[ZODB-Dev] Snapshotting state with DemoStorage

[Martin Aspeli]

Hi,

I'm trying to set up a test case with Selenium RC. For this I need to be 
able to set up a layer that includes a base state Plone site with some 
data. I then need to be able to execute a number of Selenium tests 
(which will perform operations that do ZODB commits across multiple 
requests), rolling back to the snapshot state after each one.

Is it possible to create a fast "snapshot" with DemoStorage e.g. in a 
ZopeTestCase layer, and then have the tear-down after each test revert 
to this state? Doing the full setup (creating a new Plone site, 
populating it) between each test run is prohibitively expensive!

I also saw zc.demostorage2, but didn't quite understand how it's 
different or if it would help here.

Cheers,
Martin
