Design Testing Strategy A reference manual for designing a fit-for-purpose, fit-for-criticality testing strategy. This skill is decision-oriented , not philosophical: every gate is deterministic (ON when X / OFF when Y), every schema is enforced (field ordering matters), every example is worked end-to-end. How To Use This Skill 1. Read Decision Gates in order (Gate 0 - Gate 6). Each gate is independent — you may finish with any subset of test types ON. 2. Apply Strategic Skip Heuristics to remove ON gates that would yield low ROI for this artifact. 3. For each ON gate, fill the Test Matrix Sc…
