I'm getting an error using playwright nth-match

I see what the problem here is. It does have to do with pyautogui and playwright not functioning together correctly. I tried searching around to find how to actually get the current mouse position with playwright, but I did not find anything.

So, here is my conclusion:

How did I figure out the problem, and what actually is the problem?

The problem here is that pyautogui actually controls the computer's mouse in this case. It seems like playwright only controls that of the browser. If you add a time.sleep(10) (In order to actually see if the cursor has changed position and to have time to move the cursor at a different position) at the end of the function like so:

def test_simple_move():
    mouse_start_position = pyautogui.position()
    print(mouse_start_position)
    
    with sync_playwright() as playwright:
        browser = playwright.chromium.launch(headless=False, slow_mo=10)
        page = browser.new_page()
        page.goto(r"http://www.uitestingplayground.com/")
        page.mouse.move(100,400)
        mouse_final_position = pyautogui.position()
        print(mouse_final_position)

        time.sleep(10)

You will then see that the actual cursor does not move. It seems like what playwright is doing here is just moving a "virtual" cursor in its browser. In fact, what I did to prove this was:

  1. Launch the code
  2. While the delay of 10 seconds is going, move the cursor to another point on the screen.
  3. Wait for the code to finish.
  4. You will now see how the points are different. Here are my points
