8,000 test cases migrated, full regression from 24 hours to 5

A German statutory pension provider · Public sector · statutory pension insurance

How a German statutory pension provider moved large, grown regression portfolios from Tosca Classic to TBox, corrected test design along the way, and kept a business-critical Win32 application automatable.

The situation

The provider's quality and test management department runs a dedicated team for test management and test automation with Tricentis Tosca. The regression portfolios of several applications had grown on the Tosca Classic engine; the core application, a separate Win32 system, carries more than 1,000 of the most important end-to-end test cases. The goal: move the grown portfolios to TBox, make the regression faster and more robust, and keep the business-critical Win32 front end automatable.

What we did

Migration of 8,000+ test cases (around 100,000 test steps) from Tosca Classic to TBox modules across several application projects
Review of test case design during the migration: wrong designs and missing business focus corrected
Around 30 customizations and custom code to reduce manual effort
Engine customization for the Win32 core application, maintained and further developed
Execution optimization of the regression portfolio
Tosca consulting for the central test automation team, plus follow-up analysis of UIA / Vision AI and support with the qTest selection

Results

Full regression runtime reduced from 24 hours to 5 hours
Faster, more robust test cases on TBox modules
Test case design errors found and corrected during the migration
Less manual effort through custom code

What transfers to your project

Migrating thousands of test cases while improving their design, and automating a business-critical legacy front end with engine-level customizations, with a measurably faster regression at the end.
