About Our Client
Our client is a major financial institution operating across North America, with a network of 300+ branches and a rapidly evolving digital infrastructure. They developed a secure desktop application to handle internal transaction processing, role-based access control, audit tracking, and compliance with federal banking regulations.
Challenge
The desktop software was mission-critical and complex, but the client faced key issues:
- OS Compatibility Gaps: The app behaved inconsistently across Windows 10, Windows 11, and legacy Windows Server environments.
- Multi-Role Functionality: Different user roles (Teller, Branch Manager, Auditor) had unique workflows and data access, which were prone to privilege-related bugs.
- Security Requirements: The platform needed validation for data encryption, session timeouts, and secure offline/online transaction syncing.
- Limited Automation Coverage: Most tests were manual, time-consuming, and lacked coverage for regression and integration scenarios.
- Audit & Compliance Mandates: The bank required rigorous traceability and validation logs for all test executions.
Solution
Celestial Infosoft deployed a multi-skilled QA team to deliver functional, compatibility, and security testing services tailored for enterprise desktop systems.
Key Features Delivered:
- Cross-OS Compatibility Testing: Validated UI/UX, system services, and drivers across multiple Windows OS versions and VM environments.
- Role-Based Functional Testing: Designed over 250+ test cases to verify role permissions, audit logs, and restricted module access.
- Security Validation: Performed static and dynamic tests for encryption flows, secure session handling, and sensitive data masking.
- Test Automation Setup: Implemented desktop automation using TestComplete and Selenium (for hybrid modules with web components).
- End-to-End Integration Testing: Ensured stable communication between the desktop app, backend systems, and banking APIs.
- Traceable Test Reports: All test cases, logs, and defects were managed and traceable via Azure DevOps with compliance-ready reports.
