Hii Adams,

• We used your image(python2) to run the selenium test cases.
• image
• In single file, we wrote two test cases 1: One with send keys, 2: Another one without sending keys.
• The test case without using send keys is passed and another one with sending keys is failed.
• Test_case file link
• This is the final output

test_google_with_send_keys (testing.ExampleTests) ... ERROR
test_google_without_send_keys (testing.ExampleTests) ... ok

I got it working by replacing the line chromium --no-sandbox $@ & with chromium --no-sandbox --headless $@ & in the file https://github.com/mark-adams/docker-chromium-xvfb/blob/master/images/base/xvfb-chromium

Hope that helps!
