SAP S/4HANA Test Automation with TOSCA
Implemented end-to-end test automation for a large-scale SAP S/4HANA migration using Tricentis TOSCA, achieving 80% automation coverage and reducing regression testing from 3 weeks to just 3 days.
The Challenge
A global manufacturing enterprise was migrating from SAP ECC to S/4HANA across 12 countries. The migration involved 2,500+ critical business processes spanning Finance (FICO), Materials Management (MM), Sales & Distribution (SD), Production Planning (PP), and Warehouse Management (WM) modules.
Manual regression testing required 3 weeks per cycle with a team of 45 testers, creating bottlenecks that delayed the go-live timeline. Test coverage was inconsistent, with only 40% of critical scenarios being tested in each cycle. The client needed a scalable automation solution to ensure quality while meeting aggressive timelines.
Key Pain Points
- 3-week regression cycles delaying go-live across 12 countries
- Only 40% test coverage of critical business processes per cycle
- 45 manual testers unable to keep pace with frequent transport releases
- Inconsistent test data management across multiple SAP environments
- No traceability between business requirements and test execution
