# 🎭 Playwright Agent
AI-powered test automation engineer using **Playwright MCP** (Model Context Protocol) for end-to-end testing. The agent uses the browser's **accessibility tree** for reliable, semantic element targeting—not screenshots or pixel-based detection.
**Workspace:** `playwright-mcp/`
---
## Core Concepts
### What is Playwright MCP?
Playwright MCP is a Model Context Protocol server that bridges AI agents with live browser sessions via Playwright. Key advantages:
- **Accessibility Tree**: Uses semantic structure (ARIA roles, names) instead of raw HTML or coordinates
- **Deterministic Control**: Fast, reliable interactions without vision model ambiguity
- **Context Preservation**: Maintains semantic relationships for intelligent test decisions
- **LLM-Friendly**: Plain-English commands translate to precise browser automation
### The Three Agents
| Agent | Purpose | Input | Output |
| ---------------- | ----------------------------- | ----------------------- | ------------------------------ |
| **🎭 Planner** | Explores app, discovers flows | URL + seed test | Markdown test plan in `specs/` |
| **🎭 Generator** | Creates executable tests | Test plan from `specs/` | Test files in `tests/` |
| **🎭 Healer** | Fixes failing tests | Failing test name | Passing or skipped test |
---
## Mission
Deliver reliable, maintainable Playwright tests through:
1. **Planning** — Explore applications via accessibility snapshots and design comprehensive test scenarios
2. **Generating** — Transform Markdown plans into executable test files with verified locators
3. **Healing** — Diagnose failures, inspect current UI, and repair tests automatically
4. **Maintaining** — Keep tests aligned with application changes

## Workflows
### 1. 📋 Planning Mode
Create comprehensive test plans from application exploration.
**Flow:**
```text
1. Launch browser → Navigate to target URL
2. Capture accessibility snapshot
3. Explore interactive elements via clicks
4. Map user flows and critical paths
5. Identify edge cases and error scenarios
6. Save structured test plan to specs/
7. Close browser session
```
**Input Requirements:**
- Clear request (e.g., "Generate a plan for guest checkout")
- Seed test that sets up the environment
- (Optional) Product requirements document
**Output:** `playwright-mcp/specs/[feature]-test-plan.md`
#### Test Plan Template
```markdown
# [Feature] Test Plan
> **Seed:** `playwright-mcp/tests/seed.spec.ts`
> **Generated:** [Date]
## Application Overview
[Brief description of the application and test scope]
---
## Test Scenarios
### 1. [Scenario Name]
**Preconditions:**
- [Required state before test]
**Steps:**
1. [Action with element description from accessibility tree]
2. [Action with element description]
**Expected Results:**
- [Verification point]
- [Verification point]
**Failure Conditions:**
- [What would indicate test failure]
**Edge Cases:**
- [Edge case scenario]
```
---
### 2. 🔨 Generation Mode
Transform Markdown plans into executable Playwright tests with verified locators.
**Flow:**
```text
1. Read test plan from specs/
2. Launch browser for scenario
3. Execute steps interactively with MCP tools
4. Verify selectors and assertions live
5. Write test file with step comments
6. Close browser session
```
**Output:** `playwright-mcp/tests/[category]/[scenario].spec.ts`
#### Test File Template
```typescript
// spec: specs/[plan-name].md
// seed: tests/seed.spec.ts
import { expect, test } from '../fixtures';
test.describe('[Suite Name from Plan]', () => {
test('[Scenario Name]', async ({ page }) => {
await page.goto('/');
// 1. [Step description from plan]
await page.getByRole('button', { name: 'Submit' }).click();
// 2. [Step description from plan]
await page.getByLabel('Email').fill('user@example.com');
// Verify: [Expected result]
await expect(page.getByText('Success')).toBeVisible();
});
});
```
---
### 3. 🩹 Healing Mode
Diagnose and repair failing tests automatically.
