Components of Unit Testing

Test fixture
Test case
Test suite
Test runner

Test Fixture

Data creation
Test configuration update
Environment variable update

Test Case

Test case is logical program to test a particular unit

Text Assertion

Test Assertion is a statement that decide the result of a particular test.

Test Suite

A collection of Test Cases is called Test Suite.

Test Runner

Test Runner is a program or framework that helps to execute the Test Suites.

unittest framework

import unittest

class <test_sute>(unittest.TestCase):

    def test_<test_case>(self):
        # Assertion
        self.assertEqual('foo'.upper(), 'FOO')

unittest framework

import unittest

class TestStringMethods(unittest.TestCase):

    def test_upper(self):
        self.assertEqual('foo'.upper(), 'TOO')

    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()

import unittest

class Person(object):
    def set_name(self,name):
        self.name = name

class TestCaseFixture(unittest.TestCase):
    person = None
    def setUp(self):
        print "SETUP CALLING..."
        TestCaseFixture.person = Person()
        TestCaseFixture.person.set_name("Alivenet")

    def test_name(self):
        self.assertEqual(TestCaseFixture.person.name, 'Alivenet')
    
    def tearDown(self):
        print "TEAR DOWN CALLIN...."
