How to quickly find out if an element exists in a page or not using playwright

Closing actual popups

I think browser.once("targetcreated", ...) as described in this issue https://stackoverflow.com/a/57246544/2202112 could be something that you are looking for.

It allows you to setup a callback on newly created targets.

For reference, see puppeteer docs on "targetcreated"

Closing modals

Find the selector for the button that dismisses the modal, for example .button-close or .button-dismiss.
Use the page.click(selector, [options]) method to click the button before continuing further scraping

Not sure about Colab, but in a normal Jupyter notebook you do:

import nest_asyncio
nest_asyncio.apply()

Install with pip install nest-asyncio, and then you can run async stuff in a notebook.

Edit: You are also trying to run a GUI instance of Chrome, with that headless=False - change that to headless=True, Colab doens't run with a GUI.

That happens because your webpage did not load totally, you can set a timeout like:

page.goto('https://www.zameen.com/', timeout=100000)

Or you can even don't wait till your page is loaded and just navigate without waiting the page to be fully loaded with timeout=0

page.goto('https://www.zameen.com/', timeout=0)

https://stackoverflow.com/questions/74746473/playwright-is-timing-out-before-running-page-pause

After trying many different variants, I guessed a working syntax

handle.selectOption({"label": "Banana"})

https://stackoverflow.com/questions/64306147/using-playwright-for-python-how-do-i-select-an-option-from-a-drop-down-list

You can use one of those options :

const element = await page.$$("text='element'");
if (element) {
    // ...
}

const element = await page.$$("text='element'");
if (element.length) {
    // ...
}

await expect(page.locator(".MyClass")).toHaveCount(0)

How To Run Your First Playwright Test On Cloud

One of the biggest problems I’ve faced when building a test suite is not the writing of the tests but the execution. How can I execute 100s or 1000s of tests in parallel?If I try that on my local machine, it would probably catch fire – so we need a remote environment to send these to.
