What Are The Features Of Microfocus Loadrunner?
Performance testing software includes Micro Focus LoadRunner. The LoadRunner programme evaluates an IT system's performance by simulating the simultaneous activities of many users, placing pressure on the system, and then timing how quickly the system reacts to user inputs. The method slows down, and response times lengthen as the load rises.
For instance, 1,000 consumers making transactions simultaneously on an e-commerce website can be simulated using Micro Focus LoadRunner. The test might start with ten users and build up to 1000 over time, measuring response times as the load rises and indicating the point at which the response times become intolerable. Micro Focus LoadRunner frequently improves performance. To know more about the loadrunner, join loadrunner training online.
Critical features of microfocus loadrunner
LoadRunner simulates human users by generating numerous concurrent processes known as virtual users or Vusers (in Windows, Vusers are implemented as processes or threads). Every Vuser executes a script, which is a little programme. The Vuser Generator, the Load Generator, the Controller, and LoadRunner Analysis are the four primary parts of HP LoadRunner.
1)Vuser generator
Scripts are created, modified, and debugged with the help of the Vuser Generator, or VuGen. Typically, scripts are written by capturing human users' behaviours on the system being tested. The test application's information is entered into the VuGen before it is launched to create a script in recording mode. The user executes the script's instructions on the test application while the VuGen records each action. The VuGen can then replay the user's activities after completing the recording.
2)Load generator
The VuGen can play back any script, but it can only do so one at a time and cannot produce large loads. The load generator is in charge of doing this. Depending on settings, the Load Generator creates several Vusers and gives each one a script. Each Vuser is implemented as either a thread or a process. The test's time is then spent with each Vuser running its script. The Load Generator is a background-running, non-interactive software with no user interface. The Vusers are started and stopped, and any choices and settings are applied according to the controller's commands. The Load Generator may be deployed and controlled by a single controller in one or more instances.
3)Controller
Performance tests are carried out under the direction of the LoadRunner Controller. It provides a user interface configuring the test's many elements, including the number of Vusers, the scripts each Vuser will execute, and the test's duration. Moreover, tests are started, stopped, and reported on via the user interface while they are being done.
4)Loadrunner Analysis
Each LoadRunner test's findings are kept in its database. After the trial, Micro Focus LoadRunner Analysis reads this database, analyses the data, and presents the results. The output of any monitors that were set up in the controller before the test, as well as the response times and throughput, are included in the results. There are numerous methods to present the facts. These consist of tables, graphs with varied levels of detail, and exports to Microsoft Excel or.csv files. The number of users participating in the test, the transaction throughput during the test, and essential resource use metrics for the application servers and database servers are among the statistics that are frequently analysed.
