Given below are two statements, one is labelled as Assertion A and the other is labelled as

Reason R

Assertion A : Software developers donot do exhaustive software testing in practice.

Reason R : Even for small inputs, exhaustive testing is too computationally intensive (e.g., takes too long) to run all the tests. In light of the above statements, choose the correct answer from the options given below

1. ABoth A and R are true and R is the correct explanation of A
2. BBoth A and R are true but R is NOT the correct explanation of A
3. CA is true but R is false
4. DA is false but R is true

Pick an option to check yourself, or open the answer below.

Show answer & explanation

Correct answer: A. Both A and R are true and R is the correct explanation of A

Explanation

Exhaustive testing is not done because even small input spaces produce too many test cases to run; R explains A.
