BrowserStack Integration

Run Playwright tests on BrowserStack's cloud grid for cross-browser and cross-device testing.

Prerequisites

Environment variables must be set:

• BROWSERSTACK_USERNAME — your BrowserStack username

• BROWSERSTACK_ACCESS_KEY — your access key

If not set, inform the user how to get them from browserstack.com/accounts/settings and stop.

Capabilities

1. Configure for BrowserStack

/pw:browserstack setup

Steps:

• Check current playwright.config.ts

• Add BrowserStack connect options:

// Add to playwright.config.ts

import { defineConfig } from '@playwright/test';

const isBS = !!process.env.BROWSERSTACK_USERNAME;

export default defineConfig({

  // ... existing config

  projects: isBS ? [

    {

      name: "chromelatestwindows-11",

      use: {

        connectOptions: {

          wsEndpoint: `wss://cdp.browserstack.com/playwright?caps=${encodeURIComponent(JSON.stringify({

            'browser': 'chrome',

            'browser_version': 'latest',

            'os': 'Windows',

            'os_version': '11',

            'browserstack.username': process.env.BROWSERSTACK_USERNAME,

            'browserstack.accessKey': process.env.BROWSERSTACK_ACCESS_KEY,

          }))}`,

        },

      },

    },

    {

      name: "firefoxlatestwindows-11",

      use: {

        connectOptions: {

          wsEndpoint: `wss://cdp.browserstack.com/playwright?caps=${encodeURIComponent(JSON.stringify({

            'browser': 'playwright-firefox',

            'browser_version': 'latest',

            'os': 'Windows',

            'os_version': '11',

            'browserstack.username': process.env.BROWSERSTACK_USERNAME,

            'browserstack.accessKey': process.env.BROWSERSTACK_ACCESS_KEY,

          }))}`,

        },

      },

    },

    {

      name: "webkitlatestos-x-ventura",

      use: {

        connectOptions: {

          wsEndpoint: `wss://cdp.browserstack.com/playwright?caps=${encodeURIComponent(JSON.stringify({

            'browser': 'playwright-webkit',

            'browser_version': 'latest',

            'os': 'OS X',

            'os_version': 'Ventura',

            'browserstack.username': process.env.BROWSERSTACK_USERNAME,

            'browserstack.accessKey': process.env.BROWSERSTACK_ACCESS_KEY,

          }))}`,

        },

      },

    },

  ] : [

    // ... local projects fallback

  ],

});

• Add npm script: "test:e2e:cloud": "npx playwright test --project='chrome@*' --project='firefox@*' --project='webkit@*'"

2. Run Tests on BrowserStack

/pw:browserstack run

Steps:

• Verify credentials are set

• Run tests with BrowserStack projects:

BROWSERSTACK_USERNAME=$BROWSERSTACK_USERNAME \

BROWSERSTACK_ACCESS_KEY=$BROWSERSTACK_ACCESS_KEY \

npx playwright test --project='chrome@*' --project='firefox@*'

• Monitor execution

• Report results per browser

3. Get Build Results

/pw:browserstack results

Steps:

• Call browserstack_get_builds MCP tool

• Get latest build's sessions

• For each session:

• Status (pass/fail)

• Browser and OS

• Duration

• Video URL

• Log URLs

• Format as summary table

4. Check Available Browsers

/pw:browserstack browsers

Steps:
