satpy.tests.reader_tests.test_utils module

Testing of helper functions.

class satpy.tests.reader_tests.test_utils.TestHelpers(methodName='runTest')[source]

Bases: TestCase

Test the area helpers.

Create an instance of the class that will use the named test method when executed. Raises a ValueError if the instance does not have a method with the specified name.

test_apply_rad_correction()[source]: Test radiance correction technique using user-supplied coefs.

test_generic_open_BZ2File(bz2_mock)[source]: Test the generic_open method with bz2 filename input.

test_generic_open_FSFile_MemoryFileSystem()[source]: Test the generic_open method with FSFile in MemoryFileSystem.

test_generic_open_filename(open_mock)[source]: Test the generic_open method with filename (str).

test_geostationary_mask()[source]: Test geostationary mask.

test_get_earth_radius()[source]: Test earth radius computation.

test_get_geostationary_angle_extent()[source]: Get max geostationary angles.

test_get_geostationary_bbox()[source]: Get the geostationary bbox.

test_get_user_calibration_factors()[source]: Test the retrieval of user-supplied calibration factors.

test_lonlat_from_geos()[source]: Get lonlats from geos.

test_np2str()[source]: Test the np2str function.

test_pro_reading_gets_unzipped_file(fake_unzip_file, fake_remove)[source]: Test the bz2 file unzipping context manager.

test_reduce_mda()[source]: Test metadata size reduction.

test_sub_area(adef)[source]: Sub area slicing.

test_unzip_file(mock_popen, mock_bz2)[source]: Test the bz2 file unzipping techniques.

class satpy.tests.reader_tests.test_utils.TestSunEarthDistanceCorrection[source]

Bases: object

Tests for applying Sun-Earth distance correction to reflectance.

setup_method()[source]: Create input / output arrays for the tests.

test_apply_sunearth_corr()[source]: Test the correction of reflectances with sun-earth distance.

test_get_utc_time()[source]: Test the retrieval of scene time from a dataset.

test_remove_sunearth_corr()[source]: Test the removal of the sun-earth distance correction.

satpy.tests.reader_tests.test_utils.test_generic_open_binary(tmp_path, data, filename, mode)[source]: Test the bz2 file unzipping context manager using dummy binary data.
