What senior test engineers actually need to know.

A practitioner's guide distilled from 20+ years of quality engineering at Apple, Netflix, PayPal, and eBay — 18 chapters and 80+ real-world code examples covering the full modern SDET stack in one book: TypeScript foundations, Playwright patterns at scale (fixtures, API mocking, sharding), one Appium test case driving both native iOS and Android, schema-validated API testing with and without an OpenAPI spec, Karate vs. REST Assured vs. Playwright compared with judgment, performance testing end to end (JMeter, K6, and RUM), the Screenplay pattern, device and wearable testing, and AI-assisted UI automation and QA.

Includes the complete, tested companion code.

After purchase, readers receive access to the book's companion Git repositories — a production-grade Python + Appium mobile framework (one test, both iOS and Android) and a Playwright + TypeScript Screenplay-pattern suite — both verified on the Sauce Labs cloud platform with real devices. Fulfilled by email via support@aitestguru.com within 48 hours of purchase.
