Equivalence Partitioning & Boundary Value Analysis

Equivalence partitioning and boundary value analysis are two of the oldest and most effective black-box test design techniques. They are taught in every software testing curriculum, appear on every certification exam, and yet are frequently applied mechanically without real understanding — resulting in test suites that look thorough but miss

Pairwise & Combinatorial Testing: Covering Edge Cases Efficiently

Testing every possible combination of input parameters is mathematically straightforward and practically impossible. A feature with 10 parameters, each taking 5 values, has 5¹⁰ = nearly 10 million combinations. No team tests that. But most bugs are not caused by exotic 10-way interactions — they are caused by pairs or triples
