A Leading European Retail Bank Subsidiary Ensures a Highly Responsive Digital Experience for its 2M Customers With Specialized Quality Engineering
About the Client
Our client is a subsidiary of a leading European retail bank with an unrivaled distribution network in the UK, serving close to two million customers. They offer a portfolio of mortgage, savings, and loan financial products through local partnerships.
Business Needs
The retail bank embarked on a multi-year restructuring program to transform its UK operations into an agile, efficient entity with a reduced cost base. Under this program, the organization consolidated systems, streamlined back office processes of its Loan and Savings product lines, and simplified customer journeys.
The new operating model covered more than 40 functional and system-level integrations with the loans and savings product lines. They wanted to ensure that applications perform as expected even with bandwidth constraints, as well as:
Assess the performance of all front-end applications
Capture data for responsiveness, stability, and server utilization
Identify and resolve performance bottlenecks of the new solution
Trigent Solution
Investing in continuous testing services was essential as the client consolidated 40+ systems and integrations across product lines. The unified solution required every change to be comprehensively validated across systems and processes. Trigent’s team, with over 30 years of industry and technical experience, expedited the design and setup of the Test framework in the pre-production environment.
The Trigent team created a web application test suite to validate the customer portals. Besides Functional Testing, non-Functional Tests verified response time, throughput error rate, CPU, and memory usage. Performance tests, such as smoke, benchmark, iterative load, stress, endurance, spike, and volume tests, were done to assess end-to-end application responsiveness. The development team would alter the design and hardware configuration based on the dry-run results.
API performance testing strategy ensured the proper functioning of the programming interfaces.SIT, and UAT environments were used for test execution. A series of iterative tests for varying loads were conducted, and the team generated interim performance reports encapsulating:
- Summary of the test runs
- Key findings
- Measurable success criteria of each test
Client Benefits
The sound performance testing strategy enabled the organization to:
- Rollout a unified customer portal serving close to two million customers
- Reduce error to less than 2%
- Increase the concurrent login request to 2,000 requests
