Overview:
A global leader in the financial services industry, operating in a complex technology landscape with microservices, ERP, Salesforce, and a multitude of internal and external API integrations. The client faced significant challenges in maintaining seamless integration testing due to dependencies on multiple external systems and stringent regulatory compliance requirements.
Challenges:
- High Failure Rates: Integration test cases were experiencing above-average failure rates due to the complexity and lack of control over external systems.
- System Dependencies: Testing was frequently delayed by dependencies on external systems that were available only in limited capacity or prone to unplanned outages.
- Slowness in Certification Testing: Stringent timelines for regulatory compliance and legal requirements made it difficult to cover all critical test cases during the certification phase, resulting in delayed approvals.
Solution:
To address these challenges, Birlasoft proposed an Integration Testing Solution as part of our AI-powered unified automation platform Birlasoft LynX. The framework featured:
- Service Virtualization: Allowed the team to create dynamic mock services that mimicked real service behaviours. This eliminated dependencies on external system availability by simulating external/internal services, enabling early integration testing without waiting for live system availability.
- Self-Serving Library: A comprehensive library of all services was created, enabling the team to manage and reuse the virtualized services easily.
- Dynamic Stubs: Replacing static stubs with dynamic mimicking services allowed for more realistic test scenarios, preventing the use of outdated or inaccurate data during testing.
Key Features of the Solution:
- Mitigated Dependencies: Virtualized services allowed the test team to bypass external system unavailability, enabling early System Integration Testing (SIT) and removing bottlenecks caused by system dependencies.
- Comprehensive Services Coverage: The solution provided full coverage for services passing through Apigee and PCF, ensuring comprehensive integration testing across all services and removing the delays that had previously affected testing schedules.
- Accelerated Certification Testing: Early certification testing became possible by running tests on the virtualized services without waiting for dependent systems to become available, helping to mitigate the risk of compliance failures and enabling timely certification approvals.
Results:
- Reduction in Testing Delays: By eliminating dependencies on external systems, integration testing was accelerated, significantly reducing delays caused by system unavailability.
- 25% Faster Time-to-Market: The optimized testing process allowed for comprehensive testing in a shorter time frame, ensuring faster releases while maintaining full compliance with regulatory requirements.
- Greater Test Coverage: The virtualized services and dynamic stubs allowed for enhanced test coverage within the limited window available for certification testing, ensuring all critical areas were thoroughly tested.
Conclusion
Birlasoft’s service virtualization, as a part of Birlasoft LynX approach, transformed the client’s integration testing capabilities, allowing for greater efficiency, faster releases, and improved test coverage without relying on external systems. The solution not only reduced time-to-market but also minimized the risks of regulatory non-compliance, making it an essential tool for ensuring seamless operations in complex system architectures.
