Question

Match the following: List I List II (P) Condition coverage (i) Black-box testing (Q) Equivalence class partitioning (ii) System testing (R) Volume testing (iii) White-box testing (S) Alpha testing (iv) Performance testing

	List I		List II
(P)	Condition coverage	(i)	Black-box testing
(Q)	Equivalence class partitioning	(ii)	System testing
(R)	Volume testing	(iii)	White-box testing
(S)	Alpha testing	(iv)	Performance testing

Correct answer (C) P-iii, Q-i, R-iv, S-ii Solution Let's analyze and match each item from List I with the appropriate item from List II. (P) Condition coverage: This is a white-box testing technique that checks if each boolean sub-expression in the code has been evaluated to both true and false. Therefore, P matches with (iii) White-box testing . (Q) Equivalence class partitioning: This is a black-box testing technique where the input domain of a program is divided into partitions of equivalent data from which test cases are derived. The focus is on the input/output behavior without knowledge of the internal code structure. Therefore, Q matches with (i) Black-box testing . (R) Volume testing: This is a type of non-functional testing where the system is subjected to a large volume of data to check its performance and behavior under heavy load. This falls under the umbrella of performance testing. Therefore, R matches with (iv) Performance testing . (S) Alpha testing: This is a form of acceptance testing performed by in-house testers at the developer's site before the product is released to external customers. It is a type of system testing. Therefore, S matches with (ii) System testing . The correct matching is: P \to iii Q \to i R \to iv S \to ii This corresponds to the sequence P-iii, Q-i, R-iv, S-ii, which is given in option (C).

Correct answer (C) P-iii, Q-i, R-iv, S-ii Solution Let's analyze and match each item from List I with the appropriate item from List II. (P) Condition coverage: This is a white-box testing technique that checks if each boolean sub-expression in the code has been evaluated to both true and false.

(Q) Equivalence class partitioning: This is a black-box testing technique where the input domain of a program is divided into partitions of equivalent data from which test cases are derived. The focus is on the input/output behavior without knowledge of the internal code structure. Therefore, Q matches with (i) Black-box testing .
