For a while, I had a few collections of API tests in Postman while I was exploring our API a while ago. We aren't planning to use Postman for API automation and I thought what if I speed up API test automation by giving my agent json specs (claude-4-sonnet in Cursor) and ask to convert those specs into API tests.
Beforehand, I have asked agent to read and run already existing API tests and asked it to follow the pattern, coding standards that are already established in the repo. In this way, I can keep consistency and should take less time to review vibed tests to align with existing.
What I have realised is I didn't ask my agent to not generate tests for endpoints that already exist, so I will need to review those to make sure there aren't duplicates. Something to keep in mind for next time.
