MockServer

aid: mockserver
name: MockServer
description: MockServer enables easy mocking of any system you integrate with via HTTP or HTTPS (e.g. services, web sites,
  etc) with clients in Java, JavaScript, and Ruby and a simple REST API. MockServer can be used to mock APIs that are not
  yet fully developed, isolate the system under test for reliable testing, simulate slow or faulty endpoints, and record/replay
  requests.
