Another plug-in can contribute options to a schedule, have them persisted in the schedule model, and have a corresponding user interface displayed to edit those options. A schedule object represents a performance testing schedule. It is the main object in the schedule model. Schedules can have only one type of element added to them, a UserGroups object. You can use the com.ibm.rational.test.common.schedule.UserGroup interface to add a user group to a schedule.
The mechanism to extend scheduling is similar to the mechanism used to extend the test editor. See the "Extending the test editor" topic for more information.
