Also, the problem can be caused by the fact that TestComplete may recognize host names incorrectly in some cases. If the previous suggestion does not help, try acting in the following way:
1. Uncheck the 'Correct Host Field' option in the Load Test editor. Please see the "Editing Load Test Properties" help topic for details.
2. If the original host name you typed in your web browser is other than the name specified in the 'Target Server' edit box in the recorded task, specify the original host name in the 'Target Server' edit box in the Load Testing Task editor.
3. If you still have some problems with some connections, you also need to change the HTTPConnection.Host property dynamically from script to make TestComplete establish a connection to the needed server. Please refer to the "HTTPConnection.Host" help topic for more information.
Now I use different login information for different users (read from an Excel file),
i specified the original host name in the 'target server'edit box and changed the HTTPConnection.Host property dynamically from script.
However I still get the same error messages about partially simulated connections.
(The changes do have some effect:
When I run the test for 2 virtual users and TestInstance.RunConcurrently is set to true
the Test log shows no errors in most cases.
When i run the test using the same login information I always get the errors as described above)
To help us investigate the problem, please zip your entire project suite folder along with the log of the failed test execution and send us the archive via our Contact Support form (http://www.automatedqa.com/support/message). Make sure that the messages in your log correspond to the latest version of your tests.
If I get this right, this status means that the server did not respond to the request at all. That is why TC cannot provide any further information on the error.
However, in some cases, the specifics of the HTTP task may cause the server to act in this way. We would probably be able to suggest something if you sent us your TC project (we have requested it).
