class satpy.tests.reader_tests.test_viirs_sdr.TestAggrVIIRSSDRReader(methodName='runTest')

Bases: TestCase

Test VIIRS SDR Reader.

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.

_classSetupFailed = False

_class_cleanups = []

setUp()

Wrap HDF5 file handler with our own fake handler.

tearDown()

Stop wrapping the HDF5 file handler.

test_bounding_box()

Test bounding box.

yaml_file = 'viirs_sdr.yaml'

class satpy.tests.reader_tests.test_viirs_sdr.TestShortAggrVIIRSSDRReader(methodName='runTest')

Bases: TestCase

Test VIIRS SDR Reader with a file that has truncated granules.

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.

_classSetupFailed = False

_class_cleanups = []

setUp()

Wrap HDF5 file handler with our own fake handler.

tearDown()

Stop wrapping the HDF5 file handler.

test_load_truncated_band()

Test loading a single truncated band.

yaml_file = 'viirs_sdr.yaml'

class satpy.tests.reader_tests.test_viirs_sdr.TestVIIRSSDRReader(methodName='runTest')

Bases: TestCase

Test VIIRS SDR Reader.

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.

_assert_reflectance_properties(data_arr, num_scans=16, with_area=True)

_classSetupFailed = False

_class_cleanups = []

setUp()

Wrap HDF5 file handler with our own fake handler.

tearDown()

Stop wrapping the HDF5 file handler.

test_init()

Test basic init with no extra parameters.

test_init_end_time_beyond()

Test basic init with end_time before the provided files.

test_init_start_end_time()

Test basic init with end_time before the provided files.

test_init_start_time_beyond()

Test basic init with start_time after the provided files.

test_init_start_time_is_nodate()

Test basic init with start_time being set to the no-date 1/1-1958.

test_load_all_i_bts()

Load all I band brightness temperatures.

test_load_all_i_radiances()

Load all I band radiances.

test_load_all_i_reflectances_provided_geo()

Load all I band reflectances with geo files provided.

test_load_all_m_bts()

Load all M band brightness temperatures.

test_load_all_m_radiances()

Load all M band radiances.

test_load_all_m_reflectances_find_geo()

Load all M band reflectances with geo files not specified but existing.

test_load_all_m_reflectances_no_geo()

Load all M band reflectances with no geo files provided.

test_load_all_m_reflectances_provided_geo()

Load all M band reflectances with geo files provided.

test_load_all_m_reflectances_use_nontc()

Load all M band reflectances but use non-TC geolocation.

test_load_all_m_reflectances_use_nontc2()

Load all M band reflectances but use non-TC geolocation because TC isn’t available.

test_load_dnb()

Load DNB dataset.

test_load_dnb_no_factors()

Load DNB dataset with no provided scale factors.

test_load_dnb_sza_no_factors()
