### Start Using Immediately

After setup, just chat naturally with your AI:

```
💬 You: "Generate tests for calculatePrice function"
🤖 AI: *Creates test file* Generated 15 tests covering: happy path, edge cases (negative prices, zero), error handling, boundary conditions...

💬 You: "Add tests for the UserService class"
🤖 AI: Created UserService.test.js with: 8 unit tests, 4 integration tests, mocked dependencies, 95% coverage...

💬 You: "What test cases am I missing for login.js?"
🤖 AI: Missing: Invalid email format, expired tokens, rate limiting, concurrent sessions, SQL injection attempts...
```

## ✨ Features
