Define the primary purpose of testing as gathering information about the state of the system to enable informed decisions. This reframes testing from a simple bug-finding exercise to a strategic activity that reduces uncertainty. Every test must be justified by the value of the information it provides.
Example
Before adding a new automated test, we ask, “What new information will this provide that our existing tests do not?“ If the information is redundant or of low value, we reconsider the effort.
