As part of the Keploy API Fellowship, the author explored API testing by using the Keploy Chrome Extension's 'Record Calls' feature.
The author tested API calls on Chess.com and Keploy.io, letting Keploy automatically capture the requests/responses and export them as cURL commands for replay and debugging.
The author found it surprising that they didn't have to write tests manually, could see how many calls were captured, and could easily export tests for use with tools like curl or shell scripts to understand site communication.
The Keploy Extension is highlighted as being better than manual testing for beginners due to its ease of setup, auto-generated test writing, and one-click export for replaying calls.
