490228661,MDExOlB1bGxSZXF1ZXN0MzE0ODc0MDI5,3283,Add hypothesis test for netCDF4 roundtrip,327925,open,0,,,5,2019-09-06T09:33:48Z,2022-11-21T22:45:13Z,,MEMBER,,0,pydata/xarray/pulls/3283,"Part of #1846: add a property-based test for reading & writing netCDF4 files.

This is the first time I've played with Hypothesis, but it seems to be working - e.g. I got an error with float16, and the [netCDF docs show](https://www.unidata.ucar.edu/software/netcdf/docs/data_type.html) that 16-bit floats are not a supported data type.

However:

- This currently only tests a dataset with a single variable - it could be extended to multiple variables if that's useful.
- It [looks like](https://www.unidata.ucar.edu/software/netcdf/docs/netcdf_data_set_components.html#Permitted) netCDF4 should support unicode characters, but it failed when I didn't have `max_codepoint=255` in there. I don't know if that's an expected limitation I'm not aware of, or a bug somewhere. But I thought I'd make the test pass for now.
