BrowserStack Integration

:material-code-braces: Engineering - Core :material-identifier: `browserstack` :material-github: Source

Install: claude /plugin install engineering-skills

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
  ],
});

3. 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
