If you're using Zope 2.10 or higher, you can either use the "native"  ZPT 
implementation from Zope 3 (see zope.pagetemplate module) or you use the 
Zope 2 implementation (which is basically only a wrapper around the Z3 
implementation). In this case you might look at the unittests in 
testZopePageTemplates.py or otherwise you check the doctests of 
zope.pagetemplate.
