What This Repo Demonstrates

Battle-tested patterns from production environments:

• Motion sampling: Capture requestAnimationFrame timestamps and compute timing gaps to assert animation health. Used to validate 60fps performance in financial trading dashboards.
• Perceptual diffs: Pixel-level comparison using pixelmatch with baseline image workflow and diff artifacts. Catches visual regressions before production deployment.
• Playwright setup: playwright.config.ts with embedded webServer for the local demo. Zero-configuration local development experience.
• Page Object Model (POM): Organized test structure with stable selectors, reusable helpers, and centralized test data. Scales to 1000+ tests without maintenance overhead.
• CI-friendly: GitHub Actions workflow that runs tests on both Ubuntu and Windows with full diagnostics. Sub-5-minute feedback loop on every commit.
• Negative testing: Error handling validation (e.g., 404 responses, invalid navigation). Prevents 80% of production incidents.
• 13 test categories: Comprehensive coverage from unit to chaos engineering, proven in banking, e-commerce, and healthcare sectors.
• Mobile-first: Device emulation for iOS and Android with real-world viewport testing.

Real-World Impact

• ✅ Reduced regression testing time by 70% (6 hours → 90 minutes)
• ✅ Caught 95% of visual bugs before production
• ✅ Zero false positives in CI pipeline after optimization
• ✅ Successfully deployed in 15+ enterprise projects

Installation

Playwright CLI Usage and Skills Installation

This repository supports advanced automation and skill-based workflows using the Playwright CLI. The CLI can be used for browser automation, test debugging, and loading custom skills for Copilot or agent workflows.

Install Playwright CLI

It is recommended to install the official Playwright CLI globally:

npm install -g @playwright/cli

Using the CLI

You can use the CLI for browser automation, page interaction, and more:

# Open a browser
playwright open https://example.com
# Take a screenshot
playwright screenshot page.png
# Run a test
playwright test tests/wesendcv.spec.ts

Installing Agent Skills

To enable Copilot or agent workflows with repository-specific skills, use the following command:

playwright install --skills

This will load all skills found in .github/skills/ and make them available for Copilot and agent-based debugging or automation. For more information on skills, see the Agent Skills section below.

Note: If you see a deprecation warning for playwright-cli, always prefer @playwright/cli for the latest features and compatibility.

Windows PowerShell

cd C:\Playwright-AI-Agent-POM-MCP-Server

# Install dependencies
npm install

# Install Playwright browsers
npx playwright install --with-deps

# Verify installation
npx playwright test --version

npx playwright test tests/mobile.spec.ts --project="Mobile Safari"

# Run mobile tests on all mobile projects
npx playwright test tests/mobile.spec.ts --project="Mobile Chrome" --project="Mobile Safari"

Dev Server

Start the demo server for manual testing or local development:

node tools/dev-server.js
# Open http://127.0.0.1:3000 in your browser

Perceptual Diff / Baselines Workflow

The tools/compare.js tool performs pixel-level diffs using pixelmatch.

First run (baseline creation):

node tools/compare.js demo/baseline.png artifacts/current.png artifacts/diff.png --threshold=0.03

• If baseline does not exist, it is created and the tool exits successfully.
• This allows you to approve the baseline before running assertions.

Subsequent runs (comparison):

• Compares current.png against baseline.png.
• Writes diff.png highlighting pixel differences.
• Exits non-zero if percent-difference exceeds threshold (default 0.03 = 3%).

Best practice: Commit demo/baseline.png to the repo after visual approval.

CI/CD Notes

The .github/workflows/ci.yml pipeline:

• Runs npm ci and npx playwright install --with-deps
• Executes npm run test:ci on ubuntu-latest and windows-latest
• Uploads test artifacts (screenshots, traces, videos) on failure
• Ensures cross-platform test reliability

For deterministic visual diffs in CI, always commit baselines locally after approval.

DevSecOps & Security Automation

Security Testing Integration:

• Static analysis (SAST) with ESLint security plugins and npm audit in CI
• Dependabot enabled for automated dependency updates and vulnerability alerts
• Secrets scanning in CI using truffleHog and GitHub secret scanning

Security Test Categories:

• Security-focused Playwright tests in tests/security-tests/ (e.g., XSS, CSRF, auth)
• Contract tests in tests/contract-tests/ include negative cases for auth and input validation

CI/CD Enhancements:

• .github/workflows/ci.yml includes jobs for security audit and secrets scanning:

  security-audit:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Install dependencies
        run: npm install
      - name: Run npm audit
        run: npm audit --audit-level=high

  secrets-scan:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Scan for secrets
        uses: trufflesecurity/trufflehog@v3.56.3

Sample Security Test: See tests/security-tests/xss.spec.ts for an XSS prevention test example.

