-The default ordering of tests created by the unittest test loaders is to group all tests from the same modules and classes together. This will lead to ``setUpClass`` / ``setUpModule`` (etc) being called exactly once per class and module. If you randomize the order, so that tests from different modules and classes are adjacent to each other, then these shared fixture functions may be called multiple times in a single test run.

-Shared fixtures are not intended to work with suites with non-standard ordering. A ``BaseTestSuite`` still exists for frameworks that don't want to support shared fixtures.

-If there are any exceptions raised during one of the shared fixture functions the test is reported as an error. Because there is no corresponding test instance an ``_ErrorHolder`` object (that has the same interface as a :class:`TestCase`) is created to represent the error. If you are just using the standard unittest test runner then this detail doesn't matter, but if you are a framework author it may be relevant.
