python unit testing library code example
Example 1: unittest module in python
import unittest
class TestStringMethods(unittest.TestCase):
def test_upper(self):
self.assertEqual('foo'.upper(), 'FOO')
def test_isupper(self):
self.assertTrue('FOO'.isupper())
self.assertFalse('Foo'.isupper())
def test_split(self):
s = 'hello world'
self.assertEqual(s.split(), ['hello', 'world'])
# check that s.split fails when the separator is not a string
with self.assertRaises(TypeError):
s.split(2)
if __name__ == '__main__':
unittest.main()
Example 2: python unittest setUpClass
class MyUnitTest(unittest.TestCase):
@classmethod
def setUpClass(cls):
do_something_expensive_for_all_sets_of_tests()
class MyFirstSetOfTests(MyUnitTest):
@classmethod
def setUpClass(cls):
super(MyFirstSetOfTests, cls).setUpClass()
do_something_expensive_for_just_these_first_tests()
Example 3: self.assertequal python
'''
In other words, assertEquals is a function to check if two variables are equal, for purposes of automated testing:
'''
def assertEquals(var1, var2):
if var1 == var2:
return True
else:
return False
