Playwright BDD with TypeScript | Reusable createTestFunction to Reduce Boilerplate Code

In this tutorial, I walk you through creating a reusable TypeScript utility function called createTestFunction in Playwright BDD to drastically reduce boilerplate code when working with Page Object Models and fixtures. https://github.com/TestRoverAutomation/Playwright_Learning Instead of writing repetitive fixture code for each page object, we build a generic helper that dynamically creates and injects any Page Object into your tests—making your framework clean, scalable, and DRY (Don’t Repeat Yourself). What you’ll learn in this video: ✅ Understanding and implementing generic types in TypeScript for page objects ✅ How the type constraint works: T extends new (page: Page) InstanceType T ✅ Writing a createTestFunction utility to simplify fixture setup ✅ Reducing repetitive fixture code across multiple Page Objects ✅ Using an index.ts barrel file to streamline imports ✅ Implementing BDD-style test steps with Playwright-BDD and reusable fixtures Key concepts explained in detail: The “Director and Actor” analogy to understand page objects & fixtures How InstanceType T ensures correct typing for page objects Why super(page) helps with BasePage inheritance How to pass Page Object classes dynamically into fixtures Clean imports with an index.ts export pattern Why this is important: For large automation projects, repetitive fixture setup can slow you down. By using a generic helper like createTestFunction, you can onboard new page objects instantly without copy-pasting fixture code—saving time and avoiding maintenance headaches. 📌 Technologies used: Playwright Test Runner Playwright-BDD TypeScript Page Object Model (POM) Fixtures & Generics in TypeScript Barrel exports (index.ts) 🎥 Watch now to learn how to make your Playwright BDD setup cleaner, faster, and more maintainable! #Playwright #BDD #TypeScript #TestAutomation #QA #AutomationTesting #Fixtures #PageObjectModel #Generics #PlaywrightBDD #BoilerplateReduction #ReusableCode
