The Tester’s Pocketbook proposes a set of Test Axioms that provide a framework for all testing. But there is no single agreed definition of test. This is mostly because every consultant and author has tended to write their own definition to suit their own purposes (and I am as guilty as the rest of them). As an industry, we are hamstrung because of this. Our clients are confused, and we get distracted by discussions on definitions because of not-invented-here mentalities and our competitive instincts.

These pages provide context-neutral definitions of the key terms used in the Test Axioms.
