De-risking an SAP S/4HANA finance migration
In a core-banking finance transformation from SAP ECC to S/4HANA (with Fiori), we ran the automated data-migration validation in Tricentis Tosca, reconciling source against target table-by-table and transaction-by-transaction, with the migration's own transformation rules embedded so expected changes never surfaced as false failures. Reusable Header/Item templates scaled one validation across all 25 booking entities, each with its own audit-signed sign-off.
Read →One regression template, from 10 pilot plants to 70 worldwide
Production runs on SAP Digital Manufacturing, integrated with PP, MM and FI/CO. Instead of plant-by-plant manual testing, we built one Tosca regression template for 10 pilot plants and then rolled it out to 70 plants worldwide, with uniform test data for every plant, CI/CD via Jenkins and enablement of the local teams.
Read →Release testing and SAP IS-U automation, re-awarded since 2023
For the transport and grid companies of a municipal utilities group, a dedicated test team covers release testing of workplace, infrastructure and SAP updates, and automates SAP IS-U processes such as market communication, meter installation and house connections end to end in Tricentis Tosca. 240 business processes now run as automated regression, and business users spend 65% less time testing each release.
Read →8,000 test cases migrated, full regression from 24 hours to 5
The regression portfolios of several applications had grown on Tosca's Classic engine. We migrated more than 8,000 test cases (around 100,000 test steps) to TBox modules, correcting test-case design along the way, added around 30 customizations to cut manual effort, and kept the business-critical Win32 core application automatable through engine-level customization.
Read →A custom Tosca engine for gRPC services, built from scratch
A key public programme delivered by four or more contractors chose Tricentis Tosca as its common test tool, but Tosca's API engine supported neither gRPC nor protobuf. We built a custom Tosca engine from scratch, plus a scanner that turns .proto definitions into Tosca modules, so testers build model-based gRPC tests without programming.
Read →From quarterly to monthly releases in digital banking
Facing a rapidly evolving mobile and e-banking platform, the firm replaced manual testing and a legacy script-based tool with risk-based, model-based automation in Tricentis Tosca: reusable modules, template-based test cases, central test data and service virtualization for the surrounding systems. The test window per release halved, and releases moved from quarterly to monthly.

Since June 2025 the EAA makes accessibility a legal requirement for many digital services in the EU. Who is affected, what WCAG 2.1 AA means in practice, and how to test for it.
Read →Getting test data under control: a pragmatic how-to
Many 'flaky' tests aren't flaky at all: they're starved of reliable test data. Four data classes, four principles and five steps to fix the quiet killer of test suites.
Read →Which test automation tool fits when?
Tosca, UiPath, Playwright, Postman: the useful question isn't which tool is 'best', but which fits your landscape. A vendor-neutral decision guide.
Read →Shift-left testing: where to start
Shift-left isn't a tool you buy; it's moving quality decisions to where they're cheapest. A pragmatic way to begin.
Read →Testing SAP S/4HANA migrations without the risk
With ECC mainstream maintenance ending in 2027, S/4HANA moves are accelerating, and testing is where they succeed or stall.
Read →AI in software testing: hype vs. what actually works
2026's buzzword is 'agentic testing'. Some of it is genuine leverage; some is marketing. Here's how to tell them apart.

SAP screens, cross-module processes, a constant stream of transports: why classic UI automation fails on SAP and how a model-based approach with Tosca holds up.
