Modern JavaScript Testing: Integration, Contract Testing & AI Tools - JSJ 692

In this episode of JavaScript Jabber, I sit down with Dan Shapir and our special guest, Yoni Goldberg, to dive deep into the ever-evolving world of JavaScript testing. Yoni, a consultant who’s worked with over 40 organizations to refine developer workflows, shares valuable lessons learned from helping teams design efficient and reliable tests.

We explore emerging trends in testing, including the rise of browser-based test runners, the shift from unit testing toward more integration and component testing, and how modern frameworks like Playwright, Vite Test Browser Mode, and Storybook are changing the way developers think about confidence in their code. We also tackle the role of AI in writing and maintaining tests, the pros and cons of mocking vs. real backends, and why contract testing is becoming essential in 2025.

If you’ve ever struggled with flaky end-to-end tests, wondered how to balance speed with confidence, or wanted a clear breakdown of modern testing tools, this conversation will give you practical insights and fresh perspectives to take back to your projects.
