Local Modules

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()

unittest framework 

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...."

if __name__ == '__main__':
    unittest.main()
