Solution
Match standard software testing techniques with their appropriate testing levels and methodologies.
Definitions:
- (P) Condition coverage: A structural metric that checks whether each Boolean sub-expression evaluates to both true and false. This is a white-box testing technique (iii).
- (Q) Equivalence class partitioning: Divides the input domain into valid and invalid partitions to select representative test cases without inspecting code. This is a black-box testing technique (i).
- (R) Volume testing: Subjects the system to large amounts of data to evaluate its performance and stability under heavy loads. This is a performance testing technique (iv).
- (S) Alpha testing: Conducted at the developer site by potential end-users or an independent test team prior to release. This is a form of system / acceptance testing (ii).
Aligning:
P-iii, Q-i, R-iv, S-ii (option C).
Final answer
C
Common trap
Classifying equivalence class partitioning under white-box testing rather than specification-based black-box testing.
The answer is the one in the official GATE answer key. The solution is this site's own explanation.
