Update how repo downloads Chromedriver

[dequejenn]

Epic https://github.com/dequelabs/axe-api-team/issues/497

Proposal: https://github.com/dequelabs/axe-api-team/blob/ac01e14fc119965e2ccb4bd834a5554cedb275dd/proposals/technical-requirements/chrome-driver-download-steps-in-central-place.md

Upgrade version of browser-driver-manager in each repository CI configuration

browser-driver-manager should upgrade its version so that the repos can use the new chrome driver installation method.

Update repos that downloads chromedriver

Each repo that downloads chromedriver will need to do it using browser-driver-manager

Please reference Usage guide

Usage

When using this chromedriver path in the tests, you can use the following code to get the path of the chromedriver:

Getting the path of chromedriver

To be able to get the path of where chromedriver exist in non-node libraries each library can read the .env file created by browser-driver-manager and get the path from there.

NPM based packages

const { config } = require('dotenv')
const os = require('os')
const path = require('path')

const HOME_DIR = os.homedir()
const BDM_CACHE_DIR = path.resolve(HOME_DIR, '.browser-driver-manager')

config({ path: path.resolve(BDM_CACHE_DIR, '.env') })

const { CHROMEDRIVER_TEST_PATH, CHROME_TEST_PATH } = process.env

Non-NPM based packages (Psuedo code)

from os import path
from dotenv import dotenv_values

env = dotenv_values(path.join(path.expanduser('~'), '.browser-driver-manager', '.env'))
chromedriver_path = env['CHROMEDRIVER_TEST_PATH']
chrome_path = env['CHROME_TEST_PATH']

require 'dotenv'

Dotenv.load(File.join(Dir.home, '.browser-driver-manager', '.env'))
chromedriver_path = ENV['CHROMEDRIVER_TEST_PATH']
chrome_path = ENV['CHROME_TEST_PATH']
