A presentation at React Open Source Berlin in in Berlin, Germany by Robin Pokorny

With the rapid release of speed improvements, it’s easy to miss a new useful feature. I will present some lesser-known possibilities of recent Jest versions I’ve learned during experimenting, reading (and writing) the docs, and browsing the code.
