Скачать или смотреть 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/TestRoverAutomatio...
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.
