I had a problem running an integration test for a plotly-dash app I created. I am trying to run an integration test with selenium remote using pytest and Dash Testing (https://dash.plotly.com/testing)
I was able to run an implementation test locally using the selenium chrome webdriver.
However, it does not work remotely. I created a selenium grid on Google Cloud Platform and can run a simple integration test to see if Google.com loads. This works fine and the following test passes.
test_google.py
def test_query_window_is_visible(browser):
browser.get('https://google.com')
query_window = browser.find_element_by_name('q')
assert query_window.is_displayed()
I can also run the simple integration test using the selenium standalone service in Gitlab with the template produced by Aleksandr Kotlyar (https://gitlab.com/aleksandr-kotlyar/python-gitlabci-selenium/-/tree/1.0.0).
However, when I switch to test the dash app, my integration test to see if the h1 tag loads passes when run locally passes, but when run on Gitlab or by connecting to a remote selenium grid with --remote-url, I get the following errors:
FAILED test_functional.py::test_one - selenium.common.exceptions.WebDriverException: Message: unknown error: net::ERR_CONNECTION_REFUSED
E selenium.common.exceptions.WebDriverException: Message: unknown error: net::ERR_CONNECTION_REFUSED
E (Session info: chrome=x0.0.xxxx.xx)
Any advice to solve this error and run the test remotely would be helpful.
The code was run as follows:
pytest test_functional.py --log-cli-level DEBUG --webdriver Chrome --remote-url http://*selenium grid endpoint ip address hidden*/wd/hub
test_functional.py:
import pytest
from selenium import webdriver
from selenium.webdriver import Remote
from selenium.webdriver.chrome.options import Options
from dash.testing.application_runners import import_app
def test_one(dash_duo):
app = import_app("app")
dash_duo.start_server(app)
dash_duo.wait_for_text_to_equal(
"h1", "Competitor Analysis", timeout=4)
assert dash_duo.find_element(
"h1").text == "Competitor Analysis"
conftest.py
import pytest
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.remote.webdriver import WebDriver
@pytest.fixture(scope='function')
def browser() -> WebDriver:
driver = webdriver.Remote(
command_executor='http://*selenium grid endpoint ip address hidden*/wd/hub',
options=Options())
return driver
