We had an old Node.js service, no tests, nobody on the team wrote it. Tried writing tests manually for two weeks and gave up. Too many moving parts to mock by hand. Keploy attached to it with no code changes; we ran real traffic through for a couple of days, and came out with over 130 tests. Actually reflecting how the service behaves, not how we guessed it did.

One of the things I appreciate most about Keploy is how it prioritizes the developer experience. Instead of relying on manual test creation, it captures actual API interactions to generate meaningful test cases automatically, making the testing process far more efficient and seamless. I’m also drawn to its collaborative open-source community and its strong focus on engineering excellence.
