Why are automated tests essential?
In the world of agile development, delivering software with quality and speed is no longer an advantage—it's a requirement. Automated tests ensure that the product works as expected even after several changes. Among modern tools, Playwright stands out for its robustness, speed, and ability to simulate complex scenarios.
What is Playwright?
Playwright is a Microsoft open source tool that allows writing E2E (end-to-end) tests reliably. Unlike solutions like Selenium or Cypress, Playwright offers native support for multiple browsers (Chromium, Firefox, and WebKit), complete control over the browser environment, and easy integration with CI/CD pipelines.
Main advantages of Playwright:
- Real cross-browser tests
- Native support for multiple languages (JavaScript, TypeScript, Python, C#, and Java)
- Simulation of geolocation, permissions, and authentication
- Headless and headful with screenshots and videos
