Hi, Request is available in the property "lisa.vse.http.current.transaction.body" and lisa.vse.response is in Transient form and that is why you are not getting it.
You can use the below code in a Scripted Assertion in VS Image Response Selection step and store the response into a property and use it later.
import com.itko.lisa.vse.stateful.model.TransientResponse;
responseList = testExec.getStateObject("lisa.vse.response");
TransientResponse response = responseList.get(0);
String respText = testExec.parseInState(response.getBodyText());
testExec.setStateValue("VsRsp",respText);
return true;
Hope the above information will help you.
Thanks,
Prema
