How do you generate dynamic (parameterized) unit tests in python?

Question

I have some kind of test data and want to create a unit test for each item. My first idea was to do it like this:

import unittest

l = [[\"foo\", \"a\", \"a\

You can use nose-ittr plugin (pip install nose-ittr).

It's very easy to integrate with existing tests, minimal changes (if any) are required. It also supports nose multiprocessing plugin.

Not that you can also have a customize setup function per test.

@ittr(number=[1, 2, 3, 4])   
def test_even(self):   
    assert_equal(self.number % 2, 0)

It is also possible to pass nosetest parameters like with their build-in plugin attrib, this way you can run only a specific test with specific parameter:

nosetest -a number=2
