GenAI Automates Test Cases for 600+ Customer Communications

From manual test authoring to 70% less effort with GenAI.

A Tier-1 Global Bank partnered with Kumaran to automate test case and script generation for over 600 printed customer communication letters, achieving 70–85% automation accuracy and reducing manual effort by 70%. The engagement delivered a GenAI multi-agent solution — a Test Case Generator and Test Executor — that automated the full validation pipeline for customer communications in PDF format. For this bank, the challenge was not just volume — it was the precision required to validate formatting, text positioning, and layout against strict print specifications, at a scale that manual authoring simply could not sustain.

The Background

The bank produced hundreds of printed customer communication letters that had to strictly adhere to detailed print specifications. Every letter required test cases covering formatting, text positioning, images, and content accuracy — all written manually by the client's QA team. As communication volumes grew, the manual effort became unsustainable, creating bottlenecks in the release pipeline and increasing the risk of specification non-compliance. A scalable, automated approach to test generation and validation was essential.
