How to use run_as_sync method in Playwright Python

Reading your question I understand that your problem is not the download itself, your problem is the way of clicking the link that you need.

From that moment, you have to options:

1 - You know the date (exact text):

date = "2022-09-26"
with page.expect_download() as download_info:
    page.locator(f"//a[text()='{date}_TEST.zip']").click()
    download = download_info.value
    page.wait_for_url("http://192.xx")
    download_filepath = os.path.join(download_path, suggested_filename)
    download.save_as(download_filepath)
    context.close()
    browser.close()

As you can see you can use f"..{}.." for your locator string in order to use some vars for the locator, basically a locator is a string.

Of course you should know the date before, in my example is hardcoded.

2 - You don't know the date (Contains text):

with page.expect_download() as download_info:
    page.locator(f"//a[contains(text(),'_TEST.zip')]").click()
    download = download_info.value
    page.wait_for_url("http://192.xx")
    download_filepath = os.path.join(download_path, suggested_filename)
    download.save_as(download_filepath)
    context.close()
    browser.close()

And being honest, I think the line page.wait_for_url("http://192.xx") is not needed. Playwright will wait for your download, actually you don't need to wait for the url, I think.

For my examples I used selector with Xpath.

I have come up with a solution in Node js puppeteer and I think it work the same way in python. As far as why the button isn't being pressed, I have no idea. But, what does work is entering an address and then clicking the first address suggestion.

Here is my code:

const puppeteer = require('puppeteer');
async function start(){
    const browser = await puppeteer.launch()
    const page = await browser.newPage()
    await page.goto("https://www.ubereats.com/ca")
    await page.type("#location-typeahead-home-input", "Address")
    await page.waitForSelector('#location-typeahead-home-item-0');
    await page.click("#location-typeahead-home-item-0")
    await page.waitForNavigation()

    console.log(page.url())
    await browser.close()
}

start()

Doing something similar for a project of mine, this is how I would do it.

from playwright.sync_api import sync_playwright

posts = ['https://playwright.dev/','https://playwright.dev/python/',]

def scrap_post_info(context, post):
    page = context.new_page()
    page.goto(post)
    print(page.title())
    # do whatever scraping you need to
    page.close()

with sync_playwright() as p:
    browser = p.chromium.launch()
    context = browser.new_context()
    for post in posts:
        scrap_post_info(context, post)
        # some time delay

browser.close()

Thing is the code snippet from the playwright docs is more about opening a new page after clicking a link on an existing page. Since you already have the urls ready, you can just visit each page one by one, and do your scraping.

Another way is to simply use the getAttribute() method of the elementHandle to retrieve the value:

handle = page.querySelector('//input[starts-with(@name, "Counter")]')
value = handle.getAttribute("value")

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.

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.

You can use the not_be_visible expect assertion for this.

expect('element CSS here').not_to_be_visible()

By default expect assertions have a 5 second timeout, in case you want to increase the timeout, you can do like this:

expect('element CSS here').not_to_be_visible(timeout=7000)

You should follow the Page Object Model Architecture: https://playwright.dev/python/docs/pom

Example of project

conftest.py
pom/
--login/
----login_page.py --> In this file we will have all selectors for login page and the basic functions for each element, like fill_user, fill_password, click_login_button etc.
--search/
----search_page.py --> In this file we will have all selectors for search page and the basic functions for each element, like fill_search_bar, click_search_button etc.
tests/
--login/
----test_login.py --> In this file we will use the methods that login_page.py contains like (fill_user, fill_password, click_login_button)
--search/
---- test_search.py --> In this file we will use the methods that login_page.py contains and methods that search_page.py contains (fill_search_bar, click_search_button)

Chrome can't launch itself with a User Profile folder, it must launch from a User Data folder. If you want a specific profile, you can set a profile as your default Chrome profile and then copy the new User Data folder elsewhere for your application (or use original User Data folder).
