As a result, we made the call to move the entire program over to a Mountebank OSS-based solution with a custom provision to give us the ability to expand/shrink our mocking needs on demand. mountebank is the first open source tool to provide cross-platform, multi-protocol test doubles over the wire. Just point your application to mountebank instead of the real dependency, and test like you would with traditional stubs and mocks.
