--- name: browser-use-e2e-c4c7478fe8c2 description: Generate and run E2E tests using browser-use AI automation. This skill should be used when creating automated browser tests, testing authenticated flows, generating test scripts from natural language, or validating user journeys with AI-powered browser control. Handles credentials securely via .env.test with domain-prefixed variables. --- # browser-use E2E Testing ## Overview Generate and execute end-to-end tests using browser-use, an AI-powered browser automation library. Tests are written in natural language and the AI agent figures out the specific interactions. ## Quick Start ### 1. Setup ```bash # Install browser-use uv add browser-use python-dotenv uvx browser-use install ``` ### 2. Configure Credentials Create `.env.test` with domain-prefixed credentials: ```bash # Format: SERVICENAME_USER, SERVICENAME_PASS, SERVICENAME_DOMAIN (optional) GITHUB_USER=your-username GITHUB_PASS=your-password GMAIL_EMAIL=you@gmail.com GMAIL_PASS=your-app-password # Custom app MYAPP_USER=admin MYAPP_PASS=secret MYAPP_DOMAIN=https://app.example.com ``` ### 3. Credential Loader ```python # tests/e2e/conftest.py import os from dotenv import load_dotenv load_dotenv('.env.test') DOMAIN_MAP = { 'GITHUB': 'https://*.github.com', 'GMAIL': 'https://*.google.com', 'GOOGLE': 'https://*.google.com', } def build_sensitive_data() -> dict: """Build browser-use sensitive_data from .env.test vars.""" credentials = {} for key in os.environ: if key.endswith('_USER') or key.endswith('_EMAIL'): prefix = key.rsplit('_', 1)[0] user_val = os.getenv(key) pass_key = f'{prefix}_PASS' pass_val = os.getenv(pass_key) if not pass_val: continue # Determine domain domain_key = f'{prefix}_DOMAIN' domain = os.getenv(domain_key) or DOMAIN_MAP.get(prefix) if not domain: continue # Build credential entry placeholder_user = f'{prefix.lower()}_user' placeholder_pass = f'{prefix.lower()}_pass' credentials[domain] = { placeholder_user: user_val, placeholder_pass: pass_val, } return credentials ``` ## Test Patterns ### Simple Test ```python from browser_use import Agent, Browser, ChatBrowserUse import asyncio async def test_login(): from conftest import build_sensitive_data agent = Agent( task=''' Go to github.com Log in with github_user and github_pass Verify the dashboard loads successfully ''', llm=ChatBrowserUse(), browser=Browser(headless=True), sensitive_data=build_sensitive_data(), use_vision=False, # Security: no screenshots with creds ) result = await agent.run() assert result.is_successful() asyncio.run(test_login()) ``` ### With Pytest ```python # tests/e2e/test_auth.py import pytest from browser_use import Agent, Browser, ChatBrowserUse @pytest.fixture def sensitive_data(): from conftest import build_sensitive_data return build_sensitive_data() @pytest.fixture async def browser(): b = Browser(headless=True) yield b await b.close() @pytest.mark.asyncio async def test_github_login(browser, sensitive_data): agent = Agent( task='Log into github.com with github_user/github_pass, verify repos page', llm=ChatBrowserUse(), browser=browser, sensitive_data=sensitive_data, use_vision=False, ) result = await agent.run() assert result.is_successful() ``` ### Persistent Profile (2FA Sites) ```python from pathlib import Path async def test_with_2fa_profile(): profile_dir = Path.home() / '.browser-use-profiles' / 'github-2fa' browser = Browser( headless=False, user_data_dir=str(profile_dir), ) agent = Agent( task='Go to github.com/settings/security, verify 2FA is enabled', llm=ChatBrowserUse(), browser=browser, # No credentials needed - profile has active session ) result = await agent.run() assert result.is_successful() ``` ### Setup Profile Script ```bash # Run once interactively to save 2FA session python scripts/setup_profile.py --service github --profile-name github-2fa ``` ```python # scripts/setup_profile.py import argparse import asyncio from pathlib import Path from browser_use import Browser async def setup_profile(service: str, profile_name: str): profile_dir = Path.home() / '.browser-use-profiles' / profile_name profile_dir.mkdir(parents=True, exist_ok=True) urls = { 'github': 'https://github.com/login', 'google': 'https://accounts.google.com', 'gitlab': 'https://gitlab.com/users/sign_in', } browser = Browser(headless=False, user_data_dir=str(profile_dir)) ctx = await browser.new_context() page = await ctx.new_page() await page.goto(urls.get(service, service)) input(f'Complete {service} login (including 2FA), then press Enter...') await browser.close() print(f'Profile saved to {profile_dir}') if __name__ == '__main__': parser = argparse.ArgumentParser() parser.add_argument('--service', required=True) parser.add_argument('--profile-name', required=True) args = parser.parse_args() asyncio.run(setup_profile(args.service, args.profile_name)) ``` ## Running Tests ```bash # Run all E2E tests pytest tests/e2e/ -v # Run specific test pytest tests/e2e/test_auth.py::test_github_login -v # Run with visible browser HEADLESS=false pytest tests/e2e/ -v # Generate HTML report pytest tests/e2e/ --html=report.html ``` ## Domain Restriction ```python # Limit where the agent can navigate (security) browser = Browser( allowed_domains=['github.com', 'app.example.com'] ) ``` ## Tips 1. **Credential placeholders**: Use descriptive names like `github_user` not `x_user` 2. **Disable vision** when handling credentials to prevent screenshot leaks 3. **Use profiles** for 2FA - browser-use can't solve CAPTCHAs 4. **Domain restriction** prevents agent from navigating to unexpected sites 5. **Headless in CI** - set `headless=True` for automated pipelines 6. **Test idempotency** - clean up test data or use unique identifiers ## File Structure ``` project/ ├── .env.test # Credentials (git-ignored) ├── tests/ │ └── e2e/ │ ├── conftest.py # Fixtures, credential loader │ ├── test_auth.py # Authentication tests │ └── test_journeys.py # User journey tests └── scripts/ └── setup_profile.py # Profile setup for 2FA ``` --- Source attribution: David-Li0406 Original project: https://github.com/David-Li0406/meta-skill-evloving/blob/ca3a335628981df10c36e00cb9850df2c247ab9a/skill-flow/data/skills-refined-36k/skillsmp/browser-use-e2e/SKILL.md License: Apache-2.0 License information: https://www.apache.org/licenses/LICENSE-2.0 Original upstream instructions; downloaded from Mega AI Hub. ## Upstream license notice Apache License Version 2.0, January 2004 http://www.apache.org/licenses/ TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 1.
