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: 1. Check current playwright.config.ts 2. 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
  ],
});

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

2. Run Tests on BrowserStack

/pw:browserstack run

Steps: 1. Verify credentials are set 2. Run tests with BrowserStack projects:

BROWSERSTACK_USERNAME=$BROWSERSTACK_USERNAME \
BROWSERSTACK_ACCESS_KEY=$BROWSERSTACK_ACCESS_KEY \
npx playwright test --project='chrome@*' --project='firefox@*'

3. Monitor execution 4. Report results per browser

3. Get Build Results

/pw:browserstack results

Steps: 1. Call browserstack_get_builds MCP tool 2. Get latest build's sessions 3. For each session: - Status (pass/fail) - Browser and OS - Duration - Video URL - Log URLs 4. Format as summary table

4. Check Available Browsers

/pw:browserstack browsers

Steps: 1. Call browserstack_get_browsers MCP tool 2. Filter for Playwright-compatible browsers 3. Display available browser/OS combinations

5. Local Testing

/pw:browserstack local

For testing localhost or staging behind firewall: 1. Install BrowserStack Local: npm install -D browserstack-local 2. Add local tunnel to config 3. Provide setup instructions
