THE VISION

Driving digital transformation with confidence

Amret, a leading Cambodian financial institution owned by Bank SinoPac, embarked on a strategic journey to transform into a full commercial bank. Central to this transformation was the upgrade of its core banking system (CBS) to Temenos Transact (T24-R18) — a robust platform enabling modern banking services across Loans, Teller, and Deposits modules.

To ensure the success of this large-scale initiative, Amret needed a reliable, repeatable, and scalable testing framework to validate system performance across multiple modules, channels, and integrations. The goal: achieve faster releases, higher quality assurance, and full confidence in every deployment.

THE CHALLENGE

Manual testing slowing down transformation

Before adopting Katalon, Amret’s QA process relied heavily on manual testing, which made validation slow, inconsistent, and error-prone.
Each T24 workflow required precise data entry, validation, and execution across multiple configurations and modules. Without automation, repeatable regression testing was nearly impossible, consuming excessive time and resources.

The complexity of T24’s setup — with interdependent modules and dynamic data requirements — further increased the manual effort and risk of human error, limiting the team’s ability to scale testing as new features and updates were rolled out.

The Solution

Automating T24 testing 
end-to-end with Katalon

Amret implemented Katalon’s quality management platform to fully automate testing across web, API, and mobile channels, seamlessly integrated into its CI/CD pipelines.

The QA team built a modular, data-driven automation framework, leveraging Katalon Studio’s flexibility to:
  • Record real T24 workflows (Customer, Account, Deposits, Loans, etc.) as reusable test libraries
  • Generate AI-powered test data instantly, aligned with T24’s field templates
  • Run large-scale executions automatically pulling data files and authenticating into T24
  • Capture full execution logs, including screenshots, videos, and error messages for instant triage
This unified approach ensured fast setup, low maintenance, and consistent test coverage across all T24 modules — even as configurations evolved.

The Results

Accelerating delivery with zero manual effort

Katalon’s automation has allowed us to test faster, with higher coverage and no manual overhead. We can now run repeatable regression cycles with full visibility into results and instant error diagnostics.”

By adopting Katalon, Amret achieved measurable efficiency gains across all core banking flows:

  • 174 reusable test libraries built across 9 key T24 modules
  • 70%–93% reduction in testing time across all modules
  • 90%+ faster data setup with AI-generated datasets — eliminating manual data entry
  • Zero-touch execution through fully automated pipelines
  • Rapid triage and debugging with detailed logs, screenshots, and videos

Katalon transformed testing from a bottleneck into a strategic enabler of faster, higher-quality releases. The platform’s AI-powered test data creation, automated regression cycles, and reusable assets now allow Amret to deliver updates with confidence, speed, and scale — all while reducing maintenance and human error.

Building on this foundation, Amret is extending its automated libraries to support T24-R25 and expanding Katalon’s coverage to mobile banking, internal tools, and API testing — all within a single, unified platform that continues to drive the bank’s digital transformation forward.

Your automation journey starts here.
