Usage:

For the following alpine based images:

  • latest
  • 3.7-alpine3.8
  • 3.7-alpine3.8-selenium
  • 3.6-alpine3.7
  • 3.6-alpine3.7-selenium
  • 2.7-alpine3.7
  • 2.7-alpine3.7-selenium

Run the followings in your terminal:

$ cd [your working directory]
$ docker run -it -v $(pwd):/usr/workspace joyzoursky/python-chromedriver:[version] sh
/ # cd /usr/workspace

For the following ubuntu based images:

  • 3.7
  • 3.7-selenium
  • 3.6
  • 3.6-selenium
  • 3.6-xvfb
  • 3.6-xvfb-selenium
  • 2.7
  • 2.7-selenium
  • 2.7-xvfb
  • 2.7-xvfb-selenium

Run the followings in your terminal:

$ cd [your working directory]
$ docker run -it -v $(pwd):/usr/workspace joyzoursky/python-chromedriver:[version] bash
root@[container ID]:/# cd /usr/workspace

This will create a container from the image. Then you could starting running the commands in the container as in your working directory. The followings are some examples to run a selenium test.

Examples to run selenium test in the container:

You can download a selenium test example from here to quick start.

For the following images with selenium pre-installed:

  • 3.7-alpine3.8-selenium
  • 3.7-selenium
  • 3.6-alpine3.7-selenium
  • 3.6-selenium
  • 2.7-alpine3.7-selenium
  • 2.7-selenium

You may run:

# python test_script.py

For the following images that do not have selenium pre-installed:

  • latest
  • 3.7-alpine3.8
  • 3.7
  • 3.6-alpine3.7
  • 3.6
  • 2.7-alpine3.7
  • 2.7

You may run:

# pip install selenium==3.13.0
# python test_script.py

If you see the runtime error ConnectionResetError: [Errno 104] Connection reset by peer, revert your selenium version to 3.8.0.

For 3.6-xvfb or 2.7-xvfb, you may run:

# pip install selenium==3.8.0
# xvfb-run --server-args="-screen 0 1024x768x24" python test_script.py

For 3.6-xvfb-selenium or 2.7-xvfb-selenium, you may run:

# xvfb-run --server-args="-screen 0 1024x768x24" python test_script.py

Then you should see the test result like this:

test_case_1 (__main__.TestTemplate)
Find and click top-right button ... ok
test_case_2 (__main__.TestTemplate)
Find and click Learn more button ... ok
