Accelerating desktop testing with 90% regression automation coverage

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.

Key challenges included: 

• Time-consuming regression cycles 
  Manual validation across multiple product versions slowed release readiness and extended testing timelines.
• High dependency on SMEs 
  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.
• Limited scalability and coverage 
  As the product landscape grew, expanding regression coverage required significant additional effort and resources. 

Nagarro implemented a scalable desktop automation framework with TestComplete and TestExecute. In three months, a focused offshore team introduced reusable components, selective execution, and integrated reporting to improve regression efficiency and maintainability.

The solution included:

• End-to-end desktop automation
  Automated complex workflows across multiple product versions using TestComplete’s UI recognition, object mapping, and scripting capabilities.
• Selective test execution
  Introduced tagging-based execution to run targeted test suites and reduce overall execution time.
• Reusable automation framework
  Built a modular framework with reusable components and libraries to support easier maintenance and future expansion.

• Integrated reporting and diagnostics
  Enabled detailed reporting and actionable failure insights to support faster debugging and quality metrics.

The initiative shifted regression testing from manual effort to a faster, more reliable quality engineering model. It improved coverage, reduced manual execution, accelerated feedback cycles, and strengthened release confidence across product versions.

Key benefits included:

• 206 test cases automated 
  Critical regression scenarios across the desktop application ecosystem were automated.
• 90%+ automation coverage achieved 
  The client gained broader and more consistent validation across key regression scenarios.

• Faster feedback and release cycles

  Automated execution accelerated defect identification and supported quicker release readiness.

• Reduced manual effort and better scalability

  SMEs were freed from repetitive testing, while knowledge transfer enabled internal teams to extend the framework to new versions and features.
