Problem running docker-chromium-xvfb about docker-chromium-xvfb

[mark-adams]

That seems strange. Can you include your Dockerfile, your test script, and the docker command that you're using to execute it so that I can help more?

I had a same problem, I had solved with follows script in Dockerfile:
export DISPLAY=:1
Xvfb $DISPLAY -ac -screen 0 1280x1024x8 &
sleep 1

the stackoverflow url:

I tested this with the latest images on my sample applications (samples/python2, samples/python3) and everything appears to be working fine.

@rogthedodge, without a copy of your Dockerfile and script, I'm not sure there's much more to do on this one. Please reopen if you still are experiencing the issue.

Hii adams,

• When I ran selenium test case using docker i got this error:

======================================================================

• This is my docker file code:

• This is my test case:

import unittest
from selenium import webdriver
from selenium.webdriver.common.keys import Keys

class ExampleTests(unittest.TestCase):

    def setUp(self):
        self.driver = webdriver.Chrome('/usr/local/bin/chromedriver')

    def test_google_title_matches_correct_value(self):
        self.driver.get("http://www.google.com")
        input_box = self.driver.find_element_by_id('lst-ib')
        input_box.send_keys('apple', Keys.RETURN)
        assert "Google" in self.driver.title
        self.driver.save_screenshot('google.png')

    def tearDown(self):
        self.driver.close()
                                                                     

• How can we resolve the above issue? And how can we use chrome driver version (2.29).
