I see several other questions about load testing web services. But as far as I can tell those are all synchronous load testing tools. (Meaning they send a ton of requests but the go one at a time.)
I am looking for a tool where I can say, “I want 100 requests to be launched at the exact same time”.
Now, I am new to the whole load testing thing, so it is possible that those tools are asynchronous and I am just missing it.
Anyway, in short my question is: Is there a good tool for load testing WCF Web Services asynchronously (ie lots of threads).
In general, I recommend you look at soapUI, for anything to do with testing web services. They do have load testing features in the Professional edition (I haven’t used these yet).
In addition, they’ve just entered beta with a loadUI product. If it’s anywhere near as good as the parent product, then it’s worth a hard look.
