## Description

How to start test automation from scratch - the legacy system example.
How to make test automation matter - esp. when everything is always not enough - developer experience, SSDLC experience.

The importance of test pyramid, and why sometimes unittests are useless, and sometimes they are not.
Basic truths why are we still forgetting about them - the context of 20yo product and replatforming and technology debt
How much is enough - the core banking system - 3k, 4k, 5k or more?

We really did magic - it can be yours.
