Practice the black-box, white-box, and experience-based techniques used to derive effective test coverage.
Written and reviewed by ShiftQA Labs QA Education Team · Updated September 2, 2026
Equivalence partitioning groups values expected to behave alike. Boundary value analysis targets edges where defects cluster. Decision tables cover combinations of conditions and actions. State transition testing covers events, states, and valid or invalid transitions.
Statement testing exercises executable statements. Branch testing exercises the outcomes of decision points and also subsumes statement coverage. Coverage measures what structure was exercised; it does not prove that assertions were strong or requirements complete.
Error guessing uses knowledge of common defects and failure history. Exploratory testing combines learning, design, and execution. Checklist-based testing uses reusable prompts. These techniques complement systematic models and are valuable when specifications are limited.
