Question

Actually I don’t see what I am doing wrong here but I guess it is a very simple and basic problem:

Module 1 called Widget17_Sorter.py:

class Widget17_Sorter(object):

    def get_data_from_database(self, database_name, user, password, host ):
        ...do stuff here...

Module 2 called Test_Widget17_Sorter.py (actually a unit test)

import Widget17_Sorter

class Test(unittest.TestCase):

    ...do some other stuff here...

    def test_get_data_from_database(self):
        sorter = Widget17_Sorter.Widget17_Sorter()
        raw_data = sorter.get_data_from_database( self.database_name, 
                                    self.user, self.password, self.host )

When executing the test I get the following error message:

ERROR: test_get_data_from_database (__main__.Test)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "TestWidget17_Sorter.py", line 50, in test_get_data_from_database
    raw_data = sorter.get_data_from_database( self.database_name,
AttributeError: 'Widget17_Sorter' object has no attribute 'get_data_from_database'

Why?

Answer 1

Try importing this way:

from Widget17_Sorter import Widget17_Sorter
...
my_widget = Widget17_Sorter(...)
my_widget.get_data_from_database(...)

…and put both scripts in the same folder…
