Verifying generated code
Run it, read it and test the edges before you trust it.
What you will be able to do
- Run the code and the tests; a plausible snippet is not evidence.
- Check dependencies and method signatures in official docs.
- Review auth, money, personal data and deletion paths twice.
In plain English
Generated code can compile and still be wrong. Check the API against documentation, run the tests, add an edge case and review security-sensitive paths manually. Treat a model’s explanation as a hypothesis, not a proof.
// Do not paste this blindly. Ask:
// 1. What are the inputs and failure paths?
// 2. Is the token read from a secret store?
// 3. What happens on a 429 or timeout?
// 4. Is the response schema validated?
const response = await fetch(url, { headers })
if (!response.ok) throw new Error('Request failed')
return schema.parse(await response.json())Your turn
MediumAdd a failure test
Write a test case for a timeout or non-2xx response before accepting generated fetch code.
