Exception when run load test use visual studio.

  Sometimes you can single run the performance test pass, but when add them to load test and run, will get exception, this topic will list some exception and give the solution.

 

1. Extraction Rule  ExtractHiddenFields  No hidden fields were found in the response. 

This because some times the hiden filed that request1 returned response will lost, can change another way to extract the field and used it in request2, anyway you  need to make sure there's no extract rule in your code, and also some times you don't need
to dynamic read the response, just debug and hard code some  this.Context value for some parameter that value won't change when you every run, likethis.Context["QueryStringParam8.wctx"].ToString(),
the extract rule actually will get part of the request1's reponse content string, it's always the same everytime run.

request33.Headers.Add(newWebTestRequestHeader("CRMWRPCToken", token));

request33.Headers.Add(newWebTestRequestHeader("CRMWRPCTokenTimeStamp", timeStamp));

 

This becuause you didn't input the right token when call the service. currently, 1 walk around is use fiddler to catch the request and hard code the token and timeStamp, but the token will change, if you change another machine to run test code or time out of
24 hour,

Another walk around:
