How Ignorant Are We?


The relationship between the 5 orders of ignorance and software testing is much closer than most people realise.



Testing isn’t just about checking that software conforms to some explicit, known requirements. Testing is also about exploration and investigating the software and our hypotheses in order to discover and uncover new information. This talk will teach about the 5 orders of ignorance regarding information and how these orders very closely relate to testing.



In this talk, I’ll discuss each layer of the 5 orders within the context of testing software and I’ll touch on the key skills and processes that fit within each layer. Information is key! Be prepared to bend your mind and be open to new ways of thinking about testing.
