Prerequisites

Start here. Node.js, TypeScript, Browser DevTools, and testing fundamentals — everything you need before picking a framework.

Node.js, npm & the Terminal

Install Node.js, understand npm, and get comfortable with the terminal commands every tester needs

TypeScript for Testers

The 20% of TypeScript you actually need to write automation tests — async/await, types, classes, and imports

Browser DevTools for Automation

Use Chrome DevTools to find reliable selectors, understand the DOM, and debug failing tests

Testing Fundamentals

What E2E testing is, how to write tests that actually catch bugs, and the patterns every automation engineer uses

Test Architecture Fundamentals

Why the Page Object pattern exists, framework-agnostically — before you see it implemented in Playwright, Cypress, or WebdriverIO
