How to check for element existence without getting an error in Playwright

The only way I found is wrap the goto inside a try-except block

Content of main.py

from playwright.sync_api import Playwright, sync_playwright, expect

with sync_playwright() as p:
    #We define the browser, the context and the page
    browser = p.chromium.launch(headless=False)
    context = browser.new_context()
    page = browser.new_page()
    with page.expect_download() as download_info:
        #If we navigate without try, it will throw an exception and it will stop our script, so, we wrap it inside a try except block
        try:
            page.goto("https://manueltgomes.com/wp-content/uploads/2021/09/ParseHTMLLInks_1_0_0_1.zip")
        except:
            pass
    download = download_info.value
    download.save_as(f"./{download.suggested_filename}")
    context.close()
    browser.close()

Then just run python3 main.py

The file will be saved in the same path of the main.py file

You can access the href in an almost similar way to that of selenium.

element_handle = page.locator("//a")
link = element_handle.get_attribute('href')

PLAYWRITH_BROWSERS_PATH=0

Please make sure your above configuration was correct. There are some spelling mistakes in the settings. Its like PLAYWRIGHT_BROWSERS_PATH = 0

In your local.settings.json it should be

{

"IsEncrypted": false,

    "Values": {
    
        "AzureWebJobsStorage": "",
        
        "FUNCTIONS_WORKER_RUNTIME": "python",
        
        "PLAYWRIGHT_BROWSERS_PATH": "0"
    
    }

}

And In your requirement.txt file it should be

azure-functions
playwright==1.18.0

here we can see the playwright running in local as well as azure after deployment Local: enter image description here

while totalRequests < 100:
    for thread in range(numberOfThreads):

            t.start()
            totalRequests += 1

https://stackoverflow.com/questions/74631728/how-to-test-a-single-get-request-in-parallel-for-specified-count

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)

https://stackoverflow.com/questions/70770526/how-to-quickly-find-out-if-an-element-exists-in-a-page-or-not-using-playwright

You could use something called element_handle.is_visible() from here.

your code should look something like below.

href_element = page.query_selector("a")
href_element.is_visible()
