make_instance()

ApdbConfig lsst.dax.apdb.tests._apdb.ApdbSchemaUpdateTest.make_instance	(		self,
		**Any	kwargs )

Make config class instance used in all tests.

This method should return configuration that point to the identical
database instance on each call (i.e. ``db_url`` must be the same,
which also means for sqlite it has to use on-disk storage).
