Review AI-Generated Code With Tests and Evidence
Use the same code-review discipline for AI output that you expect from a teammate: tests, diffs, edge cases, and security checks.
Learning objectives
- Review a generated diff for behavior and scope
- Add tests that prove the requested change
- Identify security-sensitive output before merge

Try one bounded workflow.
Review
Keep evidence, revise, and share.
Generated code is still a proposed diff
Review AI output line by line when it touches authentication, authorization, money, personal data, network access, or destructive actions. Start with scope: did it edit only the requested surface? Then inspect behavior, error paths, validation, dependencies, and operational impact.
Let tests state the promise
Tests should prove what the user asked for, not merely repeat implementation details. Add normal, boundary, invalid, and regression cases. Run type checks, linting, and focused tests before broader suites. If the change cannot be tested, document why and ask whether the design can become more observable.
Practice: review a small patch
Take a generated utility function. Write a test matrix first, then compare it against the function. Check empty input, unexpected types, malformed data, and large input. Ask whether a simpler implementation would make the contract clearer.
Common mistake
Do not accept an explanation as evidence. A confident description of what code does is not a substitute for executing tests, reading the diff, or checking the real integration boundary.
