## Story Description
|
|
|
|
**As a** System Administrator
|
|
**I want** to validate user email addresses
|
|
**So that** only users with valid email formats can register
|
|
|
|
### Context
|
|
|
|
This is a foundational feature for user registration. We need robust email validation that follows RFC standards while being user-friendly. This will be used by the registration system and user profile updates.
|
|
|
|
## Acceptance Criteria
|
|
|
|
```gherkin
|
|
Feature: User Email Validation
|
|
|
|
Scenario: Valid email formats are accepted
|
|
Given a user provides an email address
|
|
When the email has correct format with @ symbol and domain
|
|
Then the validation should return true
|
|
|
|
Scenario: Invalid email formats are rejected
|
|
Given a user provides an invalid email address
|
|
When the email lacks @ symbol or proper domain format
|
|
Then the validation should return false with appropriate error message
|
|
|
|
Scenario: Edge cases are handled properly
|
|
Given a user provides edge case email formats
|
|
When validation is performed on emails with special characters or unusual formats
|
|
Then the system should handle them according to RFC standards
|
|
```
|
|
|
|
## Technical Requirements
|
|
|
|
### Functional Requirements
|
|
|
|
- Validate email format using RFC-compliant rules
|
|
- Return boolean result with error details when invalid
|
|
- Handle common edge cases (special characters, multiple @, etc.)
|
|
- Performance: validation should complete in < 1ms
|
|
|
|
### Non-Functional Requirements
|
|
|
|
- **Performance:** < 1ms validation time per email
|
|
- **Security:** Prevent injection attacks via email input
|
|
- **Reliability:** 99.9% accuracy on email format validation
|
|
- **Maintainability:** Clear error messages for debugging
|
|
|
|
## TDD Test Plan (QA Agent Responsibility)
|
|
|
|
### Test Strategy
|
|
|
|
- **Primary Test Type:** unit
|
|
- **Mocking Approach:** No external dependencies to mock
|
|
- **Test Data:** Fixed test cases covering valid/invalid formats
|
|
|
|
### Planned Test Scenarios
|
|
|
|
| ID | Scenario | Type | Priority | AC Reference |
|
|
| ------ | ---------------------------- | ---- | -------- | ------------ |
|
|
| UV-001 | Valid email formats accepted | unit | P0 | AC1 |
|
|
| UV-002 | Invalid formats rejected | unit | P0 | AC2 |
|
|
| UV-003 | Edge cases handled | unit | P1 | AC3 |
|
|
| UV-004 | Performance requirements met | unit | P2 | NFR |
|
|
|
|
## TDD Progress
|
|
|
|
### Current Phase: RED
|
|
|
|
**Cycle:** 1
|
|
**Last Updated:** 2025-01-12
|
|
|
|
### Red Phase - Cycle 1
|
|
|
|
**Date:** 2025-01-12
|
|
**Agent:** Quinn (QA Agent)
|
|
|
|
**Tests Written:**
|
|
|
|
- UV-001: should validate correct email format (FAILING ✅)
|
|
- UV-002: should reject invalid email format (FAILING ✅)
|
|
- UV-003: should handle edge cases (FAILING ✅)
|
|
|
|
**Test Files:**
|
|
|
|
- tests/user-validator.test.js
|
|
|
|
**Next Step:** Dev Agent to implement minimal code to make tests pass
|
