nose-ittr

nose extension for supporting parametrized testing.

Allows developer to run the same test over and over again using different values

Main Features:

• Very easy to integrate with existing tests
• Saves a lot of boilerplate code, and code replication
• Work with all nose plugins (including multiprocessing)
• Customize setup per test, by using this package built-in nose plugin setup-ittr

Installation:

pip install nose_ittr

Basic usage:

import math

from nose.tools import assert_equal, assert_not_equal
from nose_ittr import IttrMultiplier, ittr

class TestFoo(object):

    __metaclass__ = IttrMultiplier

    def setup(self):
        if hasattr(self, 'value'):
            self.value += 3

    def teardown(self):
        pass

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

    @ittr(numerator=[15, 6], denominator=[2, 3])
    def test_no_remainder(self):
        assert_equal(self.numerator % self.denominator, 0)

    @ittr(value=[4, 14])
    def test_prime_with_custom_setup(self):
        for i in range(3, int(math.sqrt(self.value))):
            assert_not_equal(self.value % i, 0)

nosetests --with-setup-ittr [for setup customization support]

result:

TestFoo.test_even_1 ... FAIL
TestFoo.test_even_2 ... .ok
TestFoo.test_even_3 ... FAIL
TestFoo.test_even_4 ... .ok
TestFoo.test_no_remainder_2_6 ... .ok
TestFoo.test_no_remainder_2_15 ... FAIL
TestFoo.test_no_remainder_3_6 ... .ok
TestFoo.test_no_remainder_3_15 ... .ok
TestFoo.test_prime_with_custom_setup_14 ... ok
TestFoo.test_prime_with_custom_setup_4 ... ok

Notes:

• Doesn't affect test docstring if used with -v parameter.

To change the docstring printout based on the varibales passed to test, use the plugin nose-docstring-modifier.
