    The engagement

    What was automated, and what it returned.

    Deeply nested plugin software meant nobody could answer a delivery question with confidence: does the whole system still work end to end before this goes to a customer?

    The company

    Who this is about.

    SEW-Eurodrive has been a pioneer in drive and automation technology for over 90 years, and its gearmotors and drive systems run production lines around the world. The company develops its own engineering software, a platform of roughly fifteen highly specialized plugins with deeply nested menus.

    That software ships to the engineers who commission SEW drives in the field, so the delivery question was never whether one plugin works. It was whether the whole system still works end to end, provably, before every release.

    In the world of industrial automation, SEW-Eurodrive stands out as a pioneer-renowned for its commitment to innovation and quality across drive and automation technology for over 90 years.

    The Challenge

    SEW Eurodrive develops their own software with many highly specialized plugins and deeply nested menus. This complexity led to a critical question: How can we test this better? Traditional tools fell short, and performance suffered.

    Before AskUI, SEW Eurodrive only had unit and integration tests. System testing was manual, and the infrastructure for scalable, automated testing simply didn't exist.

    The Solution

    AskUI enabled the company to create full end-to-end system tests across its entire CI/CD process. Today, each of their ~15 specialized plugins is tested via Azure DevOps pipelines, and 30 system tests now cover critical functionality.

    AskUI impressed from the start. It offered excellent performance and a gentle learning curve. Even complex UI scenarios like clicking through 10 nested menus became feasible.

    Results at a Glance

    • System Testing: Automated via pipelines (previously manual, unstructured)
    • Test Coverage: 30 detailed system tests (previously no system tests)
    • Bug Detection: Bugs caught automatically in pipelines (previously many missed post-release bugs)
    • Tool Flexibility: Use of Python and TypeScript (previously manual scripting only)
    • Code Base: 20,000-30,000 lines of modularized test code

    Key Benefits

    ✓ Enables complex system test automation ✓ Flexible scripting with Python & TypeScript ✓ Fast support and product evolution ✓ Delivers real QA value and fewer support issues

    SEW has now relied on AskUI for over three years, and they've seen a decrease in customer support tickets since automation began.
