Use the Feed Simulation Editor to create a new feed simulation file with
.sbfs extension, or to edit an existing one.
The Feed Simulation Editor is not open by default in the SB Test/Debug perspective. The view opens when you invoke commands to edit a new feed simulation, or when you double-click the name of a feed simulation file in the Feed Simulations View.
See Using the Feed Simulation Editor to learn how to use the fields in this view.
