WebDriverIO Selenium pass command line arguments into Chrome from config.js file

You can set any chrome flags within the desired capabilities using goog:chromeOptions

capabilities: [{
    browserName: 'chrome',
    'goog:chromeOptions': {
        args: ['disable-web-security']
    }
}]

Check out the chromedriver docs for more information on the chromeOptions object.

This ended up being the correct syntax, thanks Christian!

  capabilities: [{
        browserName: 'chrome',
         'goog:chromeOptions': {
            args: ['--disable-web-security']
        }
    }]

Something has been changed because in @wdio/cli version 5.11.13 and chromedriver version 76.0.0 I cannot pass parameter chromeOptions - result: invalid argument: unrecognized capability: chromeOptions.

I did some research and passing goog:chromeOptions works:

  capabilities: [{
    browserName: 'chrome',
    'goog:chromeOptions': {
      args: ['--disable-web-security'],
    },
  }]
