1. A computer program product comprising a computer storage medium embodying computer usable program code for simulating a target service in a development environment, the computer program product comprising: computer usable program code for receiving a service request for a target service in a proxy service executing in memory by a processor of a computer; computer usable program code for determining whether a mode for the proxy service is selected to be either a normal mode, a record mode or an emulate mode; computer usable program code for delegating the service request to the target service through the proxy service if in the normal mode, to a recorder service wrapping the target service and configured to record interactions with the target service if in the record mode, and computer usable program code for retrieving the corresponding interaction data from interaction store and replaying the recorded interactions with the target service previously recorded while in the record mode, and computer usable program code for emulating the functionality of the target service in emulator service instead of delegating the service request to the target service.
