Simple Python nose testing example

mymath.py

from __future__ import division

def add(num1, num2):
    assert type(num1) == int or type(num1) == float
    assert type(num2) == int or type(num2) == float
    return num1 + num2

def divide(numerator, denominator):
    return numerator / denominator

test_mymath.py

from mymath import *
import nose

def test_add_integers():
    assert add(5, 3) == 8
    
def test_add_integers_zero():
    assert add(3, 0) == 3
    
def test_add_floats():
    assert add(1.5, 2.5) == 4
    
def test_add_strings():
    nose.tools.assert_raises(AssertionError, add, 'paul', 'carol')
    
def test_divide_integers_even():
    assert divide(2, 10) == 0.2
    
def test_divide_integers_repetant():
    nose.tools.assert_almost_equal(divide(1, 3), 0.33333333, 7)
