Instead of having a module full of tests specifically for pint, one for sparse, one for cupy, one for awkward, etc. etc. etc. those projects could just write a minimal test module like this:

```python
import xarray
import sparse

xarray.testing.test_nep18_module(
    sparse,
    # TODO: lambda to create an array
    # TODO: list of xfails 
)
```
which would automatically expand into a comprehensive suite of tests thanks to pytest parameterize/fixture magic.
this would allow developers of numpy-like libraries to just test their package vs what's expected from a generic NEP-18 compliant package.","{""total_count"": 2, ""+1"": 2, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,667864088
