How the Brain Works

The Thinking Loop

OpenQA's Brain operates in a continuous loop of analysis, thinking, action, and learning:

┌───────────┐     ┌───────────┐     ┌───────────┐
│  ANALYZE  │ →→→ │   THINK   │ →→→ │    ACT    │
└───────────┘     └───────────┘     └───────────┘
     │                  │                  │
     │                  │                  │
     └──────────────────┴──────────────────┘

What the Brain Does

1. Application Analysis

When you provide your SaaS configuration, the Brain:

• Parses your application description to understand its purpose
• Identifies key features and user flows
• Detects potential risk areas (forms, payments, auth)
• If a repo is connected, analyzes code structure and dependencies

2. Test Strategy Planning

Based on the analysis, the Brain creates a testing strategy:

• Prioritizes critical paths (checkout, login, signup)
• Identifies security-sensitive areas for penetration testing
• Plans regression tests for known bug-prone areas
• Schedules performance tests for heavy pages

3. Dynamic Agent Creation

The Brain creates specialized agents on-the-fly:

🧠 Brain: "I see this app has a checkout flow. Let me create a specialist."
     ↓
🤖 Creates: "Checkout Flow Tester" agent with custom prompt
     ↓
🧪 Agent generates: 5 tests for cart, payment, confirmation
     ↓
✅ Executes tests, reports 2 bugs found

4. Continuous Improvement

After each test session, the Brain:

• Analyzes which tests failed and why
• Identifies flaky tests and marks them for review
• Discovers new areas to test based on findings
• Updates its understanding of the application

Triggering the Brain

Manual Trigger

# Start a full autonomous session
curl -X POST http://localhost:3000/api/brain/run

# Just analyze without running tests
curl -X POST http://localhost:3000/api/brain/analyze

Automatic Triggers

The Brain can be triggered automatically:

• On merge - When code is merged to main branch
• On deploy - After a successful CI/CD pipeline
• On schedule - At regular intervals (configurable)
