Playwright Web Automation Testing Using Python

In this blogpost, we will discuss how to run Playwright automation tests using Python programming language on Visual Studio code IDE.

I’ll put the post in three points as shown below:

1. Set Up
2. Test Automation Framework with Playwright and Python
3. Integrate Automation Tests with CI

1. Set Up: 

Do the following installations on your Mac.

• Install Node: Run the command "brew install node" on your terminal. 
• Install Python3: Go to Python3-Download

Check python3 version 

Check your path of python3 : Run the command "which -a python3"

Install Playwright & pytest

pip install pytest playwright

Install Playwright Browsers

playwright install

Create and Activate Virtual Environment

python3 -m venv venv

Install Pytest Plugin for Playwright Fixtures

pip install pytest-playwright

2. Test Automation Framework with Playwright and Python: 

A basic boilerplate code using Page Object Design framework is created for this post and the folder structure, page objects, pages, tests and test report are shown below.

The Folder structure looks like this

 Page Objects:  The locators used for the tests. For ex: Login page locators below.

The framework is developed using Page Object Design Pattern.

 Pages : The individual web pages used for the test.

 base_page.py - Contains all the web actions used by the tests and will  

 be inherited by the the other pages like login page, cart page, Inventory  

 page etc..

login_page.py

Test:

test_end_to_end.py

The test will call the needed pages and in-turn in the pages will inherit the base page functions/methods to perform the web actions. Assertions are checked and put in place.

Run the Tests locally:

For all tests : pytest --html=reports/report.html

For specific test : pytest tests/test_login.py -s -v

Test Report: 

From your Report Folder 'reports/report.html'

3. Integrate Automation Tests with CI 

GitHub Actions:- 

Run the Tests on GitHub Actions 

Pipeline:

https://github.com/JayKishoreDuvvuri/Playwright-Python/actions

Create a folder .github/workflows and inside this folder create a yml file with name "playwright.yml" file as shown below

Go to GitHub Actions and check the run

Click on the first one

Click on test as shown below

Check the test report!

Save to your desktop to view the report.

Open the report.html file

For Test code reference, Please see the GitHub repo: https://github.com/JayKishoreDuvvuri/Playwright-Python

Happy Automation Testing Guys :)!
