How to use _normalize_file_payloads method in Playwright Python

The best way to do it is using playwright docker image as base image, then you won't need to install its dependencies. Take a look to the documentation here: https://playwright.dev/docs/docker

https://github.com/microsoft/playwright-python/issues/1622 :

Sounds like we need to upgrade to Greenlet v2 for that.

Step 1: make sure you're in Linux Container in Docker.

Step 2: Go to C:\Users\[User Name]\.docker\config.json Replace credsStore to credStore

Step 3: create Dockerfile, .dockerignore and docker-compose.yml file

Step 4: docker-compose format.

version: "3.9"
services:
frontend:
build: .
ports:
  - "8000:80"
backend:
image: "mcr.microsoft.com/mssql/server"
environment:
  SA_PASSWORD: "Docker123!"
  ACCEPT_EULA: "Y"
ports:
  - "1440:1433"

try to use sam ports as I mentioned here. User = sa, Database = master It will run perfectly fine. IA.

Not sure exactly if by "browser to show up" you refer at the fact that you need the browser to not run in headless mode.

There are two possible ways:

1. Install Playwright Test for VSCode as suggest by @MingJie-MSFT. You'll have a Show browser checkbox there in case you want to run your tests headless or not
2. In the config file, for use, add:

headless: false

Example for both options

I ran into this problem as well where my test would run in headed mode but not headless mode. I had a window of Chromium open when trying to run my test and it will fail. Once I closed all Chromium windows it worked in headless mode.

The accepted answer does not work with the newer versions of Playwright. (Thanks @576i for pointing this out)

Here is the Python code that works with the newer versions (tested with version 1.5):

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.launch()
    page = browser.new_page()
    page.goto('http://whatsmyuseragent.org/')
    ua = page.query_selector(".user-agent");
    print(ua.inner_html())
    browser.close()

To get only the text, use the inner_text() function.

print(ua.inner_text())

I found out that the problem was i was trying to close the context before closing the page first, and that was the thing which raises unhandleable exceptions. The solution is replacing the close_playwright() function with this:

def close_playwright():

    page.close()
    context.close()
    browser.close()
    playwright.dispose()

Thanks for the question. I'll share what's possible today, and we would be happy to make changes if you could share your scenario as an issue on playwright-python.

playwright-python can work with environment variables like outlined in the linked doc. For example, you can set environment variable for PLAYWRIGHT_BROWSERS_PATH to specify a custom location for your browser binaries.

It is recommended to use Playwright against bundled browser binaries, since Playwright can often depend on browser-side changes that might not be available in older versions. These browser-side changes are done with the intent to improve execution reliability and breadth of Playwright capabilities.

In case you do want to use Playwright against a non-bundled browser binary, you can set the executablePath while launching a browser. For example, the script below launches Edge instead of the bundled Chromium binary.

Python 3.8.0 (default, Sep 21 2020, 12:25:40)
[Clang 12.0.0 (clang-1200.0.32.2)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from playwright import sync_playwright
>>> pw = sync_playwright().start()
>>> browser = pw.chromium.launch(headless=False, executablePath='/Applications/Microsoft Edge Dev.app/Contents/MacOS/Microsoft Edge Dev')

We do not provide browser specific packages like playwright-chromium for Python today, but we are happy to collect feedback on it and make changes.

What dialog.accept() does is to accept (click OK) the dialog. page.click("OK") only works with DOM (HTML) elements, not with browser dialogs.
