Load Runner Interview Questions Expert Level 3

Questions 1 to 10

Question 1: How do you share automatic correlation rules created by you with your friend working on the same application?

 Automatic Correlation rules can be transferred through .cor file and the same file can be imported through VuGen

Question 2:What is Step download timeout error?

In loadrunner, If the application does not give any response in 120 seconds (2 min), step download timeout occurs. We can increase the step download timeout in Loadrunner to avoid this error.

Runtime Settings -> Preferences -> Options -> General -> Step Download Timeout 

Question 3: When do we use Web_Custom_request??

The name of the function itself suggests the custom request. Web_custom_request is the last option that vugen prefers while script creation. Vugen first tries to create the script using different web functions. The web_custom_request function is used by the vugen when it cannot interpret the requests with the other web functions.

Question 4: What are different types of goals in Goal-Oriented Scenario?

Load Runner provides you with five different types of goals in a goal oriented scenario

1) The number of concurrent Vusers,
2) The number of hits per second,
3) The number of transactions per second,
4) The number of pages per minute,
5) The transaction response time that you want in scenario.

Question 5: What are the advantages of “Run Vuser as a thread” over “Run Vuser as a process”?

Following are the advantages of “Run Vuser as a thread”:

When we use “Run Vuser as a process”, LR creates one process i.e mmrdrv.exe per Vuser, so if we have 15 users, Loadrunner will create 10 mmdrv.exe in our machine..

While using ‘Run Vuser as thread’ , LR creates 1 thread per vuser, So if we have 15 vusers then we will have 1 process with 15 threads running in it if the limit is 10 threads per process.

‘Run as a thread’ is more memory efficient then ‘Run as a process’ as less memory is consumed when we run vusers as a thread.
