How to use test_should_isolate_contexts method in Playwright Python

You do not need to save the image to a file at all (cmp. screenshot documentation), but instead can simply store it in a variable, like img = page.screenshot(). You can then pass that variable to your REST request. I use the requests module in the example below, the POST request is simplified and may require some additional parameters (depending on your API) or for instance different URLs for the different browser types:

from playwright import sync_playwright
import requests

with sync_playwright() as p:
    for browser_type in [p.chromium, p.firefox, p.webkit]:
        browser = browser_type.launch()
        page = browser.newPage()
        page.goto('https://scrapingant.com/')
        # save screenshot to var
        img = page.screenshot() 
        # pass var directly to your request
        files = {'image': img, 'content-type': 'image/png'}
        requests.post('http://yourresturl.com', files=files)
        browser.close()

If you really wanted to save the image to a temporary file for some reason (which, as I understand your use case, is not really necessary), you could e.g. use the tempfile module and create a named temporary file (cmp. How to use tempfile.NamedTemporaryFile()?):

from playwright import sync_playwright
import tempfile
import requests

tf = tempfile.NamedTemporaryFile(suffix='.png')

with sync_playwright() as p:
    for browser_type in [p.chromium, p.firefox, p.webkit]:
        browser = browser_type.launch()
        page = browser.newPage()
        page.goto('https://scrapingant.com/')
        # save screenshot to temporary file
        page.screenshot(path=tf.name)
        # send request loading temporary file
        requests.post('http://myresturl.com', {'media': open(tf.name, 'rb')})
        browser.close()        

# close temporary file
tf.close()

Does totp need to be a class/static variable? If not, I would make the TwoFactorVerificationPage constructor accept an args parameter:

class TwoFactorVerificationPage():

        def __init__(self, page: Page, args: dict) -> None:
            self.page = page
            self.pin_input = page.locator("[aria-label=\"Two Factor Pin\"]")
            self.verify_button = page.locator('button:has-text("Verify")')
            self.totp = pyotp.TOTP("[USE args HERE]")

        def verify(self) -> None:
            self.pin_input.fill(self.totp.now())
            self.verify_button.click()

Otherwise, I believe you can also set TwoFactorVerificationPage.totp = pyotp.TOTP("[USE command_line_fixtures HERE]") from within test_case.py

Have you tried to download it as Binary package?

Maybe you can go over this libasound.so.2 package page and see if you can download it.

wget https://vault.centos.org/centos/8/AppStream/aarch64/os/Packages/alsa-lib-1.2.5-4.el8.aarch64.rpm

When I searched within apt, ubuntu package tool I don't see anything there

root@21be95fca6e6:/# apt search libasound.so.2
Sorting... Done
Full Text Search... Done

For instance, Vim package would appears like below

root@21be95fca6e6:/# apt search vim           
Sorting... Done
Full Text Search... Done

There is several good practices for creating locators/selectors. Using playwright there is official documentation for each common and unique selector on how-to and what-is doing.

More information in https://playwright.dev/docs/selectors#text-selector

About your case, i would suggest always to use an parent selector for locating an element. When there is a button, try to find its unique parent.

• By id
• By unique class
• Something else unique.

Example:

<dv id=test>
 <button id=continue-test>Continue</button>
</div>

In this case you can use the unique id of the button and not the text. Selector css: #continue-test But if you, don't have an unique identifier for the button you can use the parent and go down to the button. Selector css: #test > button

Matching text using css is not possible, but with XPATH can look like this:

//button[text()="Continue"] 

This selector MATCHES the text using "equals".

Using playwright:

button:has-text("Continue")

Using has-text and quotes - matches the text using equals. If you are using another selector for example text=Continue, this will match all elements that CONTAINS the text "Continue"

All this is explained with example in the official documentation for playwright selectors. That does not mean to not use XPATH to achieve the goals.

CSS selectors are fast but kind of restricted to work with text.

Xpath is quite slower but much more powerful to work in text/parent/child elements etc.

I would suggest always to use an parent element with unique identifier and go down to reach your actual element, which will receive the interaction.

I am not sure if you have solved this yet. I am having a similar problem and I don't understand all the syntax yet. The docs are definitely better for Javascript.

I am able to set extra HTTP headers with this code though:

with sync_playwright() as p:
    browser = p.chromium.launch(headless=True).new_context(ignore_https_errors=True, extra_http_headers={"namex": "romeo"}, user_agent="joe", locale="de-DE", )
                        
    page = browser.new_page()
    page.set_viewport_size({"width": 1600, "height": 1200})
            
    page.goto("http://example.com")
                       
    browser.close()

It means that your object of ScrapyPlaywrightDownloadHandler doesn't have an attribute named browser.

It looks like you're trying to run python -m playwright install as python code rather than a shell command. Try running !python -m playwright install to signal to jupyter that this a shell command rather than python code. Use the ! prefix anytime you need to run a shell command on your environment in jupyter.

import requests
import threading

totalRequests = 0
numberOfThreads = 10
threads = [0] * numberOfThreads


def worker(thread):
    r = requests.get("url")
    threads[thread] = 0  # free thread


while totalRequests < 100:
    for thread in range(numberOfThreads):
        if threads[thread] == 0:
            threads[thread] = 1  # occupy thread
            t = threading.Thread(target=worker, args=(thread,))
            t.start()
            totalRequests += 1

Your locator should look like this. Replace ":" with ">>"

div[class="some-class"]>>nth=3
