How to use test_framenavigated_when_navigating_on_anchor_urls method in Playwright Python

You can do:

hrefs_of_page = page.eval_on_selector_all("a[href^='/wiki/']", "elements => elements.map(element => element.href)")

which should work for your use-case. This will lookup for all the link tags which have a href attribute which starts with /wiki. Then on the browser side JavaScript gets evaluated which maps from an array of elements to the href attribute so a string array gets returned on the Python side.

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 have to use inner_text for this:

email = page.locator.inner_text("#cphMain_hlOrgInboundEmail")
print(email)

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.

afaik, playwright uses a virtual keyboard and does not exactly send the same signal as a real keyboard to the browser application.

consider going native and using something closer to kernel like pyautogui, after you've focused you window:

import pyautogui
pyautogui.press('f5')

This works for me, is your element maybe no textarea or prevents new lines with a custom onChange handler in e.g. React?

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    for browser_type in [p.chromium, p.firefox, p.webkit]:
        browser = browser_type.launch()
        page = browser.new_page()
        page.set_content("""<textarea id="foobar"></textarea>""")
        page.fill("#foobar", "foo\nbar")
        page.screenshot(path="example.png")
        browser.close()

Replace your breakpoint by auth_page.pause()

You can learn more about the api page.pause() here.

as mentioned in https://github.com/microsoft/playwright-python/issues/480

Jupyter notebook uses asyncio event loop, so you should use async api.

from playwright.async_api import async_playwright

playwright = await async_playwright().start()
browser = await playwright.chromium.launch(headless = False)
page = await browser.new_page()

await page.goto("http://whatsmyuseragent.org/")

# await page.screenshot(path="example.png")
# await browser.close()
# await playwright.stop()

If you use sync API, it will throw an Error like this:

from playwright.sync_api import sync_playwright
playwright = sync_playwright().start()

'''
Error: It looks like you are using Playwright Sync API inside the asyncio loop.
Please use the Async API instead.
'''
