A lightweight Sinatra application that can be set up as a mock server to respond to API end points which respond to HTTP verbs. No need to program mocks using a language specific implementation for testing. Easy to use user interface to maintain mocks. Just supply a URL along with the HTTP headers and return codes along with the response body to set up a mock response. Can be used for manual testing and automation testing of client applications.
