While tools like Jasmine, Karma, and Jest were always there when we needed them, it’s time to move on.
In this talk, we’ll revisit the battle scars they left behind — like the hours spent forcing things to just work with the tests — and explore how tools like Vitest aren’t just trendier. They’re the result of hard-earned lessons in speed, reliability, and developer experience.
You’ll leave with:
A sense of closure for the old stack.
A tour of the modern features Vitest brings to the table.
A migration path to Vitest.
Concrete patterns that future-proof your Angular tests.
Come for the nostalgia. Stay for the clarity.

When we write code, we often prioritize completing our feature over performance. However, performance may become a bottleneck, requiring additional resources and time. When we reach that point, how should we proceed?
In this session, we will explore tools that can help us identify performance problems and focus our code improvements in the most beneficial areas. Some of these tools include AsyncProfiler, JMH, JFR, and others. Expect a session with lots of demos, live coding, real-life examples, and tips and tricks to help you get started on improving your code’s performance.")
