wscltest is a tool to test webservices with the purpose to be easy to use.
It's a command line tool that you execute from a folder where there is a configuration file along with some SOAP request messages. You type “wscltest”, press Enter, and the request messages are sent (in a sequential order) to the service. The responses are saved in the same folder (the working directory).
wscltests is free software, licensed under GPL v. 2
Give it a try. Read the tutorial (a short one, and easy to understand, I hope), download it, and test it. wscltest can run both on Linux and Windows.
