## Example Interactions

**User:** Create a test plan for a user registration form with email, password, and confirm password fields.

**Agent:**

### Test Plan: User Registration

**Scope:** Registration form with email, password, confirm password
**Environment:** Chrome 120, Firefox 121, Safari 17, mobile viewport

#### Happy Path Tests

| ID | Test Case | Input | Expected Result |
|----|-----------|-------|----------------|
| R-01 | Valid registration | valid@email.com, StrongPass1! | Account created, redirect to dashboard |
| R-02 | Login after registration | Same credentials | Successful login |

#### Edge Case Tests

| ID | Test Case | Input | Expected Result |
|----|-----------|-------|----------------|
| R-03 | Email with subdomain | user@sub.domain.com | Accepted |
| R-04 | Email with plus alias | user+tag@gmail.com | Accepted |
| R-05 | Maximum length email | 254-char valid email | Accepted |
| R-06 | Password at minimum length | Exactly 8 characters | Accepted |
| R-07 | Password at maximum length | 128 characters | Accepted |

#### Negative Tests

| ID | Test Case | Input | Expected Result |
|----|-----------|-------|----------------|
| R-08 | Empty email | (blank) | "Email required" error |
| R-09 | Invalid email format | "notanemail" | "Invalid email" error |
| R-10 | Password too short | 7 characters | "Minimum 8 characters" error |
| R-11 | Passwords don't match | Different values | "Passwords must match" error |
| R-12 | Duplicate email | Existing email | "Email already registered" error |
| R-13 | SQL injection in email | `' OR 1=1 --` | Sanitized, error shown |
| R-14 | XSS in name field | `<script>alert(1)</script>` | Escaped, no execution |

**Total:** 14 cases (2 happy, 5 edge, 7 negative)

**User:** I found a bug — the form accepts passwords without special characters even though it should require them.

**Agent:**

### Bug Report: BUG-001

| Field | Detail |
|-------|--------|
| **Title** | Registration accepts passwords without special characters |
| **Severity** | High |
| **Priority** | P1 |
| **Component** | Registration Form — Password Validation |
| **Environment** | Chrome 120 / macOS 14.2 |

**Steps to Reproduce:**
1. Navigate to /register
2. Enter valid email: test@example.com
3. Enter password: `Abcdefg1` (letters + number, no special character)
4. Enter same in confirm password
5. Click "Register"

**Expected:** Validation error "Password must include a special character"
**Actual:** Account created successfully

**Impact:** Users can create weak passwords that do not meet security policy. Existing accounts with weak passwords may be vulnerable.

**Suggested Fix:** Add regex check for at least one special character (`!@#$%^&*`) in password validation on both client and server side.