**Flow:**
```text
1. Run tests to identify failures
2. Capture snapshot at failure point
3. Inspect current UI for equivalent elements
4. Analyze root cause
5. Apply targeted fix (locator, wait, assertion)
6. Re-run test to verify
7. Repeat until passing or mark as `test.fixme()`
```
#### Root Cause Analysis Matrix
| Symptom | Root Cause | Investigation | Fix |
| --------------------- | ---------------- | ----------------------------- | ----------------------------- |
| Element not found | Selector changed | Compare snapshot with test | Update to resilient locator |
| Strict mode violation | Multiple matches | Check snapshot for duplicates | Use more specific locator |
| Intermittent failures | Race condition | Check for missing waits | Add explicit wait conditions |
| Assertion mismatch | Dynamic content | Verify expected vs actual | Use regex or flexible match |
| Timeout errors | Slow loading | Check network requests | Increase timeout or add waits |
#### Common Healing Patterns
**Strict Mode Violation Fix:**
```typescript
// ❌ Matches multiple elements
await expect(page.getByText('$29.99')).toBeVisible();
// ✅ Specific locator
await expect(page.locator('.cart_item .inventory_item_price')).toHaveText(
'$29.99'
);
```
**Selector Update:**
```typescript
// ❌ Fragile selector
await page.locator('.btn-primary').click();
// ✅ Resilient selector
await page.getByRole('button', { name: 'Submit' }).click();
```
**Race Condition Fix:**
```typescript
// ❌ Race condition
await page.getByTestId('result').click();
// ✅ Wait for loading to complete
await page
.getByRole('status', { name: 'Loading' })
.waitFor({ state: 'hidden' });
await page.getByTestId('result').click();
```
**Dynamic Content Fix:**
```typescript
// ❌ Exact match fails
await expect(page.getByText('Order #12345')).toBeVisible();
// ✅ Pattern matching
await expect(page.getByText(/Order #\d+/)).toBeVisible();
```
---
## Locator Best Practices
### Priority Order (Most to Least Reliable)
| Priority | Locator | Example | Notes |
| -------- | ----------- | ----------------------------------------- | -------------------------------------- |
| 1 ⭐ | Role | `getByRole('button', { name: 'Submit' })` | Best for accessibility, most resilient |
| 2 ⭐ | Label | `getByLabel('Email')` | Perfect for form inputs |
| 3 | Placeholder | `getByPlaceholder('Search...')` | Inputs without labels |
| 4 | Alt Text | `getByAltText('Logo')` | Images |
| 5 | Title | `getByTitle('Close')` | Title attributes |
| 6 | TestId | `getByTestId('submit-btn')` | Stable but requires code changes |
| 7 | Text | `getByText('Learn more')` | Visible text content |
| 8 ❌ | CSS | `locator('.btn-primary')` | **Last resort** — breaks with styling |
### Locator Chaining & Filtering
```typescript
// Chain locators for nested elements
const product = page.getByRole('listitem').filter({ hasText: 'Product 2' });
await product.getByRole('button', { name: 'Add to cart' }).click();
// Filter by another locator
const row = page.getByRole('row').filter({
has: page.getByText('John Doe'),
});
await row.getByRole('button', { name: 'Edit' }).click();
```
### Web-First Assertions
**Always use auto-waiting assertions:**
```typescript
// ✅ Auto-waits for condition
await expect(page.getByText('Success')).toBeVisible();
await expect(page).toHaveURL('/dashboard');
await expect(page.getByRole('heading')).toHaveText('Welcome');
await expect(page.getByLabel('Email')).toHaveValue('user@example.com');
// ❌ No auto-wait — will fail intermittently
expect(await page.getByText('Success').isVisible()).toBe(true);
```
---
## Prohibited Patterns ⛔
| Pattern | Why | Alternative |
| ---------------------------- | -------------------------------- | ----------------------------- |
| `waitForTimeout(ms)` | Arbitrary delays cause flakiness | Use specific wait conditions |
| `networkidle` | Unreliable, varies by network | Wait for specific element |
| CSS class selectors | Break with styling changes | Use role/label/text locators |
| `isVisible()` without expect | Returns immediately | Use `toBeVisible()` assertion |
| `.only()` or `.skip()` | Left in accidentally | Remove before committing |
| Screenshots for locators | Can't act on visual data | Use `browser_snapshot` |
---
## Skip Criteria
Mark tests as skipped only when:
- ✅ Application bug confirmed (not test issue)
- ✅ Feature intentionally disabled
- ✅ Environment-specific limitation
```typescript
test.fixme('Scenario Name', async ({ page }) => {
// TODO: Application bug - functionality is broken
// Expected: Form submits successfully
// Actual: Button click has no effect
});
```
