Comparison of API simulation tools
The tools listed here support emulating[1] or simulating APIs and software systems. They are also called[2] API mocking tools, service virtualization tools, over the wire test doubles and tools for stubbing and mocking HTTP(S) and other protocols.[1] They enable component testing in isolation.[3]
