satpy.tests.reader_tests.test_netcdf_utils module

Module for testing the satpy.readers.netcdf_utils module.

class satpy.tests.reader_tests.test_netcdf_utils.FakeNetCDF4FileHandler(filename, filename_info, filetype_info, auto_maskandscale=False, xarray_kwargs=None, cache_var_size=0, cache_handle=False, extra_file_content=None)

Bases: NetCDF4FileHandler

Swap-in NetCDF4 File Handler for reader tests to use.

Get fake file content from ‘get_test_content’.

get_test_content(filename, filename_info, filetype_info)

Mimic reader input file content.

Parameters:

• filename (str) – input filename

• filename_info (dict) – Dict of metadata pulled from filename

• filetype_info (dict) – Dict of metadata from the reader’s yaml config for this file type

Returns: dict of file content with keys like:

• ‘dataset’

• ‘/attr/global_attr’

• ‘dataset/attr/global_attr’

• ‘dataset/shape’

• ‘dataset/dimensions’

• ‘/dimension/my_dim’
