How does LoadRunner calculate concurrent users?
Actual Test:
- Run the actual test with a full load.
- Collate the result after test completion.
- Open the result file in LoadRunner Analysis Tool.
- Open the “Connections” graph. Graphs->Add New Item->Add New Graph->Web Resources->Connections.
- Hover the mouse on the graph and get the “Number of Connections” value.
What is correlation in LoadRunner?
LoadRunner Scripting. ‘Correlation’ term refers to the handling of dynamic values coming from the server. These dynamic values are the unique values which are generated by the server for security purpose like the session ID, authorization token etc.
How do you do auto correlation in LoadRunner?
To use the autocorrelation feature of LoadRunner, you have to enable ‘Automatically apply correlation rules’ option which is available at: Recording Options -> Correlations -> Configuration -> Scan for correlations applying -> Rule Scan -> Automatically correlate values found.
How can you set the number of vusers in LoadRunner?
11) How can you set the number of Vusers in LoadRunner? You can set the number of Vusers in the controller section while creating your scenarios. Many other advanced options like ramp-up, ramp-down of Vusers are also available in the Controller section.
What is concurrent users in load testing?
In load testing, the number of concurrent users is a pretty standard measure of throughput, and generally, it means the number of users that are accessing an application at any one point in time.
How do you measure concurrent users?
Calculating the Number of Concurrent Users For example, if your peak visits per hour is 200 visitors and the average visit duration is 6 minutes, the number of concurrent users that should be used to create 200 visits per hour is 20 concurrent users.
Why is correlation important in load performance testing?
Dynamic data in load testing requires correlation to enable load testing scripts to run accurately. It is important to keep this in mind when you use recording to generate a script. If the script is unable to replay accurately, there is a good chance that this is because dynamic data is involved.
What is difference between web_reg_save_param and web_reg_save_param_ex?
‘web_reg_save_param_ex’ has wildcard option with ‘Content Type’ and ‘Request URL’ in the ‘Filters’ section whereas ‘web_reg_save_param’ has wildcard character or digit option in LB and RB attributes.
What is the difference between web_reg_save_param and web_reg_save_param_ex?
What are concurrent users and simultaneous users?
Concurrent Users: When multiple users access a website but perform different-different actions at the same time is called concurrent users. Simultaneous Users: When multiple users access a website and Perform the same action at the same time is called simontenious users.
This is typically called Correlation in LoadRunner. In simple words, the solution by using Correlation is: Correlation is classified into 2 categories in VUGen/LoadRunner:
What is a concurrent user in performance testing?
In the performance testing term, you would say ‘a period of time’ implies ‘test duration’. Hence the users which are running under a test plan; irrespective of the activities they are doing; are ‘Concurrent Users’. The word simultaneous is used for the events that occur at a point in time.
How many concurrent travel agents can LoadRunner handle?
In the LoadRunner tutorial, there is one practice scenario which states: The application must successfully handle 10 concurrent travel agents. The application must be able to process 10 simultaneous flight bookings with response time not exceeding 90 seconds.
What is the difference between simultaneous and concurrent users?
Simultaneous users can be concurrent users, but concurrent users cannot be simultaneous users. Generally, the number of concurrent users on an application is more than the number of simultaneous users. All the simultaneous users must be active and perform the same activities at a point in time.
