Software Testing Techniques

Testing techniques are systematic methods for deriving test cases from requirements, specifications, or code. They replace guesswork with structured analysis, ensuring that tests cover the most important scenarios efficiently.

◈Key Points

Black-box techniques: Equivalence Partitioning, Boundary Value Analysis, Decision Table, State Transition, Use Case.
White-box techniques: Statement Coverage, Branch Coverage, Path Coverage, Condition Coverage.
Experience-based: Exploratory Testing, Error Guessing, Checklist-based.
Combining multiple techniques gives the best coverage — no single technique is sufficient alone.
Technique selection should be driven by the nature of the system and the type of risk being mitigated.

⚡ Expert Pro Tip

For any feature, apply at least two complementary techniques: one structured (e.g., equivalence partitioning) and one exploratory. Structure finds known unknowns; exploration finds unknown unknowns.
