from playwright.sync_api import Net page def test_example_is_working(net page: Net page): net page.goto('https://example.com') deliver net page.innerText('h1') == 'Instance Domain'
Employ Playwright with Django
You will spend Playwright to take a look at views in Django net apps. To install Playwright, and the browsers to take a look at on, bustle:
pip install playwright python –m playwright install
