Systems and methods for shadow testing are provided. A new service may be brought online that corresponds to an existing service. The new service may be designated for shadow testing. A call may be received for the existing service from a calling device. The received call may be provided to the existing service, while an asynchronous call corresponding to the received call may be provided to the new service. A result may be received from the existing service in response to the provided call, and a result may be received from the new service in response to the asynchronous call. The result received from the existing service may be used in responding to the received call. Data regarding the result received from the new service may be logged, but the result received from the new service may be excluded from use in responding to the received call. One or more metrics evaluating performance by the new service may be generated.