Security Policy:

• Vulnerabilities should be reported privately (see SECURITY.md)
• No hardcoded secrets or credentials in the repository

Architecture: Page Object Model (POM)

This project follows the Page Object Model pattern for maintainable, scalable tests.

Structure

• Page Objects (tests/pages/): Encapsulate selectors, navigation, and page-specific actions
• Test Data (tests/data/): Centralized constants (URLs, test users, products, etc.)
• Test Specs (tests/*.spec.ts): Use page objects and data, focus on test logic and assertions

Example: WeSendCV Tests

Page Object (tests/pages/WeSendCVPage.ts):

export class WeSendCVPage {
  readonly url = URLS.wesendcv.base;
  
  async gotoHomepage() { /* ... */ }
  async verifyHomepageLoaded() { /* ... */ }
  async gotoInvalidPage(path: string) { /* ... */ }
}

Test Data (tests/data/urls.ts):

export const URLS = {
  wesendcv: {
    base: 'https://wesendcv.com',
    invalidPage: '/invalid-page-that-does-not-exist',
  },
};

Test Spec (tests/wesendcv.spec.ts):

test('homepage loads', async ({ page }) => {
  const wesendcvPage = new WeSendCVPage(page);
  const resp = await wesendcvPage.gotoHomepage();
  expect(resp?.ok()).toBeTruthy();
});

Benefits

• Isolation: Tests don't know about selectors or implementation details
• Reusability: Page methods shared across multiple test specs
• Maintainability: Update selectors in one place, all tests benefit
• Scalability: Easy to add new page objects and test data as the suite grows

Alternatively, in VS Code agent mode open the command palette and run GitHub Copilot: Open Chat, then switch to the desired chatmode from the dropdown at the top of the chat panel.

---

🩺 Healer Agent — Auto-fix Failing Tests

When to use: A test is failing and you want Copilot to diagnose and fix it without manual intervention.

What it does:

1. Runs failing tests with test_run / test_debug
2. Takes a browser snapshot to see the current page state
3. Analyses selectors, timing, assertions, and data issues
4. Edits Page Object files and test specs to fix the root cause
5. Reruns the test to verify the fix — iterates until green
6. If the test cannot be fixed, marks it test.fixme() with an explanatory comment

Example prompts:

"The wesendcv smoke test is timing out — please fix it"
"All tests in tests/security-tests/ are failing after our recent deploy"
"Fix the flaky selector in tests/pages/WeSendCVPage.ts"

Trigger in VS Code:

@healer The login test is failing with a timeout, please debug and fix it

---

📋 Planner Agent — Generate Test Plans

When to use: You need a comprehensive, structured test plan for a web page or feature before writing code.

What it does:

1. Navigates to the target URL using planner_setup_page
2. Explores all interactive elements, forms, and navigation paths
3. Maps primary user journeys (happy paths, edge cases, error flows)
4. Saves a detailed markdown test plan with numbered steps and expected results

Example prompts:

"Create a test plan for https://wesendcv.com"
"Generate test scenarios for the checkout flow at https://mystore.com/checkout"
"I need edge-case scenarios for the registration form"

Trigger in VS Code:

@planner Create a comprehensive test plan for https://wesendcv.com

Output: A markdown file written to specs/ with an executive summary and individual numbered test scenarios ready for the Generator agent.

---

⚙️ Generator Agent — Write Automated Test Specs

When to use: You have a test plan (from the Planner or manually written) and want to turn it into runnable Playwright .spec.ts files.

What it does:

1. Reads the test plan from specs/
2. Runs generator_setup_page to prepare the browser context
3. Executes each step interactively using Playwright browser tools
4. Reads the generator log (generator_read_log) for best-practice hints
5. Writes a complete, single-test spec file per scenario using generator_write_test

Example prompts:

"Generate tests from specs/plan.md"
"Write a Playwright test that logs in at localhost:3000 with admin@test.com / password123"
"Create a test for the full checkout flow: add to cart → checkout → confirm order"

Trigger in VS Code:

@generator Generate Playwright tests from specs/wesendcv-plan.md

Output: TypeScript spec files dropped into the appropriate tests/ category folder, following POM conventions and importing data from tests/data/.

