Today, I have to work on WCF web service test client. I need to develop a client which can be used to test our WCF web service. This tool should provide beautiful graphical interface. QA department need this tool to test our service easily. I searched on internet and found many tools. Many of them are commercial, some tools are free. I shortlisted two tools which are available on codeplex. These are wizdl (https://wizdl.codeplex.com/) and Storm (http://storm.codeplex.com/). These tools are good for web service testing but I like Storm. Its look is very profession and very easy to use. I highly recommend this tool if you want to test your web service.
