Probably these areas are more specific to a certain domain and belong in the knowledgeandskill set ofa T-shaped tester in thatdomain. Finally, it is also interesting to see that ISTQB also considers test automation andmobileapplication testing to bespecialist areaswithin testing. Today, theseare almost like standard requirements for a tester. The fact that these were originally defined as specialist areas by ISTQB perhaps shows how quickly the market changes. What is defined as a specialist area today could well be a common requirement for knowledge and skills tomorrow. This also points out the danger of being an I-shaped test specialist. Today, there is a huge demand for security test specialists and perhaps slightly less for performance test specialists. However, this may rapidly change or the specialism gradually moves to become a generalized knowledge and skill area that is required for T-shaped testers. Usability testing is probablysomewhere in that transition.

Sometimes is it possible to hop from one test specialism to a new one when the current one becomes obsolete. At the same time, is doesn’t hurt to also have some knowledge and skills that typically belong to the T-shaped tester as a fallback scenario.The latterwill alsobebeneficialwhenworkingless stand-aloneandbeing
