 In the fast-paced world of web development, functionality is paramount, but so is visual integrity. A button that works perfectly but is misaligned, text that's readable but the wrong font size, or a broken layout can severely impact user experience and brand perception. Functional tests, while essential, often miss these subtle yet critical visual defects. This is where Visual Regression Testing (VRT) comes into play. VRT ensures that your application's UI remains pixel-perfect and consistent across releases, browsers, and devices. And for modern web automation, Playwright offers powerful, built-in capabilities to make VRT not just possible, but efficient. This blog post will guide you through mastering visual regression testing with Playwright, ensuring your application always looks exactly as intended. What is Visual Regression Testing? Visual Regression Testing is a testing technique that compares screenshots of a web page or component against a "baseline" (or ...

  In today's digital-first world, your web application isn't truly "done" unless it's accessible to everyone. Accessibility testing (often shortened to A11y testing) ensures that your software can be used by people with a wide range of abilities and disabilities, including visual impairments, hearing loss, motor difficulties, and cognitive disabilities. Beyond legal compliance (like WCAG guidelines), building accessible applications means reaching a broader audience, enhancing user experience for all, and demonstrating ethical design. While manual accessibility testing (e.g., using screen readers, keyboard navigation) is crucial, automating parts of it can significantly accelerate your efforts and catch common issues early. This is where Playwright , a modern and powerful web automation framework, combined with dedicated accessibility tools, comes in. This guide will provide a practical approach to integrating automated accessibility checks into your Playwright te...

Magento applications, with their rich UIs, extensive JavaScript, and reliance on AJAX, often pose unique challenges for test automation. While Playwright's intelligent auto-waiting handles many scenarios, the dynamic nature of Magento's storefront and admin panels demands more sophisticated waiting strategies. This guide explores specific Playwright waiting mechanisms that are particularly effective when automating tests on a Magento base application.                                        1. Embracing Playwright's Auto-Waiting (The Foundation) First and foremost, always leverage Playwright's built-in auto-waiting for actions. This means that when you perform a click() , fill() , check() , etc., Playwright automatically waits for the element to be visible, enabled, stable, and receive events before attempting the action. This is your primary defense against flakiness. JavaScript // Playwr...

When you embark on a Playwright test automation journey, you quickly encounter playwright.config.js . This seemingly humble JavaScript file is, in fact, the central control panel for your entire test suite. It's where you configure browsers, define parallel execution, set timeouts, integrate reporters, and manage various test environments. Understanding playwright.config.js is crucial because it dictates the behavior of your tests without needing to modify individual test files. This makes your framework incredibly flexible, scalable, and adaptable to different testing needs. Let's unravel the key sections of this powerful configuration file. What is playwright.config.js ? At its core, playwright.config.js is a Node.js module that exports a configuration object. Playwright's test runner reads this file to understand: Where to find your tests. Which browsers to run tests on. How many tests to run in parallel. How to report test results. Various timeouts and debugging optio...
