US Patent 11693750 Virtual device for providing test data

A virtual device acquires a transaction history between a legacy computing device and a linked device; obtains a first request provided from the legacy computing device based on the transaction history and a first response received from the linked device in response to the first request; receives a second request corresponding to the first request from a new computing device and determines a second response to the second request; and provides test information for the new computing device based on a comparison of the first response and the second response.
