AGENDA:

**QA in the Multiverse: One Product, Infinite Variants** (EN)
Jan Skála

Abstract:
We’ll explore how Pricefx QA ensures reliability across countless customer configurations—each like its own “reality.” We’ll show how quality defines product as much as features or design, and how that principle drives our journey toward continuous delivery, where change is constant and quality must be immediate.

Jan Skála is Lead QA Engineer at Pricefx

**I Loved Snapshots in 2016. A Decade Later, Let's Revisit** (EN)
Robin Pokorný

Abstract:
In 2016, snapshot testing felt revolutionary. I promoted it everywhere. Then came the backlash: fragile tests, large snapshots, and mindless change approval. The community wasn't amazed. Yet in 2024, Node.js added native snapshot support. Why?

This talk traces snapshot testing's turbulent decade: from Facebook's game-changing release to general rejection, and examines what we got right, what we got wrong, and what place snapshots have today. Spoiler: the story isn't as simple as “snapshots bad”. Let's revisit with clearer eyes.

Robin is a Sr. Staff Engineer at Ataccama based in Berlin. He started with CSS during the Responsive revolution, moved to React just when it dropped, and now designs evolvable domain-driven systems. Robin organises several meetups: he’s the co-founder of Frontendisti.cz, runs React Berlin and most recently Software Design Berlin.
