma Solutions also automated core workflows in NAB’s Siebel-based mortgage application, which was central to the bank’s lending operations.

🚀 Key Contributions:

• Automated UAT test cases using WinRunner, scripted and managed via TestDirector
• Developed custom Siebel-specific functions to handle dynamic business logic and UI elements
• Conducted performance network testing to assess client-server communication under load
• Maintained and updated a centralized repository of reusable scripts and test functions
• Delivered clear, actionable documentation to support test coverage and traceability

By implementing robust automation across UAT and regression cycles, we helped NAB drastically reduce testing time, improve release confidence, and increase defect traceability in production-like environments.

📅 Non-Functional Test Planning and Delivery Scheduling

Our involvement extended beyond execution into the planning and management of non-functional testing. Working closely with project managers and infrastructure teams, we:

• Scheduled and aligned performance test windows with release delivery milestones
• Advised on environment readiness, capacity planning, and SLA alignment
• Ensured test coverage for failover, recovery, and load scenarios across critical components

🧩 Strategic Impact: Building Performance into the Culture

What made Enigma’s engagement at NAB unique wasn’t just the testing — it was the culture of performance awareness and risk-based planning we helped instill across teams. Developers, business analysts, and project leads were trained to think performance-first, ensuring long-term scalability and stability were baked into each release.

🔚 Conclusion

Enigma Solutions’ long-term engagement with National Australia Bank reflects our unwavering commitment to technical excellence, security-conscious design, and performance-driven testing. Whether it was simulating hundreds of secure users with digital certificates or automating complex business flows in Siebel, our team consistently delivered solutions that enabled NAB to move fast without sacrificing stability or trust.
