Look at http://svn.zope.org/zope.testing/trunk/src/zope/testing/.

Unfortunately, there isn't really documentation on what layers
are for or how to write them.  This is a an ommission that needs
to be addressed.  You should be able to use the new test runner
in 2.8.  We use it with 3.1. It is included in 2.9 and 3.2.

To see how layers are are used, look at zope.app.testing.functional
on the Z3 trunk.  The Zope 3 functional tests are now provided via
a layer.  In the coming months we'll be releasing packages that use
layers to provide independent functional tests.
