Which is a recognised principle of software testing?
AExhaustive testing of every input is feasible
BTesting shows presence, not absence, of defects
CSufficient testing guarantees defect-free software
DTest independence reduces test result quality
Answer & Solution
Correct answer: B. Testing shows presence, not absence, of defects
ISTQB principle 2: 'Testing shows the presence of defects, but cannot prove that there are no defects.' Exhaustive testing is impossible; testing reduces but does not eliminate risk.
