Stoping and Restarting a Run

There is no built in option to pause a load test. Depending on how your data source is setup it might be possible for you to create a custom event to do this. You would have to create an event that records the last row used from the datas source. Then you could either manually update the start row in the data source or create a second event to update that for you. You would also need to make sure that the shared option is enabled on the datasource options for load testing. There might be other ways to do this but that was the first thing I could think of.
