Hi , Iam new in load testing.

I would like to know which test system I would use to do load runner testin , production system or test system?

which system( production system or test system ) url I give to create vgen script.
What else I need to need before I start doing load testing.
Please sombody help me.

I created vgen script by using test system , but now my manager saying you are not suppose to use test system for load runner testing.

Please help..

You can run a load test against your test system or against your production one. The question is not a LoadRunner related but really depends on what you are trying to achieve. LoadRunner is just a facilitator here.

If your test system is not an ad-hoc one, meaning it has sufficient HW for your application it can be used for the load test. Testing against production environment usually requires coordinating the test with the people responsible for the system since it might damage end user experience that time. The real question is what you are trying to achieve.

Anyway, best practice you should apply regardless is having generic VuGen scripts that can run against any environemnt and not specifically against the one your recorded the script against.

Good luck

Hi
I'm still new to the field of testing ..but reading shlomini's answer, i'm a little confused..how can we create generic Vugen Scripts?
What if the production url is different from test?Eg if it is "prod" and "QA.prod".
Do help with the clarification

There isn't much different if both your environmental setup are the same. Most likely its a different IP, eg. prod is 172.1.1.21 while QA.prod is 168.1.1.21. In this case, you have to parameterize the IP address of your scripts. If they are identified by hostname, it will be easier.

As shlomini mentioned, its what you want to achieve. Then create a generic script (mentioned above) that can work in the different environment.

I also suggest you work with LoadRunner VuGen Tasks mode. it will guide you step by step what do to in order to create a generic script.

To activate the tasks mode, invoke VuGen and from the View menu select Tasks.

go through the LR manuals

The Load Test should ideal happen on the environment that the application will be hosted on to (to-be- production environment).if the production enivronment is already set up then try testing on DR environment which likely in most cases replica of production. if not try get an environment which as very close to production. Never test on an environment which has specs higher than the production, then you cannot validate your results.
