Even more so than today, these specialists will be full- time test professionals with in-depth knowledge and skills in one specific (non- functional) testing areaonly. The concept of a T-shaped person is of course popular in the Agile world and refers to the need for cross-skilled developers,business analysists and testers in an Agile team,e.g.aScrumteam. Inpractice,manytalkaboutbeingaT-shapedtester, but only a few truly are.
