Read the unit testing framework section of the Python Library Reference .
A basic example from the documentation:
import random
import unittest
class TestSequenceFunctions(unittest.TestCase):
def setUp(self):
self.seq = range(10)
def testshuffle(self):
# make sure the shuffled sequence does not lose any elements
random.shuffle(self.seq)
self.seq.sort()
self.assertEqual(self.seq, range(10))
def testchoice(self):
element = random.choice(self.seq)
self.assert_(element in self.seq)
def testsample(self):
self.assertRaises(ValueError, random.sample, self.seq, 20)
for element in random.sample(self.seq, 5):
self.assert_(element in self.seq)
if __name__ == '__main__':
unittest.main()
It's probably best to start off with the given unittest
example. Some standard best practices:
tests
folder at the root of your project. test
. test
. When you've become comfortable with unittest
(and it shouldn't take long), there are some nice extensions to it that will make life easier as your tests grow in number and scope:
