Nose decorator for parameterized testing

Project description

Nose. It’s got test generators. But they kind of suck, because:

  • They often require a second function

  • They make it difficult to separate the data from the test

  • They don’t work with subclases of unittest.TestCase

But nose-parameterized fixes that:

$ cat test_math.py
from nose.tools import assert_equal
from nose_parameterized import parameterized

import unittest
import math

@parameterized([
    (2, 2, 4),
    (2, 3, 8),
    (1, 9, 1),
    (0, 9, 0),
])
def test_pow(base, exponent, expected):
    assert_equal(math.pow(base, exponent), expected)


class TestMathUnitTest(unittest.TestCase):
    @parameterized.expand([
        (-1.5, -2.0),
        (1.0, 1.0),
        (1.6, 1),
    ])
    def test_floor(self, input, expected):
        assert_equal(math.floor(input), expected)
$ nosetests -v test_math.py
test_math.test_pow(2, 2, 4) ... ok
test_math.test_pow(2, 3, 8) ... ok
test_math.test_pow(1, 9, 1) ... ok
test_math.test_pow(0, 9, 0) ... ok
test_floor_0 (test_math.TestMathUnitTest) ... ok
test_floor_1 (test_math.TestMathUnitTest) ... ok
test_floor_2 (test_math.TestMathUnitTest) ... ok
