 very nice @almaleksia ! if you wanted to move the JOIN_TYPES to the top-level ``pandas/conftest.py`` (and make it a fixture),  and prob rename to join_types, would be *really* helpful. note that this will percolate to lots of other modules, mainly in pandas/tests/reshape where they are actually used.  I *think* we have an issue about this (or at least about generally moving things like this to fixtures). Also would be great to split up pandas/tests/frame/test_indexing.py along the same lines as you did here :-D @jreback thanks! I can create separate PRs for joins and frame/test_indexing refactoring
