Abstract: There are provided systems and methods for simulation computing services for testing application functionalities. During application development and testing a simulation service framework may be widely accessible from a service provider or other online platform that allows an application developer to test application functionalities in different environments and based on different runtime conditions. The framework may implement one or more simulation services that are generated and provided to simulate data service calls, responses, and data processing results that may be performed when an application interacts with a real online service (e.g., database, other application, or other online service that provides some data and/or data processing to an application). Application code in the application's dependencies may be changes to perform the call to the simulation service. This service may then return some result that is expected based on the service's simulated data.
