I need to test multiple call-outs that return XML. Storing the XML inside my unit tests' mock class is not a great solution.
I'm wondering if there's another Salesforce object type I could paste the XML into that is accessible during unit tests. I know already that PageReference's getContent() doesn't do anything during unit tests (bummer).
Of course, of Apex allowed line-breaks inside string literals it would be easier to cut and paste the XML, but alas...
