A mock server in Ruby
After the initial release of the mock server many months ago, I have now a stable version available for open use, with improved documentation and some test coverage. The server makes it easy to set up mock data for ReST endpoints to aid the testing of client applications (API consumers). Set up mock once and use across multiple clients that may have been implemented in different codebases and technologies. Can be used for both manual and automation testing. The server is based on Sinatra and backed by sqlite. https://github.com/mvemjsun/mock_server
