Testing route handlers with supertest
Running your Express (or similar) HTTP handlers in-process and asserting responses without a real network.
"I want to ensure my API returns the right status and JSON without starting a server or hitting the network."
Supertest lets you mount your app in the test process and send HTTP requests to its routes, so you can assert status codes, headers, and body content quickly and deterministically.
