NockHTTP server mocking for Node.js

Test HTTP clients in isolation with precise request matching and predictable replies.

Match requests precisely
Match hosts, paths, query strings, request bodies, and headers with strings, regular expressions, or functions.
Control responses
Define status codes, bodies, headers, errors, streams, and response delays for each intercepted request.
Verify expected traffic
Assert that requests happened, inspect pending mocks, and prevent unwanted real network connections.
