Load your own instance by name

If the user is the instance owner, load the instance by name:

# no instance connected, prompts to connect
import bionty

ln_setup.connect(
    "mydata", _reload_lamindb=False
)  # also test passing _reload_lamindb explicitly

# this is a local intstance, no spaces needed
assert ln_setup.settings.instance.available_spaces is None

# pertdb is not in the (schema) modules of mydata
with pytest.raises(ModuleWasntConfigured):
    # _check_instance_setup is called inside
    import pertdb

# bionty was loaded as a default module
import bionty  # noqa
