Python Scripting - Automation

Python Unittest | Pyunit

Python Unit Test Module or PyUnit is a unit test framework similar to Junit .The unittest module provides classes that make it easy to support these qualities for a set of tests. Helps in creating easy Automation and handling big codes !

How to install :

Pip install unittest   ---- Step 1

Unit Test Features :

• supports test automation
• sharing of setup and shutdown code for tests
• aggregation of tests into collections
• independence of the tests from the reporting framework

Basic Functions in  UnitTest :

test fixture

A test fixture represents the preparation needed to perform one or more tests, and any associate cleanup actions. This may involve, for example, creating temporary or proxy databases, directories, or starting a server process.

test case

A test case is the smallest unit of testing. It checks for a specific response to a particular set of inputs. unittest provides a base class, TestCase, which may be used to create new test cases.

test suite

A test suite is a collection of test cases, test suites, or both. It is used to aggregate tests that should be executed together.

test runner

A test runner is a component which orchestrates the execution of tests and provides the outcome to the user. The runner may use a graphical interface, a textual interface, or return a special value to indicate the results of executing the tests.

Sample code :

------------------------------------------------Importing Libraries------------------------------------

import unittest

from selenium import webdriver

from selenium.webdriver.common.keys import Keys

from selenium.common.exceptions import TimeoutException

from pynput.keyboard import Key, Controller

def Keyboard_press_release():

    keyboard.press(Key.ctrl)

    keyboard.press(Key.tab)

    keyboard.release(Key.ctrl)

    keyboard.release(Key.tab)        

 ------------------------------------------Main Class --------------------------------------------------------------

class AdminPortalWorkflowTest(unittest.TestCase):

------------------------------------------Test case 1 --------------------------------------------------------------

    def test_Launch(self):

        self.driver = webdriver.Chrome('C:\Python27\Scripts\chromedriver.exe')       

        global keyboard

        keyboard = Controller()

        driver = self.driver

        driver.get("https://www.google.com")

        time.sleep(5) 

        Keyboard_press_release()

----------------------------------------Test case 2 ----------------------------------------------------------------                 

    def test_Check(self):

        print "func starts ..."     

----------------Created a Suite which combines Testcase 1and 2 and returns a List -----------------

           

def suite():

    suite = unittest.TestSuite()

    suite.addTest(AdminPortalWorkflowTest('test_Launch'))

    suite.addTest(AdminPortalWorkflowTest('test_Check'))

    return suite                                   

-----------------------------------------Main Function ------------------------------------------------------------

if __name__ == '__main__':

--------------------------------- Calling Suite which runs all test  --------------------------------------------

unittest.TextTestRunner(verbosity=2).run(suite())
