Does VS supports web sockets to record performance test?

Question

Hi

We need to load test an application which uses web sockets.

Is it possible to record web sockets performance tests using the VS ?

Thanks

Hi Sathish Selliah,

As far as I know, the websockets is TCP-based communication between client side and server side. But according to the description for Web Performance Test engine in Visual Studio, it should work on HTTP layer.

https://msdn.microsoft.com/en-us/library/ff520100(v=vs.110).aspx

So I'm afraid that we could not record web sockets performance test using Visual Studio Web Test Recorder directly.

Please try use Fiddler to capture the web sockets request and the import these request into Visual Studio to check whether they can playback in Visual Studio Web Performance.

Best Regards,
Weiwei

Hi Sathish

Out of the box there's support for anything on the http stack.  If you want to test another protocol do it in a unit test and then load test the unit tests.  I have done this to performance test smtp & pop3 servers in the past.
