TypeScript and Playwright for QA

Start with no coding experience. Learn TypeScript through browser exercises, then build an npm Playwright project against a deterministic local application.

What you’ll be able to do.

01

Write strict TypeScript that represents test data and decisions

02

Build isolated Playwright tests with resilient locators and web assertions

03

Diagnose failures with traces, reports, and controlled network behavior

04

Run type checks and browser tests through npm and continuous integration

Curriculum

10 focused modules.
