Not able to configure multiple browser's os, os.version and browser version for Browserstack execution

What are you trying to achieve?

I want to run tests in browser stack on multiple browsers. When I say multiple browsers, I need privilege to configure its os, os.version and browser.version thru desiredCapabilities. I tried various possibilities but its not working.

What do you get instead?

A. Below errors. I know what it means but just to make sure I made the config file as advised from slack support.

paste output here

RangeError: Maximum call stack size exceeded

**Run Command**: codeceptjs run-multiple basic

1st Problem is in wrong parameters in config. Browserstack supports os and os_version instead of browserstack.os and browserstack.os_version.

2nd problem is about maximum callstack. Don’t use browser in desiredCapabilities. Array for multiple coniguration should consist of browser names (like chrome) or WebDriverIO configuration objects (object with ‘browser’ and ‘desiredCapabilities’ - https://codecept.io/helpers/WebDriverIO/#configuration)

Your should look’s like this:

{
  "tests": "./end2end/tests/web/collectionOrder_01_test.js",
  "output": "./output",
  "multiple": {
    "basic": {
      "browsers": [
        "chrome",
        {
          "browser": "safari",
          "desiredCapabilities": {
            "os": "OS X",
            "os_version": "High Sierra",
            "resolution": "maximize"
          }
        },
        {
          "browser": "chrome",
          "desiredCapabilities": {
            "os": "OS X",
            "os_version": "High Sierra",
            "resolution": "maximize"
          }
        }
      ]
    }
  },
  "helpers": {
    "WebDriverIO": {
      "url": "https://hidden.com/",
      "browser": "Chrome",
      "user": "hidden",
      "key": "hidden",
      "desiredCapabilities": {
        "browserstack.local": false,
        "browserstack.video": true,
        "ignoreHTTPSErrors": true,
        "acceptInsecureCerts": true,
        "acceptInvalidCerts": true,
        "acceptSslCerts": true
      }
    },
    "WebDriverIOHelper": {
      "require": "./end2end/utility/webdriverio_helper.js"
    }
  },

  "include": {
    "homePage": "./end2end/pageObjects/homePage"
  },
  "bootstrap": false,
  "mocha": {},
  "name": "codecept",
  "plugins": {
    "allure": {
      "enabled": true
    }
  }
}

For correct parameters use BrowserStack configuration tool https://www.browserstack.com/automate/capabilities
