Manual Scenarios

You build a manual scenario by selecting scripts to run, assigning load generators on which to run the scripts, and distributing Vusers to run among the scripts.

You can design a manual scenario in one of the following modes:

• Vuser group mode. In this mode, each script you select for the scenario is assigned to a Vuser group. You assign a number of Vusers to each Vuser group that you create. You can instruct all Vusers in a group to run the same script on the same load generator, or you can assign different scripts and load generators to the various Vusers in a group.
• Percentage mode. In this mode, you define a total number of Vusers to be used in the scenario, and assign load generators and a percentage of the total number of Vusers to each script.

After you define which Vuser groups/scripts to run in the scenario, you select or build a schedule by which to run the scenario. For more information, see Scheduling Manual Scenarios.

You can also create Service Level Agreements (SLAs) which are specific goals that you define for your load test scenario. When you run the scenario, LoadRunner gathers and stores performance-related data. When you analyze the run, Analysis compares this data against the SLAs and determines SLA statuses for the defined measurements. For more information, see Service Level Agreements.

Changing Scenario Modes

You can convert a scenario from the Vuser group mode to the percentage mode and vice versa.

The following table describes what happens to the scenario when converting from the one mode to the other:

Vuser group mode to percentage mode

If a Vuser group contains multiple scripts, in percentage mode the scripts are listed one by one in the Scenario Scripts pane. In the percentage mode, all load generators are assigned to all Vuser scripts by default. If multiple load generators are assigned to a Vuser group, the Vusers assigned to the scripts in the percentage mode are distributed evenly among the load generators originally assigned to the group. If you defined group schedules for the Vuser groups, these settings will be lost. All profiles will contain schedule by scenario settings only. For details about scheduling scenarios, see Scheduling Manual Scenarios.

Percentage mode to Vuser group mode

Each script is converted to a Vuser group. If you defined multiple load generators for a Vuser script, the Vuser group that is created when converting the scenario will also contain multiple load generators.
