How to use set_csp method in Playwright Python

You can use one of those options :

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

or

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

or

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

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

You have to write the page.on("dialog", lambda dialog: dialog.accept()) code before you press on button which is generating the popup. Playwright works with the listner so you should first start listner then click on element which is generating the popup.

page.on("dialog", lambda dialog: dialog.accept())
page.locator(#xyz).click() // Element opening alert window

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

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

this worked for me in java:

Page page = browser.newPage();
Map<String, String> headers = new HashMap<>();
headers.put("user-agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) `enter code here`AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36");
page.setExtraHTTPHeaders(headers );

Just use some condition instead of print method, for example you could check if response contains some key in its json:

def run(playwright):
    chromium = playwright.chromium
    browser = chromium.launch()
    page = browser.new_page()
    # Subscribe to "request" and "response" events.
    page.on("request", lambda request: print(">>", request.method, request.url))
    page.on("response", lambda response: print("<<", response.status, response.url))
    page.goto("https://example.com")
    browser.close()

For Example:

page.on("response", lambda response: response if key in response.body())

There should be waitForResponse for python too, and you could use that.

The sync_api is simply a wrapper around the asyncio_api that abstracts asyncio usage away from you. As such, the capabilities are largely the same, but the async_api may afford some more flexibility in complex scenarios (for example, in previous playwright-python releases the only way to run instances in a multi-threaded fashion on Unix + Python 3.7 was to use the async_api for reasons I won't get into here).

Chances are you won't need that flexibility though, so I'd just suggest using whatever you're comfortable with.

You should follow the Page Object Model Architecture: https://playwright.dev/python/docs/pom

Example of project

conftest.py
pom/
--login/
----login_page.py --> In this file we will have all selectors for login page and the basic functions for each element, like fill_user, fill_password, click_login_button etc.
--search/
----search_page.py --> In this file we will have all selectors for search page and the basic functions for each element, like fill_search_bar, click_search_button etc.
tests/
--login/
----test_login.py --> In this file we will use the methods that login_page.py contains like (fill_user, fill_password, click_login_button)
--search/
---- test_search.py --> In this file we will use the methods that login_page.py contains and methods that search_page.py contains (fill_search_bar, click_search_button)

For future visitors, the playwright needs access to your /usr/bin and my initial approach of adding different bin directories was wrong. I should have used the following code to extend the PATH: Environment="PATH=$PATH:/usr/bin"

my server is working fine now.
