Tests a "stack" fixture which provides a separate list to each scope which uses it.
Some notes:
- For each scope, define 2 fixtures of the same scope which use the "stack" fixture,
2016-07-12 07:33:16 +08:00
to ensure they get the same "stack" instance for that scope.
- Creates multiple test files, which tests on each modifying and checking fixtures to
