Fixed and Scalable Virtual Testers

Chapter 10 - Designing Performance Testing Suites

To insert a user group into a suite:

From an open suite, click

Suite > Insert > User Group

Note:

For detailed procedures, see the TestManager Help.

When you add a user group to a suite, you must specify whether the group contains
fixed or scalable virtual testers:

Fixed

Specifies a static number of virtual testers. Enter the maximum number of

virtual testers that you want to be able to run. For example, if you enter 50 virtual
testers, you can run up to 50 virtual testers in the Sales group each time you run a
suite.

Typically, you assign a fixed number of virtual testers to user groups that do not
add a workload. For example, one virtual tester could run a Warmup test script to
open a database for the virtual testers, and another virtual tester could run a
Shutdown test script to restore and close the database.

Scalable

Specifies a dynamic number of virtual testers. Type the percentage of

the workload that the user group represents. For example, the Accounting group
might represent 20 percent of the virtual testers, the Data Entry group might
represent 30 percent of the virtual testers, and the Sales group might represent 50
percent of the virtual testers in the suite. Each time you run a suite, specify the
total number of virtual testers to be run; TestManager distributes the virtual testers
among the scalable user groups according to the percentages you specify.
