Specialties within Testing
A tour of the different testing specialties: focus, skills and value of each role so you can choose your path.
In testing there are many titles: manual tester, QA, QE, QAE… But what really sets professionals apart are their specialties: focus, skills and value. Beyond the title, what matters is the value you bring.
The specialties
