Performance Testing with LoadRunner Tutorial Summary

This is the first Performance testing introduction tutorial. By explaining Manual Performance Testing, we explained why it is difficult to do that. Discussed more on need of Automated Performance Testing.

The basic flow of Automated Performance Testing is explained below. This process is followed by almost all tools.

We are using HP LoadRunner load testing tool as it is widely used most powerful tool. For better understanding, we’ve explained how LoadRunner works with practical examples.

Following basic terminologies that are used in Performance testing are discussed in detail:

• Business Process
• Action, Scenario
• Transaction
• Virtual User (Vuser)
• Rendezvous point
• Check point.

It is important to know these as we will be using these most commonly.

Major components of LoadRunner

• Vugen
• Controller
• Load Generator
• Analysis

For performance testing, we are going to use these components.

Finally, we discussed the process that we need to follow for successful performance testing. This includes end to end performance testing.

VUGen Recording Options part I

Vugen Recording Options – Part I Tutorial Summary

This tutorial covers the Vugen Recording Options. Apart from this, it also covers:

• Script Section
• New Virtual User dialog
• Start Recording dialog

In Script Section, we discussed three sections of the script (vuser_init, Action, vuser_end) and running sequence.

On New Virtual User Dialog, we try to touch base with all the fields and their importance so that while selecting the protocol for scripting, user should know its significance. This is the first step for script creation. VuGen provides option to create Single Protocol and Multiple Protocol script.

On Start Recording Dialog, we discussed the fields with their valid input data. This is second step for script creation. From this dialog type of application, browser, URL, working directory, and “Record into Action” options are selected.

In Recording Option, we covered the following topics in detail:

1. Scripts
2. Protocol
3. Recording
4. Port Mapping
5. Advanced Settings
6. Correlation
7. Code Generation

Script – This provides option to select the scripting language along with few settings related to the script. For Web (HTTP/HTML) protocol, the scripting language is C.

Protocol – This displays the protocol that we selected on New Virtual User Dialog box.

In the part-1, we have seen script sections and different dialogs.  For Recording options, we have seen how to select scripting language and confirm the protocol that is going to be used while scripting.

VUGen Recording Options part II

Vugen Recording Options Part II Tutorial Summary

This tutorial covers the remaining Recording options. In part-1 we have seen Script and Protocol. The other options are:

• Recording – Selection of mode or http/html level can be done from this. We discussed in detail URL and HTMl mode of web (HTTP/HTML) protocol, which gives good understanding and idea about the major difference between them.
• Port Mapping– This provides option for Port Mapping.
• Advanced Settings– This covers few advanced settings related to script generation or script execution. We discussed each option available in detail.
• Correlation– This is related to Automated Correlation. Correlation rules are created and enabled from this. In short, we discussed the fields available for the users on this dialog.
• Code Generation– This enhance the data format capabilities of web protocol.

The part I and II tutorials explain all important fields on different dialog boxes related to recording options and protocol selection which user should know before using LoadRunner. This will make you ready for recording a script with all the required information  for VuGen configuration.
