# Mabl Expert

AI-powered end-to-end testing with self-healing capabilities.

## What Makes Mabl Special?

- **Self-Healing Tests**: AI adapts to UI changes automatically
- **Low-Code Builder**: Record tests visually
- **AI Insights**: Automatic root cause analysis
- **Cross-Browser**: Chrome, Firefox, Safari, Edge
- **Mobile Web**: Responsive testing built-in

## Pricing (2026)

- **Pro**: $500+/month
- **Enterprise**: Custom pricing
- Best for: Teams with frequent UI changes

## When to Use Mabl

### Good Fit
- Frequently changing UI
- Non-technical QA team
- Need visual test recording
- High test maintenance burden

### Not Ideal
- Simple static sites
- Budget constraints (expensive!)
- Need mobile native testing
- API-only testing

## Key Features

### 1. Self-Healing
```
Traditional: Selector changed → Test fails
Mabl: Selector changed → AI finds new selector → Test passes
```

### 2. Visual Recording
- Point and click to create tests
- Assertions added visually
- No code required for basic tests

### 3. API Testing
```javascript
// Mabl can also test APIs
api.request('POST', '/users')
  .body({ name: 'Test User' })
  .expect(201)
  .extractJson('$.id', 'userId');
```

## CI/CD Integration

### GitHub Actions
```yaml
- name: Run Mabl Tests
  uses: mablhq/github-run-tests-action@v1
  with:
    api-key: ${{ secrets.MABL_API_KEY }}
    application-id: your-app-id
    environment-id: your-env-id
```

### Deployment Events
```bash
# Notify mabl of deployment
curl -X POST "https://api.mabl.com/events/deployment" \
  -H "Authorization: Bearer $MABL_API_KEY" \
  -d '{
    "environment_id": "env-123",
    "application_id": "app-456"
  }'
```

## Alternatives for Budget-Conscious

### Playwright + AI (DIY Self-Healing)
```typescript
// Use AI to find elements when selector fails
async function smartClick(page, selectors) {
  for (const selector of selectors) {
    try {
      await page.click(selector, { timeout: 1000 });
      return;
    } catch (e) {
      continue;
    }
  }
  // Fall back to AI vision
  const screenshot = await page.screenshot();
  const element = await aiVision.findElement(screenshot, 'login button');
  await page.click(element.selector);
}
```

### Playwright + Claude Vision
```typescript
// Screenshot-based testing (vibe coder friendly)
const screenshot = await page.screenshot();
const analysis = await claude.vision.analyze(screenshot,
  "Is the login form visible and properly styled?"
);
```

## Best Practices

### 1. Use Data-TestIDs
```html
<!-- Even with AI, good selectors help -->
<button data-testid="submit-btn">Submit</button>
```

### 2. Group Related Tests
```
Flows/
├── Authentication/
│   ├── Login
│   └── Logout
├── Checkout/
│   ├── Add to Cart
│   └── Complete Purchase
```

### 3. Set Up Environments
```
Development → Staging → Production
(run on each deploy)
```

Use when: High-budget teams, frequent UI changes, low-code QA needs

Overview

This skill describes Mabl Expert, an AI-powered end-to-end testing solution that combines self-healing tests, a low-code test builder, and automated root-cause insights. It targets teams that need reliable UI testing across browsers and responsive mobile web without heavy test maintenance. The skill highlights integration points, pricing considerations, and practical alternatives for cost-sensitive teams.

How this skill works

Mabl uses AI to detect UI changes and automatically update selectors so tests keep running when the app evolves. Tests can be recorded visually with a low-code builder, enriched with assertions, and executed across Chrome, Firefox, Safari, Edge, and mobile web. It also supports API checks and integrates with CI/CD pipelines to run tests on deployments and surface actionable failure analysis.

When to use it

  • Your UI changes frequently and tests break often
  • QA teams are non-technical or prefer low-code tools
  • You need cross-browser and responsive web coverage without a large automation team
  • You want automated root-cause analysis to speed triage and reduce manual debugging
  • You have budget for a hosted, enterprise-grade testing platform

Best practices

  • Add stable data-testids to critical elements to improve reliability even with self-healing
  • Group tests by feature flows (authentication, checkout, etc.) to simplify maintenance and reporting
  • Run suites per environment (dev → staging → production) and trigger on deployment events
  • Use API tests alongside UI flows to isolate failures faster
  • Monitor cost vs. value and consider hybrid approaches for high-volume/smaller-budget scenarios

Example use cases

  • A customer-facing web app with frequent UI updates that needs continuous regression coverage
  • Non-engineer QA teams recording visual tests for common purchase or signup flows
  • Integrating end-to-end tests into GitHub Actions to gate releases and notify on deployment events
  • Combining API checks and UI flows to validate end-to-end transactions
  • Replacing fragile selector-based suites with AI-driven self-healing tests to reduce maintenance time

FAQ

Does Mabl support native mobile app testing?

No. Mabl focuses on mobile web responsiveness; native mobile app testing is not a primary capability.

Is Mabl a good option for small, budget-conscious teams?

Mabl is powerful but relatively expensive. For tight budgets, consider Playwright plus AI-assisted self-healing patterns as a cost-effective alternative.
