This document discusses the career journey of a QA engineer who has transitioned through various QA roles over 14 years. It poses a series of questions about the tester's experiences with manual and automation testing, challenges in the QA field, different software development lifecycles (SDLCs), and their experiences adopting behavior-driven development (BDD). The QA engineer offers to demonstrate a sample BDD project using Cucumber, Selenium, and the Serenity framework to illustrate how BDD differs from traditional SDLC models and discuss best practices.
