🎭 Playwright — Modern Browser Automation

What you can learn on this page

• 🎭 What is Playwright? Why Use It? — Think of Playwright like a game controller. You press buttons (test code), the controller (Playwright) sends the signal, and the game character on screen (browser) reacts. Selenium does the same thing but Playwright is a "smarter" controller — it aut
• ⚙️ Installation — TypeScript · Java · Python — Installing Playwright is like assembling IKEA furniture. For TypeScript, one command downloads everything (browsers included). For Java, add a dependency to pom.xml. For Python, pip install + playwright install — two steps, done. 1️⃣ TypeScript / JavaScript Se
• 🖱️ Basic Actions — Selenium Comparison — In Selenium, every action was two steps: "find element, then act on it." In Playwright, you define a locator once and call the action directly — and it automatically waits for the element to be ready. All Actions — 3-Language Comparison

• 📁 File · Network · API Mock — In Selenium you needed a separate proxy to intercept API calls or return fake responses. In Playwright, page.route() lets you replace any API response in a single line — as if the real server responded. Which method in Playwright intercepts an API call and ret
• 🌍 Real World — E-Commerce Full Scenario — Imagine you're a real QA engineer. Your task: test the "user logs in, searches for a product, adds to cart, completes payment" flow. Below is the full implementation of this scenario in TypeScript, Java, and Python.
