You completed your code change. You call your API from your client. Success! Set it free to the world (or at least your dev team)!

Does your code cover all the requirements? Did it break another endpoint? What if someone sets id = -100000?

Not only can do Test-Driven Development (TDD) against your API, can you afford not to?

By ANGRY (negative versus happy path) testing your code, you can spend less time in development, more time on new projects and less on maintenance, and reduce the risk of bugs (especially in production).

Using a simple, powerful, and widely-adopted tool like Postman, you can share test collections with your team and build meaningful code coverage of your API.
