Nose unittest simple example

Here we will test helloWorld.py using nose
All source code are available on github

# testHelloWorld.py
from nose import with_setup

__author__ = 'AbuZahedJony'

from helloWorld import add_two_num
from helloWorld import multi_two_num

def m_setup():
    print "\nRun SETUP"

def m_teardown():
    print "Run TEAR-DOWN"

@with_setup(m_setup, m_teardown)
def test_add_num():
    print "Running test ADD"
    assert add_two_num(2, 3) == 5
    assert add_two_num(-2, 3) == 1
    assert add_two_num(-2, -3) == -5

@with_setup(m_setup, m_teardown)
def test_multi_num():
    print "Running test MULTI"
    assert multi_two_num(2, 3) == 6
    assert multi_two_num(-2, 3) == -6
    assert multi_two_num(-2, -3) == 6

RUN: nosetests -s testHelloWorld.py

Output:

Run SETUP
Running test ADD
Run TEAR-DOWN
.
Run SETUP
