“Essential Mathematics for Testers”
summary
Argues that basic set algebra and boolean tables make test design faster and more reliable by turning vague rules into concrete combinations and outcomes. Uses Cartesian product to enumerate combinations (example: payment methods × banks × countries) and set operations to build equivalence classes for reduction. Uses truth table logic to expose contradictory configurator rules (e.g., feature enabled when X and Y but disabled when X or Y) and to map expected outcomes for each input combination.
