How to run tests on Selenium UI remote machine using WebdriverIO?

[DKasianova]

In protractor to run tests on Selenium UI remote we can specify a 'seleniumAddress' parameter in config. And it will work.
For example:

exports.config = {
...
  baseUrl: 'http://localhost:4200',
  seleniumAddress: 'http://selenium...',

  multiCapabilities: [
    {
      specs: ['./src/**/*.spec.js'],
      browserName: 'chrome',
      name: 'Chrome',
      enableVNC: true,
      enableVideo: false,
      shardTestFiles: true,
      maxInstances: 3,
    },
  ],
  onPrepare,
  onCleanUp,
};

In WebdriverIO there is 'selenium-standalone' service:

export.config = {
    // ...
    services: [
        ['selenium-standalone', {
            logPath: './temp',
            args: {
                version: "3.141.59",
                seleniumArgs: ['-host', 'selenium...', '-port', '4444']
            },
        }]
    ],

But in this case I got an error Unable to connect to "http://localhost:4444/wd/hub", make sure browser driver is running on that address.

What's the easiest way to run tests on remote Selenium UI using WebdriverIO?

Hey @DKasianova,
if you have the service installed it should work out of the box. Just tried it with a fresh WebdriverIO install:#

$ npm i @wdio/cli
$ npx wdio                                                                                                                                                                                                                   [98/1980]
