Playwright Tutorial , installation > Record tests, Run Tests

Playwright enables reliable end-to-end testing for modern web apps.

1. Installation:

pip install pytest-playwright

Browsers: https://playwright.dev/python/docs/browsers
playwright install #INSTALL default browsers
playwright install --help
Custom browsers: chromium, chromium-headless-shell, chromium-tip-of-tree-headless-shell, chrome, chrome-beta, msedge, msedge-beta, msedge-dev, bidi-chromium, firefox, webkit.
playwright install --with-deps chrome

playwright install # install browsers

2.RECORD TESTS

Run the below command in cmd and do some actions with opened url , Auto code will be generated you can copy that code for use

playwright codegen https://wellguider.com 

3.Tests Run

Create any file with name test_ ie test_example.py  Also need to do this with functions ie test_has_title

def test_has_title():
    with sync_playwright() as p:
        browser = p.firefox.launch(headless=False)  # Set headless=False
        page = browser.new_page()
        page.goto("https://playwright.dev/")
        browser.close()

In current working directory type pytest to runn all tests inside all files, 

pytest # run all files, all test functions auto
pytest test_login.py # only test_login.py
pytest -k test_add_a_todo_item # specific file and function
