Abstract
A method, system, and computer program product for estimating propagation time for an injected fault are configured to: determine normal execution times of respective services in a call graph of an application; determine normal execution times of respective network communications between ones of the services; determine faulty execution times of respective ones of the services; and generate a propagation time for a particular type of fault injected at a particular fault injection location in the call graph based on the determined normal execution times of respective services, the determined normal execution times of respective network communications, and the determined faulty execution times of respective ones of the services.
