Using LoadRunner
Using LoadRunner, you divide your client/server performance testing requirements
into
scenarios
. A scenario defines the events that occur during each testing
session. Thus, for example, a scenario defines and controls the number of users to
emulate, the actions that they perform, and the machines on which they run their
emulations.
In the scenario, LoadRunner replaces human users with
virtual users
or
Vusers
.
When you run a scenario, Vusers emulate the actions of human users--submitting
input to the server. While a workstation accommodates only a single human user,
many Vusers can run concurrently on a single workstation. In fact, a scenario can
contain tens, hundreds, or even thousands of Vusers.
To emulate conditions of heavy user load, you create a large number of Vusers that
perform a series of tasks. For example, you can observe how a server behaves
when one hundred Vusers simultaneously withdraw cash from the bank ATMs. To
accomplish this, you create 100 Vusers, and each Vuser:
1
enters an account number into an ATM
2
enters the amount of cash to withdraw
3
withdraws cash from the account
4
checks the balance of the account
5
repeats the process numerous times
