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](https://www.browserstack.com/accounts/settings) and stop.

> **The BrowserStack MCP server is not auto-registered (issue #978).** > `pw-browserstack` was removed from the plugin's `.mcp.json` because it failed to > connect for every user (the plugin ships no `node_modules`). The `browserstack_*` > MCP tools used below, and the `/pw:browserstack` command, will fail with "tool > not found" until it is enabled manually — see the **Integrations** section of the > plugin's `CLAUDE.md` (`cd integrations/browserstack-mcp && npm install`, then > register the server in your own user/project MCP config). Setting the env vars > alone is not sufficient.

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

MCP Tools Used

| Tool | When | |---|---| | `browserstack_get_plan` | Check account limits | | `browserstack_get_browsers` | List available browsers | | `browserstack_get_builds` | List recent builds | | `browserstack_get_sessions` | Get sessions in a build | | `browserstack_get_session` | Get session details (video, logs) | | `browserstack_update_session` | Mark pass/fail | | `browserstack_get_logs` | Get text/network logs |

Output

• Cross-browser test results table
• Per-browser pass/fail status
• Links to BrowserStack dashboard for video/screenshots
• Any browser-specific failures highlighted
