Patent number: 11775417Abstract: A service testing system is disclosed to enable consistent replay of stateful requests on a service whose output depends on the service's execution state prior to the requests. In embodiments, the service implements a compute engine that executes service requests and a storage subsystem that maintains execution states during the execution of stateful requests. When a stateful request is received during testing, the storage subsystem creates an in-memory test copy of the execution state to support execution of the request, and provides the test copy to the compute engine. In embodiments, the storage subsystem will create a separate instance of execution state for each individual test run. The disclosed techniques enable mock execution states to be easily created for testing of stateful requests, in a manner that is transparent to the compute engine and does not impact production execution data maintained by the service.Type: GrantFiled: May 18, 2020Date of Patent: October 3, 2023Assignee: Amazon Technologies, Inc.Inventors: Abhishek Arora, Onkar Walavalkar, Aman Gupta, Xuetao Fan, Kurtis Robert Kuszmaul, Christopher Chandler
