Salesforce QA, written after the bugs. Not before.
Case studies and frameworks from real projects. Short sentences. Own mistakes. No theory.

Field Notes
Three Weeks, Three Failure Classes
Step discount failed three weeks running and the failure class changed every week, because each retest was scoped to whatever the previous week's bugs had named.

Field Notes
Four Candidate Keys for One Lookup
Four candidate keys were circulating for one lookup — postcode, Service_ID, S-Number and UPRN. The real defect was that the chosen key was one level coarser than the fact it encodes.
