Here's my second attempt at a set of testing axioms. I've tried to name and define each with a 'one-liner'. The "Narrative/Action" makes a suggestion, and the "If you don't" suggests what might happen if you ignore the axiom. There are no recommendation as to the practice, process or heuristic you might want to deploy. Most axioms simply suggest you identify/agree/define an approach or appreciate/recognise a situation.
