A network-based testing method and service integrated with a tool that publishes one or more tagged test cases with tags being executable to reproduce a sequence of events for a system under test, SUT, caused by an original test case. The method is performed in a network and is intended for testing software or hardware by first creating an original test case for a system under test, SUT, and performing a sequence of events for the original test case for testing it. The tested case is stored and information of the performed sequence of events is tagged to the tested case. The tagged test case is then sent to a service that publishes tagged test cases. The service publishes the tagged case in a way to be reproduced via the service.
