A surprisingly large number of different types of testing exist and are used during the development and operation of software-reliant systems. We have identified nearly 200 of these general types of testing and there are many additional types that are application-domain specific. 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.
One way to understand so many types of testing is to classify them into a taxonomy that groups similar testing types together. One way to organize them is by the types of questions they answer. Specifically, types of testing can be categorized by the five Ws and two Hs: what, when, why, who, where, how, and how well.
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. Whereas not all of these testing types are
relevant on all projects, a complete taxonomy can be very used to help
discover the ones that are appropriate and ensure than no relevant type
of testing is accidentally overlooked. Such a taxonomy can also be
useful as a way to organize and prioritize one's study of testing.
This webinar introduces the attendee to our taxonomy of testing types,
thereby clarifying the grand scope of testing and enabling the attendee
to better select the appropriate types of testing to for their specific
