Testing in agile, addresses the processes that produce software and also products of those processes. Hence I ask my teams to not just focus on validating software after development, but also check processes that produce software like, quality of stories, requirement/impact analysis, acceptance criteria(using behavior-driven-development to address “3 amigos problem), and more.
Take a look at our agile testing workshop which is a detailed 2 day course which focusses on test automation strategies, lean approach to defect prevention, various tools and techniques to automate, BDD(behavior-driven-development) and how to use various frameworks – Linear Scripting, Test Library Architecture, Data-Driven Testing, Keyword/Table-Driven and Hybrid automation frameworks.