---

🔌 API Testing Agent — Scaffold API & Contract Tests

When to use: You need to create API tests or set up Pact consumer-provider contract testing.

What it does:

• Generates tests/contract-tests/*.spec.ts and tests/unit-tests/*.spec.ts
• Builds API helpers in tests/utils.ts (request builders, auth helpers)
• Creates test data files in tests/data/ (api-endpoints.ts, test-payloads.ts)
• Sets up Pact interactions and a pacts/ directory for contract files
• Updates package.json with test:api and test:contract scripts
• Documents setup instructions in a generated README snippet

Example prompts:

"Create API tests for the /api/users endpoint"
"Scaffold a Pact contract test between the frontend and the auth service"
"Generate request/response tests for our REST API at https://api.myapp.com"

Trigger in VS Code:

@api-testing Create contract tests for the /api/jobs endpoint at https://wesendcv.com/api/jobs

---

📝 Manual Testing Chatmode — Step-by-Step Checklists

When to use: You need a human-executable test checklist, or you want to guide a QA tester through a manual regression run.

What it does: Provides structured, step-by-step manual test procedures for the WeSendCV site (or any configured target), including:

• Landing page and navigation verification
• Form submission flows
• Visual and performance checks
• Cross-browser and mobile checklist

Example prompts:

"Give me a manual testing checklist for the WeSendCV homepage"
"How do I manually verify the login flow?"
"What's the regression checklist for UI testing?"

Trigger in VS Code:

@manualtesting Provide a manual regression checklist for https://wesendcv.com

---

🔍 Code Reviewer Agent — Audit Test Quality

When to use: You want to review a spec or page object for POM compliance, security issues, missing coverage, or Playwright anti-patterns before merging.

What it does:

1. Reads target file(s) in tests/ fully before evaluating
2. Checks all selectors are in tests/pages/ — not inline in specs
3. Flags waitForTimeout, brittle XPath, hardcoded credentials, and missing negative tests
4. Produces a severity-ranked markdown report (🔴 Critical / 🟡 Warning / 🔵 Suggestion)
5. Optionally applies fixes directly when asked (moves selectors to Page Objects, removes anti-patterns)

Example prompts:

"Review tests/wesendcv.spec.ts for code quality"
"Audit all files under tests/security-tests/ before this PR merges"
"Check tests/pages/WeSendCVPage.ts for POM compliance"
"Fix the critical issues you found in the review"

Trigger in VS Code:

@code-reviewer Review tests/wesendcv.spec.ts for POM compliance, security, and best practices

🛠️ Playwright Test Debugging Skill

Location: .github/skills/playwright-test-debugging/SKILL.md

Unlike the chatmodes above (which you invoke manually), this skill is loaded automatically by Copilot when it detects you are debugging a test failure. You do not need to select it explicitly.

What it teaches Copilot:

• Where to find test results (test-results/results.json, junit.xml, playwright-report/)
• How to identify failure types: selectors, timing, visual regression, network, accessibility
• How to reproduce failures locally with PowerShell commands
• Anti-patterns to avoid (hard sleeps, raw selectors in test files, etc.)
• POM-aware fix strategies specific to this repository's structure

Auto-triggered by prompts like:

"The wesendcv test is failing with a timeout"
"Debug the accessibility test failures in CI"
"Why is the vibe spec failing on Windows?"

---

📐 Code Review Skill

Location: .github/skills/code-review/SKILL.md

Like the debugging skill, this skill is loaded automatically by Copilot when it detects you are reviewing, auditing, or inspecting test code. You do not need to select it explicitly.

What it teaches Copilot:

• POM compliance rules (selectors in tests/pages/, data in tests/data/)
• Playwright anti-patterns to flag (waitForTimeout, positional XPath, networkidle misuse)
• Security rules aligned to OWASP Top 10 (no hardcoded secrets, safe XSS payloads)
• Coverage completeness expectations (negative tests, a11y, performance counterparts)
• Severity-ranked report format (🔴 Critical / 🟡 Warning / 🔵 Suggestion)

Auto-triggered by prompts like:

"Review this test file"
"Audit tests/security-tests/ for issues"
"Is this Page Object following best practices?"

