v1.18.0

API Testing

Playwright for Python 1.18 introduces new API Testing that lets you send requests to the server directly from Python!
Now you can:

• test your server API
• prepare server side state before visiting the web application in a test
• validate server side post-conditions after running some actions in the browser

To do a request on behalf of Playwright's Page, use new page.request API:

# Do a GET request on behalf of page
res = page.request.get("http://example.com/foo.json")

Web-First Assertions

Playwright for Python 1.18 introduces Web-First Assertions.

Consider the following example:

from playwright.sync_api import Page, expect

def test_status_becomes_submitted(page: Page) -> None:
    # ..
    page.click("#submit-button")
    expect(page.locator(".status")).to_have_text("Submitted")

Playwright will be re-testing the node with the selector .status until
fetched Node has the "Submitted" text. It will be re-fetching the node and
checking it over and over, until the condition is met or until the timeout is
reached. You can pass this timeout as an option.
