What is LoadRunner?
LoadRunner is a PerformanceTesting tool which was pioneered by Mercury in 1999. LoadRunner was later acquired by HPE in 2006. In 2016, Loadrunner was acquired by MicroFocus
LoadRunner supports various development tools, technologies and communication protocols. In fact, this is the only tool in market which supports such large number of protocols to conduct Performance Testing.
Why LoadRunner?
- Load Runner: One of the best automated performance testing tool.
- Uses ANSI C as the default programming language and other languages like Java and VB.
- No need to install it on the server under test. It uses native monitors.
- Supports all types of protocols (HTTP, FTP and SMTP).
- Easy to analyze the results and creating scripts.
As we know Load Runner was acquired by Hewlett-Packard organization. One of the best and most used tool by many organizations. Though it’s a paid tool, for perfect and easiness in use this tool is the best.
AngularJS follows Two-Way data binding model.
One-Way Data Binding
The one-way data binding is an approach where a value is taken from the data model and inserted into an HTML element. There is no way to update model from view. It is used in classical template systems. These systems bind data in only one direction.
For every tool, there is a testing process to test an application. For the Load Runner , the best process to follow is
The above model is the best model to follow for the performance test.
Components of Load Runner:
- Vuser Generator
- Controller
- Analyzer
Let’s discuss about each component briefly with related examples.
VUser Generator:
The first component and the basic component is “Vuser Generator”. In Load Runner tool, humans are replaced by Vusers who are the replica of humans. More number of Vusers can be worked on a single work station with different scenarios. Load runner can accommodate hundreds or even thousands of Vusers with different scenarios.
With the help of Vuser script, users can perform the tests. User can record and playback the application for script generation.By modification or editing the scripts, user can create different scenarios for different Vusers. With this load test can be made simple and easy with one workstation.
Load runner supports scripting languages like ANSI C, VB Script, JAVA etc.. C and VB scripting are the most used ones in load runner. In recent versions of load runner JAVA scripting has been implemented, which can be widely used.
Controller:
In Load Runner ‘Controller’ is used to control the VUsers with single work station with different scenarios assigned to VUsers.
Analysis:
After the performance test the user can view the results of the test in
graphs.More into the concepts of Load Runner. As we discussed, we start with
‘Vuser Generator’.
Vuser scripts are created by Virtual User Generator with the recording of activities
between client and server. It records the scripts. These scripts are used to emulate the
steps of real human users. Using Vugen, we can also run the scripts for debugging.
VuGen can be used for recording in windows platforms. But, a
recorded Vuser script can also be run on Unix platform.
Developing Vuser Script
is a five step process:
- Record a Vuser script
- Vuser Script Enhancement – by adding the control statements and other functions
- Run time Settings Configuration
- Running of Vuser Script on Stand Alone machine – Verify that the script runs correctly
- Integration of Vuser Script – into a LoadRunner scenario or Performance Center or Tuning module session or Business process monitor profile etc.
What Will We Learn In LoadRunner Training?
To understand concepts behind the performance testing and the detailed approach on how to use various components of Load Runner on various phases to test the performance of the application. Provide knowledge and confidence to the students with hands on experience to face the interviews and to handle projects assigned in their company.
At the end of the LoadRunner training, you will be able to
- Analyse the performance testing requirements
- Prepare scripts for the business functions provided in the scope
- Execute test rounds and analyse the results given by the tool/li>
- Reporting the performance observed
- Learn how to work with TestNG framework with DataDriven framework concepts
What Are The Prerequisites To Learn LoadRunner?
Knowledge in computers and understanding about software language
Scheduling Demo With Trainer:
If you would like to take the online demo for LoadRunner trainer can you please make an inquiry or fill the form for demo registration, one of our executives will arrange a meeting with the expert trainer.
