問題文
A bank has to re-run a large regression suite after every change to its payment functions, and it also has to be able to show an auditor that the compliance-critical functions were exercised before each release. Which benefit of test automation addresses both needs at once?
選択肢
- Hiring the specialist testers widens the available skills and produces the deeper insight.
- Buying the commercial toolset removes the manual effort and produces the instant gain.
- Copying the production records improves the input realism and produces the exact reproduction.
- Running the repeatable scripts shortens the regression cycle and produces the auditable evidence.
