How Migrating from Selenium to Playwright Reduced Regression Testing from 4 Hours to 50 Minutes?

Qeagle — Testing Service Company

As organizations embrace faster release cycles and agile development practices, traditional automation frameworks often struggle to keep pace. One of our clients faced growing challenges with their Selenium-based automation framework, including flaky tests, lengthy execution times, and increasing maintenance overhead.

To address these challenges, Qeagle led a strategic migration from Selenium to Playwright, enabling the client to achieve significantly faster, more stable, and scalable test automation.

The Challenge

The client’s web application, built using modern Angular components, frequently encountered synchronization issues with Selenium. This resulted in unstable test executions and a high volume of false failures.

Several additional challenges impacted overall delivery efficiency:

• Regression execution cycles required 3–4 hours to complete.
• Test stability remained around 70%, creating uncertainty in release decisions.
• Browser coverage was largely limited to Chrome, with additional browsers requiring complex Selenium Grid configurations.
• Framework maintenance became increasingly difficult as the application evolved.

These issues slowed CI/CD pipelines and reduced confidence in automated quality validation.

The Migration Strategy

Rather than performing a large-scale framework replacement, the migration was executed through a phased approach designed to minimize risk and maximize business value.

1. Assessment and Planning

The team conducted a detailed analysis of the existing Selenium framework to identify reusable assets, obsolete components, and opportunities for modernization.

Migration priorities were established as:

• Critical business workflows
• Regression suite
• Smoke and integration test scenarios

This phased approach ensured continuous test coverage throughout the transition.

2. Building a Modern Playwright Framework

A new TypeScript-based Playwright framework was developed with scalability and maintainability in mind.

Key improvements included:

• Adoption of Playwright Test Runner
• Implementation of a structured Page Object Model (POM)
• Utilization of Playwright’s intelligent auto-waiting capabilities
• Integration of screenshots, video recording, and trace viewer for faster debugging

These enhancements significantly reduced test flakiness while improving developer productivity.

3. CI/CD and Parallel Execution

Playwright’s native parallel execution capabilities enabled substantial performance improvements.

The framework was integrated with Azure DevOps pipelines to support:

• Automated pull-request validation
• Scheduled regression execution
• Real-time reporting and notifications
• Faster feedback loops for development teams

4. Team Adoption and Enablement

Technology transformation is successful only when teams embrace it.

To ensure a smooth transition, training sessions and hands-on workshops were conducted for QA engineers. Updated documentation and onboarding guides helped accelerate adoption across teams.

Results Achieved

The migration delivered measurable improvements across quality, speed, and maintainability.

Key Business Benefits

The transition to Playwright generated benefits beyond technical improvements:

• Reduced regression execution time by more than 70%.
• Increased test reliability and confidence in release decisions.
• Faster developer feedback during pull request validation.
• Improved collaboration between development and QA teams.
• Simplified framework maintenance and onboarding.
• Lower infrastructure costs through the removal of Selenium Grid dependencies.
• Enhanced cross-browser coverage without additional configuration complexity.

Conclusion

Modern software delivery requires automation frameworks that are fast, reliable, and easy to maintain. By migrating from Selenium to Playwright, the client transformed their testing strategy, significantly improving execution speed, stability, and overall engineering efficiency.

The initiative demonstrates how the right automation platform can help organizations accelerate releases, reduce quality risks, and build a stronger foundation for continuous delivery.
