Playwright Python Hindi #7 - Sync vs Async API, Browser Context & Pytest Fixtures Tutorial

🚀 Learn Playwright with Python Pytest Framework — Sync API, Browser Context, Fixtures & Headless vs Headed execution explained step-by-step with real examples for QA automation engineers. In this episode of the Playwright with Python series, we deep dive into the Pytest-Playwright integration, exploring how to verify installations, create your first test case, understand Synchronous vs Asynchronous APIs, launch browsers in Headless and Headed mode, and master Browser Context for handling multiple sessions like Incognito windows. Whether you're a beginner stepping into automation testing or a QA engineer transitioning from Selenium, this tutorial gives you hands-on practical knowledge that directly applies to real-world QA jobs and interview questions. 📌 KEY TOPICS COVERED: ✅ Verifying Playwright & Pytest installation via pip show ✅ Installing Pytest-Playwright plugin (integration setup) ✅ Pytest naming rules — why test_ prefix matters for files & functions ✅ Playwright Sync API vs Async API — when to use which (90/10 rule) ✅ Writing your first test case using the Page fixture ✅ Getting page title & applying assertions (assert) ✅ Running tests via Run Mode vs Terminal/Command Line ✅ Headless vs Headed execution — CI/CD pipeline use cases ✅ Launching browsers in Chromium, Chrome, Firefox ✅ Two ways to write Playwright scripts — Page fixture vs Playwright fixture ✅ Browser Context — handling incognito sessions & multi-user logins ✅ Page navigation: goto, go_back, go_forward, reload ✅ Setting viewport size (set_viewport_size) for window resolution ✅ Codegen — Record & Play feature with role-based locators ✅ Pytest Markers vs Custom Tags (built-in vs user-defined) ✅ Interview-ready concepts: Why headless is faster, fixtures explained ⏱️ TIMESTAMPS 00:00 Introduction & Recap of Installation Setup 01:33 Verifying Pytest-Playwright Plugin Installation 02:31 Creating Test Directory & First Test File 04:44 Playwright Sync API vs Async API Explained 07:20 Importing sync_playwright & Writing First Function 09:01 Using Page Fixture to Open URL & Get Title 11:52 Applying Assertions in Pytest 13:25 Running the Test — Headless Execution by Default 15:44 Configuring Headed Mode (Chromium, Firefox) 18:52 Headless vs Headed — CI/CD & Interview Question 20:51 Understanding Playwright Sync API as Package 22:53 Page as Class, Instance & Fixture — Full Concept 28:00 Pytest Naming Rules (test_ prefix) 34:43 Second Approach — Using Playwright Fixture Directly 40:28 Browser Context — Incognito Window Concept 43:48 Running Tests via Terminal Command Line 50:55 Page Navigation — goto, go_back, go_forward, reload 54:03 Setting Viewport Size (set_viewport_size) 57:35 Playwright Codegen — Record & Play Feature 1:00:48 Custom Fixtures, Markers vs Tags 1:05:53 Conftest.py Overview 1:06:55 Browser Context Use Case — Multi-User Login Sessions 1:13:54 Wrap Up & Documentation Resources 📢 CTA — JOIN THE JOURNEY! 🔔 SUBSCRIBE for the complete Playwright with Python series 👍 LIKE if this tutorial helped you understand Pytest-Playwright integration 💬 COMMENT your questions — I reply to every one! 🔄 SHARE with fellow QA engineers & automation testers 🎯 Your automation career starts with one tutorial — stay consistent, practice daily, and you'll crack that QA Automation interview! #playwrightpython #playwrighttutorial #automationtesting #pytestframework #pythonautomation #qaengineer #seleniumalternative #webautomation #testautomation #pytestplaywright #softwaretesting #qatesting #browserautomation #headlessbrowser #syncvsasync #playwrightfixtures #qatestingjobs #learncoding #automationtester #codeneration
