After you create a scenario, you can set the time at which the scenario will begin running. In addition, for a manual scenario, you can set the duration time of the scenario or of the Vuser groups within the scenario. You can also select to gradually run and stop the Vusers within the scenario or within a Vuser group
An important factor in the creation of a scenario is developing a test that accurately portrays user behavior—the types of actions and the timing of those actions, represented by Vuser scripts.
Using the Scenario Start dialog box, you can instruct LoadRunner to begin executing a scenario with a delay. You can specify either the number of minutes you want LoadRunner to wait from the time a Run command is issued, or the specific time at which you want the scenario to begin. Using the Schedule Builder, you can set the timing aspect of a manual scenario, limiting the execution duration of the scenario or of a Vuser group within the scenario. You limit the execution time duration by specifying the number of minutes a scenario or Vuser group should be in the Running status. When the scenario or group reaches its time limitation, it finishes. The schedule you define is visually displayed in the Load Preview graph.
