Chrome Alpine (Chromium)

[aleksandr-kotlyar]

Problem

If use current version webdriver_manager 2.3.0 with Apline linux distributions - it can't find chrome browser in path, because there is no google-chrome distib at alpine repository.

Here is the code:

import logging
from webdriver_manager import utils
def test_chrome_version():
    logging.info(utils.chrome_version())

Here is the stacktrace:

_____________________________ test_chrome_version ______________________________
src/test/test_wdm.py:16: in test_chrome_version
    logging.info(utils.chrome_version())
/usr/local/lib/python3.7/site-packages/webdriver_manager/utils.py:98: in chrome_version
    .format(cmd)
E   ValueError: Could not get version for Chrome with this command: google-chrome --version

Here is Dockerfile python:3.7-alpine + chrome:3.11-alpine

Solution

I think we need to add checker if linux uses chromium or google-chrome browser.
I suggest two vartiants:

First

That we can add check if OS.ID is Alpine, we can try to extract id of distribution like here, but python-like:

$ cat /etc/os-release
NAME="Alpine Linux"
ID=alpine
VERSION_ID=3.11.3
PRETTY_NAME="Alpine Linux v3.11"
HOME_URL="https://alpinelinux.org/"
BUG_REPORT_URL="https://bugs.alpinelinux.org/"
$ source /etc/os-release && echo "$ID"
alpine

Second

Add second try to execute cmd='chromium --version' if os_name() == OSType.LINUX:

# webdriver_manager/utils.py
def chrome_version():
    pattern = r'\d+\.\d+\.\d+'
    cmd_mapping = {
        OSType.LINUX: 'google-chrome --version',
        OSType.MAC: r'/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --version',
        OSType.WIN: r'reg query "HKEY_CURRENT_USER\Software\Google\Chrome\BLBeacon" /v version'
    }

    cmd = cmd_mapping[os_name()]
    stdout = os.popen(cmd).read()
    version = re.search(pattern, stdout)
    if not version:
        if os_name() == OSType.LINUX:
            cmd = 'chromium-browser --version'
            try:
                stdout = os.popen(cmd).read()
                version = re.search(pattern, stdout)
                assert version
                return version.group(0)
            except AssertionError:
                raise ValueError('Could not get version for Chrome with this command: {}'.format(cmd))
        raise ValueError('Could not get version for Chrome with this command: {}'.format(cmd))
    return version.group(0)

I can make a PR, but want to discuss first, which solution is better.
@SergeyPirogov what do you think, which solution is better? Or maybe we should wait if someone can suggest the best one?
