LoadRunner Interview Questions for Freshers

1) What is Loadrunner?

Load Runner is a Micro Focus performance testing tool that is commonly used for discovering performance bottlenecks in websites.

It is primarily used to evaluate the performance and behavior of a system under extreme stress.

Loadrunner software may simulate thousands of customers at the same time and test the important components of software under various scenarios.

It not only aids in testing but also in increasing performance.

This program supports a variety of testing categories, including Load, Stress, Endurance, Volume, and Spike Testing.

 

2) What are the benefits of LoadRunner?

The following are some common benefits of LoadRunner:

  1. It lowers the need for human connection.
  2. It eliminates the need for several systems.
  3. Making the most use of automation feasible
  4. It enables you to make better use of your time and money.

 

3) What are the different components of LoadRunner?

LoadRunner's many components are as follows:

  1. VuGen (Virtual User Generator): VuGen collects end-user business processes and develops a Vuser script (automated performance testing script) that mimics end-user activities. 
    These Vuser Scripts may also be utilized in other Micro Focus products like LoadRunner Cloud and Business Process Monitor.
  2. Controller: This component develops, conducts, maintains, and monitors load tests.
  3. Load Generator: This device generates load.
  4. Analysis: It is used to evaluate, understand, and compare the load test findings.

4) What is the Life Cycle of Performance Testing?

The six steps of Performance Testing Life Cycle are as follows:

Step 1: Analyze the system and identify essential transactions

Virtual User Generator

Step 2: Create virtual user scripts

Step 3: Specify user behavior

LoadRunner Control Unit

Step 4: Develop load testing scenarios

Step 5: Execute the load test scenarios and watch the results

LoadRunner Evaluation

Step 6: Examine the outcomes

 

5) What exactly is a load runner Agent?

The Agent acts as a bridge between the host machine and the controller.

6) How does one go about creating a Vuser Script?

A vuser script may be created in four steps.

  • Step 1- Record the Vuser Script.
  • Step 2- Playback and improve the recorded vuser script.
  • Step 3- Define and test the different run-time parameters.
  • Step 4- Use the script in a LoadRunner scenario.

 

7) What protocols does LoadRunner support?

The following protocols are supported by LoadRunner:

  • .NET Record / Display
  • Database
  • DCOM
  • GUI
  • Java Record and replay
  • Network
  • Oracle E-Business
  • Remote desktop
  • SAP
  • SOA
  • Web and Multimedia
  • Wireless
  • Web 2.0

 

8) What LoadRunner component may be used to record a script?

A script is recorded using the VuGen (Virtual User Generator) component. It enables you to write Vuser scripts for a wide range of application kinds and communication protocols.

9) How can you conduct a LoadRunner test?

Planning the Test –This involves creating a well-defined test strategy to ensure that the newly built or LoadRunner test scenarios can achieve the load-testing objectives.

Creating the Vuser scripts – involves the building of Vuser scripts that comprise numerous duties done by each Vuser during scenario execution.

Creating the Scenario –This describes the events that occur throughout the client/server testing session. A scenario has machines, scripts, Vusers, and a list of Vuser scripts that the Vusers run while the scenario is running. LoadRunner Controller is used to construct scenarios. Manual scenarios and goal-oriented scenarios can both be constructed.

Running the Scenario - You may run the full scenario, Vuser groups, or individual Vusers from this screen. Prior to testing, the server's load is simulated by telling many Vusers to do the tasks concurrently.

Monitoring performance - Transaction resources, database resources, and firewall resources may all be monitored using the LoadRunner online run-time.

Analyzing Test Results - While running a scenario, LoadRunner captures the application's (client/server system) performance under numerous loads. Its graphs and reports are used to analyze the output of the application or server.

 

10) What is the LoadRunner component used to playback a script in multi-user mode?

In multi-user mode, the Controller component is used to playback the script. This is done during a scenario run in which a Vuser Script is executed by a group of Vusers.

 

11) What are Vusers?

In LoadRunner, Vusers take the role of human users. Vusers mimic real-world user behavior by carrying out common business tasks in your application.

The actions that Vusers execute throughout the recording session are detailed in the Vuser script. Vuser scripts are generated using the VuGen component.

 

12) What are Vuser scripts?

It is the script that directs all of the User's actions in order to achieve a specified objective. When we run a scenario, each Vuser runs a Vuser script. The performance of the program is also monitored using a function created in the Vuser script.

 

13) How many different sorts of VUsers are there in LoadRunner?

 DB Vuser, SAP Vuser,GUI Vuser, Web Vuser, RTE (terminal emulator), People Soft, Java, and more types of Vusers are available in LoadRunner.

 

14) What exactly are standard logs?

The standard log keeps track of the functions and messages that are transmitted to the server.

 

15) What exactly are extended logs?

The extended log records detailed execution messages such as warnings and other information. It is employed throughout the debugging process.

 

16) How many VUsers do you need for load testing?

The number of VUsers required is determined by several factors, including the System Under Test (SUT), Hardware Settings, Network Configurations, Memory, Operating System (OS), and Performance Test Objective.

 

17) What are the advantages of using Vuser as a thread?

Running Vuser as a thread enables the generation of more virtual users from any memory due to the minimal memory footprint of the Vuser executing a thread.

 

VUSER SCRIPT

 

18) What are the different parts of a Vuser script?

Vugen is divided into three sections.

Vuser-init - This should be used to log in.

Action - This is used to keep track of the business process.

Vuser-end - This should be used to log off.

 

19) What does the "Vuser-init" Section mean?

Vuser-init records the pre-procedures, often known as the initialization operations before the program executes.

 

20) What is the meaning of the "Action" Section?

The action is used to document the business process (client activity).

 

21) What does the "Vuser-end" Section mean?

Vuser-end is used to record a server log-off.

 

22) What exactly is ramp-up?

The term "ramp up" refers to progressively raising a server's load. One example is increasing the number of Vusers. Go to 'Scenario Scheduling Options' to enable ramp Up.

 

23) What exactly is a ramp down?

The word "ramp down" refers to the process of progressively reducing the amount of demand on a server. One example is reducing the number of Vusers.

LoadRunner Interview Questions for Experienced

24) How do you configure the number of Vusers in LoadRunner?

While building scenarios, you may change the number of Vusers in the controller section area. In addition to this, there are numerous advanced choices in the controller area, such as Vuser ramp-up and ramp-down.

 

25) What exactly is a correlation?

Correlation is used in test scripts to cope with changeable variables. The dynamic values may vary based on each user activity (value changes when the same User performs the action again) or for other users (value changes when action is replayed with different users). In all cases, these variables are kept by correlation, guaranteeing that they do not degrade throughout execution.

 

27) What exactly is the scenario?

The scenario describes the events that will occur throughout each testing session. A scenario, for example, describes and controls the number of people to imitate, the actions to be taken, and the computers on which virtual users run their simulations.

 

28) How To Create A Scenario?

We must install a LoadRunner controller. Following that, we add the list of hosts (where the vuser script runs), vuser scripts (where the vuser executes), and vusers that run throughout the scenario.

 

29) How Does A Scenario Work?

To execute a simulation, open an existing scenario first - Set up the scenario - Configure the output directory - Run the scenario.

 

30) How many different sorts of scenarios are there in LoadRunner?

LoadRunner has two types of scenarios:

  1. Manual Scenario
  2. Goal-oriented Scenario
