“Schools of Testing”: Useful Paradigm or Negative Influence? Are there really four different “schools of testing”? Do you have to belong to one? Or are there just different testing strategies, to be selected and blended as appropriate? Has the concept of “schools of testing” promoted clearer thinking about testing, or has this concept actually created a useless schism, sowing conflict and slowing growth of the profession? In this debate, Rex Black argued the negative side of the case, being one of the leading critics of the concept of “schools of testing.” One the other side, you’ll hear one of the originators of the concept, Cem Kaner, argue for its benefits. Love it or hate it, you can hear both sides and make up your own mind.
