Python - unittest

@Python

Up to 2.7, use unittest2 since it's got more assert tests than unittest (they were all backported from the 2.7 release).

Running tests


::

python -m unittest discover -s project_directory -p '*_test.py'

Example


.. code-block:: python
import random
import unittest

class TestSequenceFunctions(unittest.TestCase):

def setUp(self):
self.seq = range(10)

def test_shuffle(self):
# make sure the shuffled sequence does not lose any elements
random.shuffle(self.seq)
self.seq.sort()
self.assertEqual(self.seq, range(10))

# should raise an exception for an immutable sequence
self.assertRaises(TypeError, random.shuffle, (1,2,3))

def test_choice(self):
element = random.choice(self.seq)
self.assertTrue(element in self.seq)

def test_sample(self):
with self.assertRaises(ValueError):
random.sample(self.seq, 20)
for element in random.sample(self.seq, 5):
self.assertTrue(element in self.seq)
