python - nose config

0 votes

I'm using nose to generate and run some tests not for python code, but for an html repository. I know this isn't the typical way to use nose, and so I'm asking here if the following code smells wrong.

I pass some args with the testconfig plugin and run a class setup method one time to get some information from a database. Then the tests get generated and run. During the run, a database is updated with the result. That is an intentional side-effect of running the that okay or something that should never be done?

I've shortened the actual code to make it readable, but the main thing is the setup (setting class vars), the test generator, and the actual test (plus the database update):

class HtmlTester(object):
 Run this setup method once before tests begin.
 Reads from tconfig args to get document from database.
 def setup_class(cls):
 name = tconfig['name']
 language = tconfig.get('language', 'en')
 report = db.conn({'name':name, 

 def test_images(self):
 for image in['images']:
 yield (self.check_image, image)

 def check_image(self, image):
 True if image can be read, otherwise False
 r = False
 if get_imagesize(image):
 p = ImageFile.Parser()
 except IOError:
 r = False
 r = True{'image':image, 'result':r, 
 'language': self.language})

 if __name__ == '__main__':
 args = sys.argv[:1] + ['--tc=name:mybook', 
 '--tc=language:en' ] + sys.argv[1:]

This is complex enough that I wonder if the above approach is correct.

I'm working on association analysis on my dataset that consist majorly of categorical features and I'm using Cramers' V and Theils U statistical measures for showcasing the association metrics.

I have 2 questions related to the same :

If there are some missing values in some of the columns in my dataset, how should I handle them while calculation Cramers' V and theils u metrics? Shall I replace the missing value with some dummy value?
Note: I'm using python's python library for the calculation of both the metrics.

dython.nominal.cramers_v(data[field1],data[field2]) and dython.nominal.theils_u(data[field1],data[field2])

If I have a column name like "Task Creation Date" that consists of DateTime values. How can I include this field as part of my association analysis? Does Cramers' V and Theils U consider date values as input ? or some conversion is required?

Any help would be much appreciated.
