at a glance

The numbers speak for themselves

Within three months, a focused offshore team automated 206 regression test cases and achieved more than 90% automation coverage across critical scenarios — accelerating feedback cycles, reducing manual effort, and improving release confidence, while creating a scalable testing foundation for future product versions and features.
the story

Who is the customer — and what was at stake?

A global leader in energy management and industrial automation needed a faster and more scalable way to validate its desktop-based power management applications across multiple product versions. Manual regression testing was slowing release readiness, increasing dependency on SMEs, and making consistent coverage harder to maintain.


Nagarro introduced an automation-first quality engineering approach using TestComplete and TestExecute. Within three months, a focused offshore team built a reusable desktop automation framework that automated 206 regression test cases and achieved more than 90% automation coverage across critical scenarios.


The initiative led to accelerated feedback cycles, reduced manual effort, and improved release confidence, while creating a scalable testing foundation for future product versions and features.

What was slowing releases down?

The client's growing desktop application ecosystem made regression testing complex and effort-intensive. Manual validation across product versions slowed releases, increased SME dependency, and made consistent coverage difficult to sustain as the landscape expanded.
