Answer 1

The best practice is to use "selenium-standalone" and "wdio-selenium-standalone-service" npm packages, so if you don't have them in devDependencies in your package.json, add them.

Once you have these packages, you need first to download and install selenium drivers with console command: ./node_modules/.bin/selenium-standalone install --config=./config/selenium.config.js, where your selenium.config.js file should look like this .

Once installed, the "wdio-selenium-standalone-service" will automatically start the node server for you each time before tests start (if you use wdio testrunner)

I also face the problem of Error: connect ECONNREFUSED 127.0.0.1:4444. Try many ways like: update Chrome, update ChromeDriver, set environment Path, but still doesn't work. Then, I update my Java runtime, now it can work now.
