Combinatorial Testing Skill: Cover interacting factors without multiplying every possibility
Combinatorial Testing field guide: select factor levels, pair or t-way coverage, constraints, risks, and evidence.
#QA Skills
Pairwise Testing Skill: Cover the interactions most likely to expose a defect
Pairwise Testing field guide: select factor values, constraints, pair coverage, risk weighting, and uncovered interactions.
Decision Table Testing Skill: Expose rule combinations before they become production exceptions
Decision Table Testing field guide: model conditions, actions, impossible combinations, priorities, and expected outcomes.
State Transition Testing Skill: Derive Reachable and Abnormal Paths from Real Rules
A bilingual guide to deriving traceable state-transition test candidates from states, events, guards, actions, and persistence evidence.
Boundary Value Testing Skill: Make the edge of a rule explicit before the data crosses it
Boundary Value Testing field guide: select lower, upper, adjacent, invalid, and transition values from explicit rules.
Equivalence Partitioning Skill: Reduce input space without losing the rule that matters
Equivalence Partitioning field guide: divide valid, invalid, empty, boundary, and conditional input classes with traceable representatives.
Edge Case Discovery Skill: Find the awkward states a happy-path requirement leaves behind
Edge Case Discovery field guide: explore unusual data, timing, identity, state, environment, and recovery conditions with evidence.
Negative Scenario Discovery Skill: Find the failure paths the happy journey carefully avoids
Negative Scenario Discovery field guide: identify rejection, interruption, misuse, invalid state, dependency, and recovery scenarios.
Risk-Based Testing Skill: Turn Risk Evidence into Test Depth and Scope
A bilingual guide to turning supplied quality risks, failure modes, and delivery constraints into prioritized test objectives, methods, depth, and trade-offs.
Test Scope Analysis Skill: Make Inclusion, Exclusion, and Expansion Boundaries Explicit
A bilingual guide to defining test scope, depth, dependencies, stop conditions, expansion triggers, and residual risk before execution.
Business Rule Extraction Skill: Turn policy prose into rules a team can actually verify
Business Rule Extraction field guide: identify actors, conditions, decisions, exceptions, states, and evidence from business material.
Requirement Traceability Analysis Skill: Build a Bidirectional Evidence Trail
A bilingual guide to mapping requirements, design, code, tests, defects, and validation evidence without confusing links with coverage.
