[Zope-dev] Unit tests for Zope products: how to test HTTP access to objects in ZODB?

Hello: I am trying to add some unit tests for my XMLTransform product that test URL to Zope object traversal. For example, I want to ensure that one XSLT (a zope object) can include another using <xsl:include "../foo.xsl"/> Zope should transform the above into a request for a zope object with an ID of "foo.xsl" in the parent folder of the original XSLT. My question: how have you, dear reader, tested Zope's mapping of URLs (relative and/or absolute) to objects in ZODB? I am hoping that it can be done, possibly at the cost of bringing in additional Zope machinery (which means additional unit test startup time)...? Thanks in advance, --Craeg
