Topic: Introduction-to-Loadrunner-Part-5

Objectives of this article to explain LoadRunner runtime settings, controller, the different types of scenarios,  How to create manual scenario.

Run-Time Settings

• Control the behavior of the user when running the script
• Configure Web Vusers to emulate real users accessing the Web site
  

Important Run-Time Settings

•   Browser Emulation
•   Think Time
•   Logs

Browser Emulation

•   Specify Browser type
•   Simulate cache
•   Emulate network capacity
•   Emulate modem speed

 

Think Time Settings

•   Specified in seconds
•   Ignore recorded think time
•   Replay the recorded think time
•   Randomize think time
•   Multiply the recorded think time by specific values
•   Limit the think time to a maximum value

Log Settings

•  Can disable logging
•  Log a specific set of function calls and messages – Standard Log
•  Log parameter substitutions
•  Log response data from server
•  All the messages and  function calls raised

Controller

What is a Scenario?

•   It describes the events that occur during a testing session
•   It is the means by which you emulate a real-life user
•   Scenarios include

1.      a list of machines on which Vusers run
2.      a list of scripts that the Vusers run
3.      a specified number of Vusers or
4.      Vuser groups that run during the scenario

•   Scenarios are created using the LoadRunner Controller 

Types of Scenario

• Manual Scenario
  

Create a scenario by defining Vuser groups to which are assigned a quantity of individual Vusers, Vuser scripts, and load generators to run the scripts.

• Goal Oriented Scenario
  

For Web tests, the goals of the tests are defined by us and LoadRunner automatically builds a scenario based on these goals.

Manual Scenario

Creating a Manual Scenario

•   Create Vuser groups 
•   Each script selected in the New Scenario dialog box is assigned to a Vuser group
•   Each Vuser group is assigned a number of virtual users
•   All Vusers in a group can be assigned to run the same script on the same load generator machine
  OR
•   Different scripts and load generators can be assigned to the various Vusers in a group
