A Taxonomy of Testing Types
Software Engineering Institute
A surprisingly large number of different types of testing exist and are used during the development and operation of software-reliant systems. While most testers, test managers, and other testing stakeholders are quite knowledgeable about a relatively small number of testing types, many people know very little about most of them and are unaware that others even exist.
Understanding these different types of testing is important because different types of testing tend to uncover different types of defects and multiple testing types are needed to achieve sufficiently low levels of residual defects. Although not all of these testing types are relevant on all projects, a complete taxonomy can be used to help discover the ones that are appropriate and ensure that no relevant types of testing are accidentally overlooked. Such a taxonomy can also be useful as a way to organize and prioritize one’s study of testing.
In this podcast, Donald Firesmith introduces the taxonomy of testing types he created to help testers and testing stakeholders select the appropriate types of testing for their specific needs.
