Problem: Sometimes you want to be sure your Zope3 application is working independent of any objects already stored in the ZODB.
Solution: You replace the ZODB on filesystem with a mapping storage entirely in RAM.
In your 'zope.conf' file replace
<zodb> <filestorage>
path Data.fs
</filestorage>
</zodb>
with
<zodb>
<mappingstorage>
name AnyNameOrId
</mappingstorage>
</zodb>
Startup Zope3 as usual, add and remove some objects. Watch the transaction log: it is empty, nothing to undo. Watch the ZODBControl screen: database size starts at about 10KB, you can even pack it. Warning: all objects created get lost on shutting down the server.
Have fun ;)
