In the ever-evolving world of software development, ensuring that web applications function seamlessly across browsers, devices, and platforms is no longer a luxury—it’s a necessity. Traditional automation tools like Selenium and Cypress have paved the way, but a new era of intelligent automation is here: Playwright.
