@wdio/browserstack-service

What is @wdio/browserstack-service?

@wdio/browserstack-service is a WebdriverIO service that provides integration with BrowserStack, a cloud-based cross-browser testing platform. This service allows you to run your WebdriverIO tests on BrowserStack's infrastructure, enabling you to test your web applications across a wide range of browsers and devices.

What are @wdio/browserstack-service's main functionalities?

BrowserStack Local Testing

This feature allows you to test your local applications on BrowserStack by establishing a secure connection between your local machine and BrowserStack's infrastructure.

const { remote } = require('webdriverio');
const browserstack = require('@wdio/browserstack-service');

const options = {
  user: 'YOUR_BROWSERSTACK_USERNAME',
  key: 'YOUR_BROWSERSTACK_ACCESS_KEY',
  services: ['browserstack'],
  capabilities: {
    'bstack:options': {
      os: 'Windows',
      osVersion: '10',
      local: true,
      seleniumVersion: '3.141.59'
    },
    browserName: 'chrome',
    browserVersion: 'latest'
  }
};

(async () => {
  const browser = await remote(options);
  await browser.url('http://localhost:3000');
  console.log(await browser.getTitle());
  await browser.deleteSession();
})();

Parallel Testing

This feature allows you to run tests in parallel across multiple browsers and operating systems, significantly reducing the time required for test execution.

const { remote } = require('webdriverio');
const browserstack = require('@wdio/browserstack-service');

const options = {
  user: 'YOUR_BROWSERSTACK_USERNAME',
  key: 'YOUR_BROWSERSTACK_ACCESS_KEY',
  services: ['browserstack'],
  capabilities: [
    {
      'bstack:options': {
        os: 'Windows',
        osVersion: '10',
        seleniumVersion: '3.141.59'
      },
      browserName: 'chrome',
      browserVersion: 'latest'
    },
    {
      'bstack:options': {
        os: 'OS X',
        osVersion: 'Big Sur',
        seleniumVersion: '3.141.59'
      },
      browserName: 'safari',
      browserVersion: 'latest'
    }
  ]
};

(async () => {
  const browser1 = await remote(options.capabilities[0]);
  const browser2 = await remote(options.capabilities[1]);
  await browser1.url('https://www.example.com');
  await browser2.url('https://www.example.com');
  console.log(await browser1.getTitle());
  console.log(await browser2.getTitle());
  await browser1.deleteSession();
  await browser2.deleteSession();
})();

Automated Screenshots

This feature allows you to take automated screenshots of your web application during test execution, which can be useful for visual regression testing and debugging.

const { remote } = require('webdriverio');
const browserstack = require('@wdio/browserstack-service');

const options = {
  user: 'YOUR_BROWSERSTACK_USERNAME',
  key: 'YOUR_BROWSERSTACK_ACCESS_KEY',
  services: ['browserstack'],
  capabilities: {
    'bstack:options': {
      os: 'Windows',
      osVersion: '10',
      seleniumVersion: '3.141.59'
    },
    browserName: 'chrome',
    browserVersion: 'latest'
  }
};

(async () => {
  const browser = await remote(options);
  await browser.url('https://www.example.com');
  await browser.saveScreenshot('./screenshot.png');
  await browser.deleteSession();
})();

Instructions on how to install WebdriverIO can be found here.

Configuration

WebdriverIO has Browserstack support out of the box. You should simply set user and key in your wdio.conf.js file. This service plugin provides supports for Browserstack Tunnel. Set browserstackLocal: true also to activate this feature. Reporting of session status on BrowserStack will respect strict setting of Cucumber options.

// wdio.conf.js
export.config = {
    // ...
    user: process.env.BROWSERSTACK_USERNAME,
    key: process.env.BROWSERSTACK_ACCESS_KEY,
    services: [
        ['browserstack', {
            browserstackLocal: true
        }]
    ],
    // ...
};

Options

In order to authorize to the BrowserStack service your config needs to contain a user and key option.

browserstackLocal

Set this to true to enable routing connections from Browserstack cloud through your computer. You will also need to set browserstack.local to true in browser capabilities.

Type: Boolean
Default: false

preferScenarioName

Cucumber only. Set this to true to enable updating the session name to the Scenario name if only a single Scenario was ran. Useful when running in parallel with wdio-cucumber-parallel-execution.

Type: Boolean
Default: false

forcedStop

Set this to true to kill the browserstack process on complete, without waiting for the browserstack stop callback to be called. This is experimental and should not be used by all. Mostly necessary as a workaraound for this issue.

Type: Boolean
Default: false

opts

Specified optional will be passed down to BrowserstackLocal. See this list for details.

Type: Object
Default: {}

Known Issues

• It's more of how webdriverio desigend the multi-process model. It is extremely hard if not impossible to reliable transfer localIdentifier to child-processes. We recommend to use it without the identifier at this moment, which will create an account-wide local tunnel.
