Hi..

Im unable to capture a value by correlation(both automatic and manual correlation).. pls help

my script

web_custom_request("G1136764O",
        "URL=http://119.151.20.229/API_SIT3/shopping/cart/G1136764O",
        "Method=POST",
        "Resource=0",

Because you are capturing on the send format and not at the location where it is being sent to the client from the server. You have a conceptual problem in how correlation works in that you attempting to correlate on the use of the value rather than the receipt of the value.

Speak with your mentor and your trainer to go through the standard training material/tutorial material on correlation once again

Side note: Since revenue is at risk ( Shopping Cart based application ) you should be applying the most senior people to the testing of this interface, not the least experienced

Hi James,

Can you please let me know what do you mean by " you are capturing on the send format and not at the location where it is being sent to the client from the server."

As you said I'm new to loadrunner correlation(but interested in learning). Please help. Thanks.

Also to help you understanding, I'm able to correlate jsessionid in the same script but not this product specific dynamic value.

I tried with this value also from generation log {"CartId":"V6834832W"}

from this i have taken left and right boundaries and included a backward slash\ before double quotes. Please suggest. What I'm missing ??

If your boss is asking you to perform in this role then your boss needs to send you to training, or at least have the time to go through the entire online tutorial, and provide you with a mentor. No online forum is s substitute for the minimum support of training and a mentor.

Anything else is setting you up for failure. This is not your fault, it is the fault of your management.

Your question was how to capture (correlate) information you send yourself. That is silly.

The correlation functions only look for data that you receive. Hence no match.

Either create a LR parameter or look for the value in the previous steps -- maybe it is in a different format.

Correlation and parameterization is well covered in the LoadRunner training.

Refer to this: http://motevich.blogspot.com/2007/11/loadrunner-webregsaveparam-boundaries.html

Tell us where you put your web_reg_save_param to G1136764O

Usually you have to do somewhere before the post request. Like JsessionId correlation - where did that occur?

It seems you expect these variables to be magically available when in fact they are typically generated in some web page prior to the post that needs them.
