Coarser Fixture Scopes

[ghost]

My conftest.py, probably non-ideal, attempts to depend a session-scoped SQLAlchemy engine upon the pyramid_config fixture. Py.test disallows depending a session-scoped fixture on another function-scoped fixture. A knob to control pyramid_config granularity would be nice.

@bradmwalker I'd stronglu suggest rather changing the session-scoped SQLAlchemy engine to be rather function scoped.

Se conftest.py for my pyramid_fullath pyramid's plugin: https://github.com/fizyk/pyramid_fullauth/blob/master/tests/conftest.py#L39

Session living in between tests suggest that the data might live also affecting other tests. Clean slate for each test is always preferable.

I use one session-scoped fixture for SA engine + sessionmaker initialization (and potentially schema initialization), and a dependent function-scoped fixture to yield individual sessions from the sessionmaker for clean state.

Session-scoping might be a sane default for the configuration fixture. Websauna sets session-scoping for its config and WSGI app fixtures: https://websauna.org/_modules/websauna/tests/conftest.html

Well... you might be right, that the config is simple enough to be session scoped anyway. It's not like it's a database...

@bradmwalker version 0.3.0 should be in a minute uploaded to pypi. Thanks for pointing out that the config fixture could be rather session scoped.

Happy testing.
