Below is an example of using Savon to test SOAP endpoints of a Rails app that uses Wash out. The Savon approach works, but Savon likes to mangle the XML you feed it by wrapping it in the SOAP Envelope and Body tags. Therefore, I'm trying to duplicate with Faraday what's working with Savon so I can fully control the XML being fed to the SOAP endpoint. HTTPI is mounting the app to "http://app" such that Savon just needs "http://app/soap/wsdl" to connect. Faraday, however, says it was fed an invalid node or server name. Is there a Faraday friendly way to mount the app within the testing framework? · GitHub
