Agile Testers are often known as Quality Analysts (QA), Software Engineers in Test, Test Engineers and QA Leads, among other variances. I've been working as an Agile QA for a while and I would like to share my point of view about how QAs work in an agile team. In this article, I will use the term QA to represent an "Agile Tester". Most people, even in agile teams, treat QAs as a sub-role or a separate role in the team. I believe this is an outdated conception. The difference between a QA and a Dev lies in the mindset.
