Check the chunk size limit computations.

satpy.tests.test_utils.test_chunk_size_limit_from_dask_config()

Check the chunk size limit computations.

satpy.tests.test_utils.test_convert_remote_files_to_fsspec_filename_dict()

Test convertion of remote files to fsspec objects.

Case where filenames is a dictionary mapping readers and filenames.

Test convertion of remote files to fsspec objects.

Case where the some of the files are already FSFile objects.

satpy.tests.test_utils.test_convert_remote_files_to_fsspec_local_files()

Test convertion of remote files to fsspec objects.

Case without scheme/protocol, which should default to plain filenames.

Test convertion of remote files to fsspec objects.

Case with mixed local and remote files.

satpy.tests.test_utils.test_convert_remote_files_to_fsspec_storage_options(open_files)

Test convertion of remote files to fsspec objects.

Case with storage options given.

satpy.tests.test_utils.test_convert_remote_files_to_fsspec_windows_paths()
