[v3] Files created during tests

10

Running the [dimension separator tests](https://github.com/zarr-developers/zarr-python/blob/v3/tests/v2/test_dim_separator.py) in `v3` results in a directory called `src/fixture` being created, which is not the correct thing for a test to be doing. Files generated for...

[V3] Should `Group` be dict-like?

1

Although the [V3 `Group`](https://github.com/zarr-developers/zarr-python/blob/475ce01d22ffff502545c1d7e4b8f72c1f6fa629/src/zarr/v3/group.py#L325) does not inherit from `Mapping` or `MutableMapping`, it has methods that are mapping-like, e.g. `__contains__`, `__getitem__`, `__iter__`, `__delitem__` etc. I think this makes sense in terms...
