Hi ,

Its a very useful . I have one issue in Avg.Response time and Avg. Transaction Time both the values for my loadtest has no values i mean '-' and '0'.

Even i have defined transaction in my unit test as below,

TestContext.BeginTimer("t1");

List<PersonLocationInformation> actual = target.TestSummary(100);

TestContext.EndTimer("t1");

Please help me to fix this issue

Thanks in advance

Is there at least 1 iteration of the unit test completing. Transaction counters are not reported until at least one iteration completes

Hi Sean,

I am new to this concept. I have to perform load testing of a web service and for this your article is quite informative, an excellent one.

However, I need some guidence as well. I have to know the time in which my web service does its processing and sends back the xml response.I need to do this load testing for a constant load of 1000 users and want to know this performance unit(time it takes to process a request and send back the response) under such load.Can you please guide me regarding it?

Moreover, could you please clarify if a load of 1000 user means that the load test would continously send 1000 request to the web service after each time interval as stated in sample rate or it means that it just send a request to 1000 users and then samples the response and gives the data accordingly.

It would be of real help if you could guide me regarding these issue.

Thanks in anticipation

Rmehera,

You could get the time that it takes for the web service calls by using the timer objects described in this article. Just surround your call with begin and end timer calls.

1000 users means that we will have 1000 virtual users executing your unit test or web test. So if the only thing in your unit test is a call to web service, then it basically means that there would be continuous requests from 1000 users.
