"""ZopeTestCase framework

COPY THIS FILE TO YOUR 'tests' DIRECTORY.

This version of framework.py will use the SOFTWARE_HOME
environment variable to locate Zope and the Testing package.

If the tests are run in an INSTANCE_HOME installation of Zope,
Products.__path__ and sys.path with be adjusted to include the
instance's Products and lib/python directories respectively.

If you explicitly set INSTANCE_HOME prior to running the tests,
auto-detection is disabled and the specified path will be used 
instead.

If the 'tests' directory contains a custom_zodb.py file, INSTANCE_HOME
will be adjusted to use it.

If you set the ZEO_INSTANCE_HOME environment variable a ZEO setup 
is assumed, and you can attach to a running ZEO server (via the 
instance's custom_zodb.py).

The following code should be at the top of every test module:

  import os, sys
  if __name__ == '__main__':
      execfile(os.path.join(sys.path[0], 'framework.py'))

...and the following at the bottom:

  if __name__ == '__main__':
      framework()
