One of the powerful feature of QEngine WebPerformance Testing is the ability to automatically extract the request parameters from the previous response to use it in the next request. Hence any kind of dynamic parameters can be extracted automatically by QEngine.

In Web Performance Testing, the transaction with the web application will be recorded as URL with the associated parameters.The parameters may contain SessionID / VIEWSTATE variables, which will be used to maintain the session. These parameters will change time to time. These dynamically changing values can only be taken by parsing the response content of the previous request or from cookies.

With QEngine Auto parameterization option, QEngine will automatically parse the response content of the last request and extract the required parameter values and use it in the subsequent request. This will reduce the burden of parameterizing each and every request parameter manually.

Hence you may required to parameterize only the needed parameters, if required.
