Welcome to the 236th edition of Coding Jag brought to you by LambdaTest!👐
Running tests sequentially might seem logical, but it’s a trap! ⚠️ Slow execution, flaky tests, and hidden dependencies can make debugging a nightmare. So, what’s the smarter alternative? 🚨 Nočnica Mellifera dives into why parallelism is the key to scalable, efficient tests!
Beyond test execution strategies, this edition explores software quality beyond bug-finding, domain-driven test design, and AI’s growing role in automation. Brijesh Deb challenges the term manual testing, urging testers to focus on value and strategy rather than outdated labels.
Learn how Zalando built a blazingly fast API, mastered Cypress and Playwright, and uncovered the latest trends in front-end development. Plus, get hands-on with AI-driven testing strategies, debugging insights, and expert tips to advance your testing career. 🚀
Let’s rethink how you test!
