What is Playwright?

A Comprehensive Guide to Modern Web Test Automation

In today’s software world, web applications have become increasingly complex due to rapid development cycles, microservice architectures, and continuous delivery pipelines. As a result, maintaining software quality has become more challenging than ever. This is where test automation plays a critical role.

Playwright is a modern end-to-end (E2E) test automation framework developed by Microsoft. It is designed to simulate real user behavior as closely as possible and provides a powerful, reliable, and scalable solution for testing modern web applications.

What makes Playwright stand out is its ability to handle modern UI complexity while remaining fast, stable, and developer-friendly.

Why Was Playwright Created?

Traditional automation tools—especially Selenium-based solutions—started to show limitations over time:

  • Flaky and unstable tests
  • Complex waiting mechanisms
  • Browser compatibility issues
  • Slow execution times
  • Difficult CI/CD integration
  • High maintenance cost

Playwright was built to solve these problems from the ground up.
