The client is a market leader in the trade finance business and handles large volumes of trade. The transformation project was an extremely high-risk and high-visibility program from the perspectives of both the client organization and the financial services industry. This entailed ensuring the highest levels of business assurance to prevent any issues post go-live.
The client had over 100 bespoke legacy and regional systems and silos of data that exhibited lack of maintenance, incurred high cost, and resulted in poor customer advocacy.
Infosys built a quality assurance (QA) strategy based on four key principles:
- Shift-left QA aligned to agile methodology for early and continuous feedback
- Progressive automation to ensure maximum coverage
- Comprehensive test coverage to ensure minimal business impact
- Test asset reuse for multi-country rollout across over 25 countries
This approach resulted in consistent quality and reliability of the software product as well as faster time to market.
Key challenges
- This was a highly complex transformation program with over 100 bespoke systems on legacy technology. Replacing the mainframe-based trade engine integrated with applications on AS400, DB2, and IMS with a modern COTS product involved re-engineering of thousands of complex business rules.
- As a large volume of data was migrated from legacy to the new application, adding to complexity was the thorough migration and comparison testing needed.
- The legacy program was running on multiple tech stacks (React, Angular, process APIs, system APIs, mainframe legacy applications), making it challenging to achieve a high degree of automation.
- To deliver this program successfully, deep knowledge of both bespoke systems and COTS products was required. Creating an effective knowledge management plan and nurturing domain SMEs throughout the tenure of this program was critical.

The Solution
A comprehensive test strategy to achieve digitalization of trades using innovative automation framework and Test Data Management (TDM)
The trade finance domain transformation journey was built on the following innovative testing practices:
- A self-service portal was set up using CA-TDM to extract test data (accounts and customers) from six heterogenous systems and make it available to all test teams
- Developed Infosys API Automation Accelerator (IAAA) IP to achieve 100% in-sprint automation. This solution won a gold award at the Infosys automation open challenge
- Test SMEs created over 35 reusable test templates in the trade finance domain to cover end-to-end business scenarios
- Built a Visual Basic-based comparison utility to validate over 10,000 guarantees, each with over 90 business rules and migrated from mainframe legacy to the new platform
- Built five reusable cloud assets in this program
Engineering excellence initiatives for the trade transformation program
- Reused tests from SIT and UAT for global rollout, reducing overall testing cost by 75%
- Shift left QA resulted in around 60% defects captured early
- Achieved over 90% regression and over 75% in-sprint automation with loosely coupled framework that helped automate UI, API, and back-office applications
- A robust knowledge management plan driven by our in-house learning platform Lex, and external training/certifications helped reduce in-process defects by 20%