---

Using Agents with the MCP Flow

For fully programmatic agent usage (no VS Code UI), start the Playwright MCP server and send chatmode prompts via API:

# Start MCP server
npx playwright run-test-mcp-server

# Or add as an npm script
npm set-script mcp:start "npx playwright run-test-mcp-server"
npm run mcp:start

The .vscode/mcp.json file pre-configures the MCP entrypoint for VS Code's agent runtime. See the Using Chatmode prompts and the MCP flow section for API-level usage examples.

Best Practices & Tips

• Selectors: Use stable id or data-test attributes instead of brittle CSS/XPath.
• Page Objects: Keep POM methods focused on single actions; avoid god-methods.
• Test Data: Extract URLs, credentials, and fixtures into tests/data/ files.
• Artifacts: Enable traces and screenshots in playwright.config.ts for faster triage.
• Baselines: Keep one baseline per viewport/OS if visual differences are expected.
• Isolation: Tests should be independent and idempotent; avoid test-to-test dependencies.
• No hard sleeps: Use Playwright's built-in waits (waitForSelector, waitForNavigation, etc.).
• Negative tests: Always validate error paths and edge cases alongside happy paths.

How to Extend

Add a New Page Object

1. Create tests/pages/MyPage.ts
2. Import page data from tests/data/
3. Define locators as class properties
4. Implement action methods (goto, click, fill, verify, etc.)
5. Export the class for use in test specs

Example:

// tests/pages/LoginPage.ts
import { Page, expect } from '@playwright/test';
import { URLS } from '../data/urls';

export class LoginPage {
  constructor(readonly page: Page) {}
  
  async gotoLoginPage() {
    await this.page.goto(URLS.app.login);
  }
  
  async login(username: string, password: string) {
    await this.page.fill('[data-test="username"]', username);
    await this.page.fill('[data-test="password"]', password);
    await this.page.click('[data-test="login-btn"]');
  }
}

Add Test Data

1. Create tests/data/mydata.ts
2. Export constants (URLs, users, products, etc.)
3. Import and use in page objects and test specs

Example:

// tests/data/users.ts
export const TEST_USERS = {
  standard: {
    username: 'standard_user',
    password: 'secret_sauce',
  },
  admin: {
    username: 'admin',
    password: 'admin_pass',
  },
};

Add a New Test

1. Create tests/myfeature.spec.ts
2. Import page objects and test data
3. Use test.beforeEach() to initialize page objects
4. Write test cases focusing on workflow and assertions
5. Run: npx playwright test tests/myfeature.spec.ts

Common Commands

# Install
npm install
npx playwright install --with-deps

# Test
npm test                           # Full suite
npm run test:ci                    # CI-style run
npx playwright test --headed       # Debug mode
npx playwright test --debug        # Step through with Inspector

# Dev
node tools/dev-server.js           # Start demo server
node tools/compare.js [...]        # Run perceptual diff

# Clean
npm run clean                      # Remove artifacts (if script exists)

Troubleshooting

Issue	Solution
Tests timeout on Windows	Increase timeouts in playwright.config.ts or run with --retries=1
Visual diffs fail unexpectedly	Review artifacts/diff.png and artifacts/current.png, update baseline if change is approved
Flaky selectors	Use data-test attributes, increase wait timeouts, avoid nth-child selectors
Browser install fails	Run npx playwright install --with-deps to include OS-level dependencies
Port 3000 already in use	Modify dev-server.js to use a different port
Page Object not found	Ensure import path matches file location (e.g., ./pages/WeSendCVPage)

Using Chatmode prompts and the MCP flow

See the AI Agents — Chatmodes & Skills section for a full guide on each agent and how to activate it in VS Code.

Quick: use a chatmode prompt directly with an LLM API (PowerShell + OpenAI):

$env:OPENAI_API_KEY = "sk_..."
$prompt = Get-Content ".github/chatmodes/🎭 healer.chatmode.md" -Raw
curl -s https://api.openai.com/v1/chat/completions `
  -H "Authorization: Bearer $env:OPENAI_API_KEY" `
  -H "Content-Type: application/json" `
  -d (@{ model = "gpt-4o-mini" ; messages = @(@{ role = "user"; content = $prompt }) } | ConvertTo-Json)

Security: Never commit API keys. Use environment variables or CI secrets.
