nose expansion for supporting parametrized testing
Project description
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.
