7.1🔒The Combinatorial Explosion ProblemMultiple input parameters create exponential combinations. A 5-parameter form with 3-5 values each produces hundreds of combinations…35 words

7.2🔒Pairwise TestingResearch shows 70-90% of defects are triggered by interactions between at most 2 parameters (NIST). Pairwise testing covers all 2-way…53 words

7.3🔒The AI + PICT Hybrid WorkflowFor maximum rigor:40 words

7.4🔒Guidelines- 2-3 params: Test all combinations manually - 4-7 params: Pairwise with AI is the sweet spot - 8-15 params: Use PICT or ACTS - 15+ params…31 words

7.5🔒Q&ASelf-Assessment Quiz1. What is the key insight behind pairwise testing? 2. When should you use 3-way instead of pairwise? 3. How do you verify pairwise…56 words

7.6🔒Key Takeaways- Combinatorial testing bridges "test everything" and "test randomly" - Pairwise catches 70-90% of defects with 95%+ test reduction…35 words
