Using CodeceptJS and Browserstack with localIdentifier does not work correctly.

[satoshi-kawasaki]

What are you trying to achieve?

Hello,

I'm trying to run E2E tests using a combination of CodeceptJS + WebDriverIO and Browserstack.

Since the test needs to be run locally on a separate connection from the CI/CD Pipeline, the localIdentifier value is specified as follows:

codecept.config.js

desiredCapabilities: {
  project: "target",
  "browserstack.local": "true",
  "browserstack.debug": "true",
  "browserstack.networkLogs": "true",
  "browserstack.console": "errors",
  "browserstack.user": "dummyuser",
  "browserstack.key": "dummykey",
  "browserstack.networkLogs": "true",
  "browserstack.localIdentifier": uuidv4(),
},

startBrowserStackLocal.js

const bs_local = new browserstack.Local();
const bs_local_args = {
  key: "dummykey",
  forceLocal: true,
  localIdentifier:
    config.helpers.WebDriver.desiredCapabilities[
      "browserstack.localIdentifier"
    ],
};

bs_local.start(bs_local_args, function () {
  console.log(">>>> BrowserStack-local START.");
});

However, when you run the E2E test, you get the following error:

Please make sure Selenium Server is running and accessible

[browserstack.local] is set to true but local testing through BrowserStack is not connected.

I am getting an error trying to access the value of a property that does not exist in the config file. Is this a bug?

Or something changed 🤔

@PeterNgTr Thank you for your reply to e's Browser.

I corrected it referring to the URL of the link you told me, but it doesn't work.

If I use a Browserstack Selenium server for E2E testing, do I need to set onlyAutomate in config?
