satpy.tests.reader_tests.test_viirs_edr module

Module for testing the satpy.readers.viirs_l2_jrr module.

Note: This is adapted from the test_slstr_l2.py code.

satpy.tests.reader_tests.test_viirs_edr.test_available_datasets(aod_file)

Test that available datasets doesn’t claim non-filetype datasets.

For example, if a YAML-configured dataset’s file type is not loaded then the available status is None and should remain None. This means no file type knows what to do with this dataset. If it is False then that means that a file type knows of the dataset, but that the variable is not available in the file. In the below test this isn’t the case so the YAML-configured dataset should be provided once and have a None availability.
