qalgebra.utils.testing.datadir(tmpdir, request)

Proto-fixture responsible for searching a folder with the same name of test module and, if available, moving all contents to a temporary directory so tests can use them freely.

In any test, import the datadir routine and turn it into a fixture:

>>> import pytest
>>> import qalgebra.utils.testing
>>> datadir = pytest.fixture(qalgebra.utils.testing.datadir)

qalgebra.utils.testing.check_idempotent_create(expr)
