Recommendations for Soap Webservice Testing Apps

I was looking for some recommendations for testing SOAP webservices. I want to be able to create requests from WSDL, see those requests, and inspect responses. I would also like it to work with WS* compliant services (such as when using WCF wsHttpBinding).

Any suggestions?

Which tool is used for SOAP API testing?

SoapUI is the world's leading Functional Testing tool for SOAP and REST testing.

How do you test SOAP messages?

In the Import from File window, navigate to the XML or HTTP file that you want to import and click Open. The editor is populated with the SOAP message. If your test uses unreferenced attachments, scroll to the bottom of the value editor pane. Right-click attachments and select Add Elements.

I use SoapUI (http://www.soapui.org/) for all of my SOAP testing. It's a different client, so it doesn't really help if the client is making a bad request. In that case, I just use the normal debugger or Firebug to inspect the request/response.
