How We Test ATM UIs

In the summer of 2025, Ozon Bank launched its own ATM network. For the team, this was a completely new domain: we had no prior experience testing or automating ATM user interfaces.

This talk explores how modern ATMs work - their main components, UI, and the challenges that arise when testing systems at the intersection of hardware and software.

It also covers our journey toward regression automation for ATM UI: the tools and frameworks we experimented with, the limitations we encountered, and the solution we ultimately adopted.
