Is there a 'decent' way in unittest to check the equality of the contents of two iterable objects? I am using a lot of tuples, lists and numpy arrays and I usually only want to test for the contents and not for the type. Currently I am simply casting the type:
self.assertEqual (tuple (self.numpy_data), tuple (self.reference_list)) I used this list comprehension a while ago:
[self.assertEqual (*x) for x in zip(self.numpy_data, self.reference_list)] But this solution seems a bit inferior to the typecast because it only prints single values if it fails and also it does not fail for different lengths of reference and data (due to the zip-function).

The command to run the tests is python -m unittest filename.py . In our case, the command to run the tests is python -m unittest test_utils.py .
First you need to create a test file. Then import the unittest module, define the testing class that inherits from unittest. TestCase, and lastly, write a series of methods to test all the cases of your function's behavior. First, you need to import a unittest and the function you want to test, formatted_name() .
An exception object is created when a Python script raises an exception. If the script explicitly doesn't handle the exception, the program will be forced to terminate abruptly.

You can always add your own assertion methods to your TestCase class:
def assertSequenceEqual(self, it1, it2): self.assertEqual(tuple(it1), tuple(it2)) or take a look at how 2.7 defined it: http://hg.python.org/cpython/file/14cafb8d1480/Lib/unittest/case.py#l621
