How do you handle errors in LoadRunner?
Excerpt from “LoadRunner Virtual User Development Guide” In the script’s Run-time Settings, you can set the error handling method when the script is running. Go to Run-time Settings, switch to the Miscellaneous tab, you can see the first setting of Error Handing: Continue on error, as shown in Figure 1-30.
If you want to choose any specific value then you can append “_” in the correlation parameter and pass into the subsequent request. denotes the place of the item appeared on the webpage. For example, if you need to pick 2nd value then the correlation parameter will be “c_itemName_2”.
How do I enable 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.
Why do we use correlation in LoadRunner?
LoadRunner provides a mechanism to easily perform correlation in automatic fashion. VUGen will require you to run a recorded script at least two times so it can internally compare the varying values in the server response. Automatic correlation can be classified into 3 categories: Auto-Detect Correlation.
What is error handling in loadrunner?
Error Handling: This setting handles the errors during a performance test or while replaying the script.
What is correlation and parameterization?
Correlation is handling of dynamic value which is returned from the server. Parameterization takes care of user inputted values, while correlation handles data which is returned by the server for any request. Introduction. Parameterization is used for fetching the values from the CSV file.
What is the difference in running the vuser as a process and as a thread?
“When Vuser is run as a process, the same driver program is loaded into memory for each Vuser. This will take a large amount of memory and will limit the number of Vusers you can run on a single generator. When Vuser is run as a thread, only one instance of driver program is shared by given number of Vusers.
How does correlation work in the Load Runner?
Parameterization in LoadRunner was explained in detail in our previous tutorial. Here, in this tutorial, we will explore the concept of Correlation in LoadRunner in detail in simple terms along with a classic video tutorial for your reference. Correlation is done for the dynamic value or the value returned by server for any request.
How to correct correlation problem in…?
Action.c (36): Error -35061: No match found for the requested parameter “CorrelationParameter”. Check whether the requested boundaries exist in the response data. Also, if the data you want to save exceeds 9999 bytes, use web_set_max_html_param_len to increase the parameter size [MsgId: MERR-35061]
Although 60-90% dynamic values (sometimes 100%) can be correlated using automatic correlation (it is a generic statement; not applicable to all protocols). Automatic correlation is a rule-based approach and dynamic values are identified based on the defined rules.
Is there a way to automatically correlate values in vugen?
If you click on automatically correlate values found, VUGen will not prompt you with the choice once a correlation candidate is found, instead, it will just correlate them. We will understand API used for correlation later. However, it is advisable to use HTML comparison instead of text comparison.
