[BUG] dash_duo does not set remote thus fails when get_webdriver is called #829

Closed Oronis closed 5 years ago

Oronis commented 5 years ago

Describe your context

dash                                           1.0.2
dash-core-components                           1.0.0
dash-html-components                           1.0.0
dash-renderer                                  1.0.0
dash-table                                     4.0.2

Describe the bug

Trying to use new dash.testing. Running the example code copied from the documentation (https://dash.plot.ly/testing) in a headless mode (with a Chrome webdriver running).

An error gets thrown in 

dash\testing\browser.py:47: in __init__
    self._driver = until(lambda: self.get_webdriver(remote), timeout=1)

It appears that the variable remote is never set in the call stack of dash_duo and thus the call to get_webdriver always fails.

Expected behavior

It should work. I don't know what else to say beyond the basic example doesn't appear to work. If there is some setup requirement that is missing, then a clarification on the documentation needs to be added, otherwise at some point in the setup of dash_duo the value of remote needs to be set such that the get_webdriver call doesn't fail and it correctly fetches the webdriver when initialising the browser.

@Oronis thank you for reporting the dash.testing issue in details. It looks like an extra option --disable-gpu is needed on Windows OS.

can you give it a quick try before I can find a windows machine for verification?

  1. upgrade to latest chrome and webdriver

  2. configure the option as follow if #1 doesn't work

define this in your top conftest.py

from selenium.webdriver.chrome.options import Options

def pytest_setup_options():
    """called before webdriver is initialized"""
    options = Options()
    options.add_argument('--disable-gpu')
    return options

I will also update the document once the fix is confirmed.

@byronz I'm afraid I'm on a managed PC and haven't been able to force an update to version 76. I've done everything else and I'm afraid this doesn't seem to affect the issue. It still fails when calling get_webdriver as the value of remote is never set in the code.

As a quick check, how or when is this value supposed to be set? I've tried to sense check the code and, as far as I can see from debugging it, the value is always None when called from the dash_duo initialisation and thus will always cause the call to until to fail.

@Oronis the remote is like a reserved parameter in case we might need selenium grid, it's normal that it's always None in our current usage. it calls (in this case) the private getattr(self, "_get_{}".format(self._browser))() to initialize the corresponding browser per browser name. so the actual call for Chrome case is _get_chrome. 

    def get_webdriver(self, remote):
        try:
            return (
                getattr(self, "_get_{}".format(self._browser))()
                if remote is None
                else webdriver.Remote(
                    command_executor=remote,
                    desired_capabilities=getattr(
                        DesiredCapabilities, self._browser.upper()
                    ),
                )
            )
        except WebDriverException:
            logger.exception("<<<Webdriver not initialized correctly>>>")
            return None

@Oronis
can you paste the structure of your folder? the location of the conftest and tests can you increase the log level by pytest --headless --log-cli-level DEBUG and past the log here?

thanks

Thanks, I'm afraid I'm very ill at the moment so not able to follow up right now. I'll take a look as soon as I can and update this report.

no worries, get well soon.

I've run into what appears to be the same issue -- not on windows, but trying to setup a CI build using gitlab-ci / docker. The same sequence of build steps runs fine on my own linux installation and on another test machine running OSX. I've tried using a variety of base docker images (python:3.7, some variants with chromedriver installed), all to no effect.

See below -- may be helpful in replicating the issue without a windows box? Two variants included. The simplest installs chromium and chromedriver. The second (commented out) uses pytest-selenium and a separate selenium/chromedriver docker image as a service. Both exhibit the same issue described by @Oronis 

# Official framework image. Look for the different tagged releases at:
