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.

The business challenge

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.
flash-1

In short

  • Every release meant weeks of manual regression across multiple product versions — dependent on scarce experts, prone to inconsistency, and harder to scale with each new version. 
  • Time-consuming regression cycles
    Manual validation across multiple product versions slowed release readiness and extended testing timelines. 
  • Selective test execution
    Functional experts were required for repetitive regression checks, limiting their availability to focus on innovation and complex validation. 
  • Inconsistent execution
    Manual processes increased the risk of human error, missed defects, and inconsistent test outcomes. 

What every release cost, before automation

  • Effort per regression cycle (illustrative share) — the same manual loop, repeated for every product version
  • Group 1-1

  1. Release speed

    Before · manual regression Manual validation across versions slowed release readiness

    After · automation-first Automated execution accelerates defect identification

  2. Expert time

    Before · manual regression SMEs tied up in repetitive regression checks

    After · automation-first SMEs freed to focus on innovation and complex validation

Customer quote

By combining the right automation strategy with a reusable TestComplete framework, we helped the client move from effort-heavy manual regression testing to a scalable, high-coverage quality engineering model — enabling faster validation, improved consistency, and a stronger foundation for future releases.
