We cannot use it here, because it needs to be kept alive for the duration of the tests. The cleanup is called manually in destroy_all which is called at the end of the test suite.

When it is used for unit tests, it should be replaced by the `tmp_path` fixture provided by `pytest` since it will take care of cleanup automatically. Then there are a few cases in the code where it was used where it was replaced with `tempfile.TemporaryDirectory`. The latter has the advantage that it will be automatically cleanup when the object goes out of scope. A few places in the code still use `mkdtemp` since it needs to control the cleanup manually. The `temp_dir` fixture is also deprecated. It works exactly as the `tmp_path` fixture which ships with `pytest` and should be used instead.
