"There were much more than 3 learned points. 1. SonarQube. This is a free tool that can scan your code and provide reports regarding: unit test coverage, code smells, security vulnerabilities. I've already found a good tutorial and playing with this tool right now. 2. Principles that I have to learn to be a good automation test engineer: - SOLID, - OOP, - types of classes, - programming design patterns and their realization for a programming language I'm using, - Composition over Inheritance, - DRY vs WeEnjoyTyping. 3. Denys has strongly recommended to read Leading Quality book to be able to build successful QA strategies and push (sell) my ideas to a higher management level. The book is already purchased and delivered. I'm finishing another book to start reading this new one."
