The main steps include:. During performance test execution, Vusers run concurrently and generate the traffic on the server. On the completion of the test, LoadRunner collates the results and save in a file called Raw results. This file can be opened through the Microfocus Analysis tool and performed further analysis on the test result.
The selection of the performance testing tool depends on the technology and the budge of the client. LoadRunner is a licensed performance testing tool which also has a free trial version. Today, companies and clients have multiple options for performance testing tool in the market but many reputed clients still keep their faith in Loadrunner and want to continue with it.

See why on the NeoLoad vs LoadRunner page. Contact Us. What is LoadRunner? About NeoLoad NeoLoad provides a graphical interface which enables users to test up to 10 times faster than LoadRunner. Anyone in the team can become a performance tester See how NeoLoad can help you design tests faster.

The controller The controller is the central component of the LoadRunner testing tool. Test execution management Performance data collection Number of virtual users VUs that need to be simulated for each test Gather results periodically Test duration with ramp-up and ramp-down times and number of simultaneous VUs IP spoofing Load generators used in testing Error reporting Transaction Declaration, etc.
Load generators Load generators are the components of LoadRunner that simulate the hundreds or thousands of VUs as defined in VuGen for testing. The analysis component Once your load scenarios have been executed, the analysis component comes into play. The process of load testing with LoadRunner can be divided into three main steps: Design test scripts using VuGen Define the execution of tests Analyze results.
The above 2 facts combined give us the total number of users with which we need to test the system for performance. Statistics and observations drawn from Performance Testing are greatly influenced by numerous factors as briefed earlier.
It is of critical significance to prepare Test Data for Performance Testing. Sometimes, a particular business process consumes a data set and produces a different data set. Take below example:. Speculate each and every factor which could possibly affect the performance of a system.
Next step after planning is to create VUser scripts. Scenario execution is where you emulate user load on the server by instructing multiple VUsers to perform tasks simultaneously. You can set the level of a load by increasing and decreasing the number of VUsers that perform tasks at the same time. This execution may result in the server to go under stress and behave abnormally.
This is the very purpose of the performance Testing. The results drawn are then used for detailed analysis and root cause identification. During scenario execution, LoadRunner records the performance of the application under different loads. The statistics drawn from test execution are saved and details analysis is performed.
Performance Testing is always done for client-server based systems only. This means, any application which is not a client-server based architecture, must not require Performance Testing. For example, Microsoft Calculator is neither client-server based nor it runs multiple users; hence it is not a candidate for Performance Testing. It is of significance to understand the difference between Performance Testing and Performance Engineering. An understanding is shared below:.
Performance Testing is a discipline concerned with testing and reporting the current performance of a software application under various parameters.
