+# Test Plan — Nova Registration Form
+
+## 1. Test Objective
+Verify the correctness of field validation on the registration form (username, email, password, confirm password, age, terms agreement) and identify defects in the validation logic.
+
+## 2. Test Item
+`index.html` — a single-page registration form (client-side JavaScript validation, no backend).
+
+## 3. In Scope
+- Username field validation
+- Email field validation
+- Password and Confirm Password field validation
+- Age field validation
+- Terms of Service checkbox validation
+- Display of error messages and the success banner
+
+## 4. Out of Scope
+- Server-side validation and data persistence (no backend)
+- Cross-browser testing (Chrome only)
+- Performance and security testing
+
+## 5. Test Techniques
+- Boundary Value Analysis — "Age" field
+- Equivalence Partitioning — "Email" field
+- Pairwise Testing — "Password" / "Confirm Password" / "Age" field combinations
+- Functional checklist testing
+
+## 6. Test Environment
+- Browser: Chrome (latest stable)
+- OS: any (Windows / macOS / Linux)
+- Device: desktop
+
+## 7. Entry Criteria
+- The `index.html` page is accessible and loads in the browser with no console errors
+
+## 8. Exit Criteria
+- All planned test cases have been executed
+- All identified defects are documented in bug reports
+
+## 9. Deliverables
+- Test cases: `test-cases/`
+- Bug reports: `bug-reports/`
+
+## 10. Risks
+- The absence of a backend limits testing to client-side validation only
