Webservice integration test?

Hey railers,

I’m a newbie, so excuse me if the answer is obvious. We’re using a
layered
dispatch model for our back-end and I’d like to run some integration
tests
for things login and session authentication. The integration examples
I’ve
seen, however, make get/post calls to controllers and not web services.
How
would I do a sess.post w/ SOAP headers? Do I use the invoke_layered
method?

Thanks,

Jaime
