Beyond Unit Tests: Modern Testing in Angular

You don’t see the need for tests? You don’t trust them? Your tests almost never revealed a bug? Sounds like you’re doing too much unit testing. In this video, we rethink traditional testing strategies and explore how to bring back the joy of testing. Starting with a breakdown of unit, component, integration, and E2E tests, I’ll demonstrate why integration tests often outperform unit tests regarding coverage and confidence. We’ll also challenge the outdated testing pyramid and introduce the Testing Trophy as a smarter alternative. Finally, the video features a collection of clips from the Angular Q&A session with Jeremy Elbourn, highlighting his key takeaways and reinforcing the importance of focusing on impactful tests that bring real value. 💬 Testing discussions can get opinionated and emotional, and that’s okay! Don’t hesitate to ask questions or share your opinions—let’s keep the conversation productive and insightful.
