[Zope] FunctionalTestCase commits transactions

[Peter Bengtsson]

I'm trying to get zope.testbrowser to work in Zope 2.10. After a lot
of guesswork (easy_install zope.testbrowser broke my environment, Zope
2.11 isn't setting up session container, used various blogs tips to
get adapters right) I got it running and I can now do stuff like
browser.open(self.folder.myapp.absolute_url()) in python unit test.
However, I have a problem. The app uses ZSQL Methods and when the test
finishes the transaction is not rolled back and I'm not interested in
manually resetting the test database.
Is this so deliberately?
Do I really have to manually reset the database?

I noticed that FunctionTestCase
(lib/python/Testing/ZopeTestCase/ZopeTestCase.py:116) inherits from
functional.Functional which inherits from sandbox.SandBoxed which,
although I don't understand it, seems to do things differently to the
non-functional approach which inherits from base.TestCase.

Although I'm not using it, function.Functional adds the nifty function
publish() which I'm not using but it's not a transaction.commit() in
it. Why??
And what does that decorator actually do?

class Functional(sandbox.Sandboxed):
    ...
    __implements__ = (interfaces.IFunctional,)

    @savestate
    def publish(self, path, basic=None, env=None, extra=None,
                request_method='GET', stdin=None, handle_errors=True):
        '''Publishes the object at 'path' returning a response object.'''
       ...

        # Commit the sandbox for good measure
        transaction.commit()
        ...
