软件测试LoadRunner面试题：How did you find database related issues?
By running .Database. monitor and help of .Data Resource Graph. we can find database related issues. E.g. You can specify the resource you want to measure on before running the controll
软件测试LoadRunner面试题：How did you find web server related issues?
Using Web resource monitors we can find the performance of web servers. Using these monitors we can analyze throughput on the web server, number of hits per second that occurred during
软件测试LoadRunner面试题：If web server, database and Network are all fine where could be the problem?
The problem could be in the system itself or in the application server or in the code written for the application.
软件测试LoadRunner面试题：How do you identify the performance bottlenecks?
Performance Bottlenecks can be detected by using monitors. These monitors might be application server monitors, web server monitors, database server monitors and network monitors. They
软件测试LoadRunner面试题：Explain the Configuration of your systems?
The configuration of our systems refers to that of the client machines on which we run the Vusers. The configuration of any client machine includes its hardware settings, memory, operat
软件测试LoadRunner面试题：What is the relation between Response Time and Throughput?
The Throughput graph shows the amount of data in bytes that the Vusers received from the server in a second. When we compare this with the transaction response time, we will notice that
软件测试LoadRunner面试题：If you want to stop the execution of your script on error, how do you do that?
The lr_abort function aborts the execution of a Vuser script. It instructs the Vuser to stop executing the Actions section, execute the vuser_end section and end the execution. This fun
软件测试LoadRunner面试题：What is the advantage of running the Vuser as thread?
VuGen provides the facility to use multithreading. This enables more Vusers to be run per generator. If the Vuser is run as a process, the same driver program is loaded into memory for
软件测试LoadRunner面试题：What is Ramp up? How do you set this?
This option is used to gradually increase the amount of Vusers/load on the server. An initial value is set and a value to wait between intervals can be specified. To set Ramp Up, go to
软件测试LoadRunner面试题：Where do you set Iteration for Vuser testing?How do you perform functional testing under load?
We set Iterations in the Run Time Settings of the VuGen. The navigation for this is Run time settings, Pacing tab, set number of iterations. Functionality under load can be tested by ru
软件测试LoadRunner面试题：What are the changes you can make in run-time settings?
The Run Time Settings that we make are: a) Pacing – It has iteration count. b) Log - Under this we have Disable Logging Standard Log and c) Extended Think Time – In think ti
软件测试LoadRunner面试题：How do you write user defined functions in LR? Give me few functions you wrote in your previous project?
Before we create the User Defined functions we need to create the external library (DLL) with the function. We add this library to VuGen bin directory. Once the library is added then we
软件测试LoadRunner面试题：How do you debug a LoadRunner script?
VuGen contains two options to help debug Vuser scripts-the Run Step by Step command and breakpoints. The Debug settings in the Options dialog box allow us to determine the extent of the
软件测试LoadRunner面试题：When do you disable log in Virtual User Generator, When do you choose standard and extended logs?
Once we debug our script and verify that it is functional, we can enable logging for errors only. When we add a script to a scenario, logging is automatically disabled. Standard Log Opt
软件测试LoadRunner面试题：Where do you set automatic correlation options?
Automatic correlation from web point of view can be set in recording options and correlation tab. Here we can enable correlation for the entire script and choose either issue online mes
