Once upon a time​

At the very early stage of my career I joined enterprise and knew - something is moving me, it's not me swimming there. Buttons, CRUDs, a lot of "let's jump into a call".

On this page, I want to cover the caveats I encountered while shaping my approach to unit testing in the context of observability.
