How to write test cases for a init function by Unit test in python?

[Larz60+]

you have:

class DataSinkConfig():
    DEFAULT_ENTRIES_TABLE = 'entries'
    DEFAULT_OUTLIERS_TABLE = 'outliers'
    DEFAULT_OUTLIERCAUSES_TABLE = 'outlier_causes'
 
    # Note
    def __init__(self, dbconf):
 
        insopt = dbconf.get('insopt')
        if insopt is None:
            self.entries_table_name = self.DEFAULT_ENTRIES_TABLE
            self.outliers_table_name = self.DEFAULT_OUTLIERS_TABLE
            self.outlier_causes_table_name = self.DEFAULT_OUTLIERCAUSES_TABLE

why not just?:

class DataSinkConfig():
    def __init__(self, dbconf):
 
        insopt = dbconf.get('insopt')
        if insopt is None:
            self.entries_table_name = 'entries'
            self.outliers_table_name = 'outliers'
            self.outlier_causes_table_name = 'outlier_causes'
