For detecting interface errors, the text suggests that inspections can sometimes be better than testing. In what way are inspections particularly effective for interface testing?

Inspections can execute the components faster than automated test suites

Inspections can concentrate on component interfaces and ask questions about assumed interface behavior

Inspections can automatically generate all possible parameter combinations

Inspections are required by most software quality standards before interface testing

Correct Answer

Inspections can concentrate on component interfaces and ask questions about assumed interface behavior

Explanation

Inspections can be better than testing for detecting some interface errors because they can concentrate specifically on component interfaces and critically question the assumptions made about interface behavior. During an inspection session, reviewers can ask 'what does this component assume about the called component?' - a question that is difficult to address systematically through testing alone.
