Question

How to make geckdriver not stop the Marionette listener when the session is closed?

284 Views Asked by Douglas Cardoso At 12 June 2023 at 01:42

thanks in advance for take a time to help me. I'm working on a Python library that runs asynchronous REST requests to WebDrivers and one issue I have is that when I close the GeckoDriver (Firefox) session, following the W3 Webdriver documentation, the WebDriver stops listening Marionette, freezes for a while and starts listening Marionette on a new port. I've been using GeckoDriver and ChromeDriver both in version 113 to test the library, and for ChromeDriver it does not happens. The tests run smoothly and fast.

Here is what I do to reproduce the issue:

I open one terminal (I'm using Ubuntu 20.04) and start GeckoDriver on port 9999 ./geckodriver --port=9999
In a new terminal I execute one of my test cases with python -m pytest that opens a session in WebDriver, do some stuff and closes it. Here is the code.

from pytest import fixture, mark
from caqui import asynchronous, synchronous  # this is from my library. Install with 'pip install caqui'
from tests.constants import PAGE_URL  # it is a local html, like '/html/playground.html'

@fixture
def __setup():
    driver_url = "http://127.0.0.1:9999"  # this is the URL to Geckodriver I started previously
    capabilities = {
        "desiredCapabilities": {
            "name": "webdriver",
            "browserName": "firefox",
            "marionette": True,
            "acceptInsecureCerts": True,
        }
    }
    session = synchronous.get_session(driver_url, capabilities)
    synchronous.go_to_page(
        driver_url,
        session,
        PAGE_URL,
    )
    yield driver_url, session
    synchronous.close_session(driver_url, session)

@mark.asyncio
async def test_click(__setup):
    driver_url, session = __setup
    locator_type = "xpath"
    locator_value = "//button"

    element = synchronous.find_element(driver_url, session, locator_type, locator_value)

    assert await asynchronous.click(driver_url, session, element) is True

When I go to the terminal where GeckoDriver is running, I can see this error. I tried to search for a solution, but I couldn't find anything that helps me. I appreciate any tip to fix it.
