# Authentication Feature - Implementation Plan

**Feature**: FOB-AUTH-LOGIN-1 Authentication and Login  
**Feature File**: `docs/features/act-0-auth/authentication.feature`  
**GitHub Issues**: #7, #8, #9, #10, #11 (AUTH-01 through AUTH-05)  
**Branch**: `feature/auth-scenarios`

---

## Current State Assessment

### ✅ What Exists (Reusable)

1. **Login View (Partial)** - `accounts/views.py::CustomLoginView`
   - Uses Django's `AuthenticationForm` ⚠️ (violates SAO.md "no Django Forms" rule)
   - Session management with remember me (30 days / 2 weeks)
   - Proper logging
   - **Decision**: Rebuild to use custom template validation

2. **Login Template** - `templates/accounts/login.html`
   - Bootstrap 5 styled
   - Has `data-testid` attributes
   - **Decision**: Keep structure, remove Django Form dependencies

3. **Logout View** - `accounts/views.py::custom_logout_view`
   - ✅ Fully implemented and correct
   - **Decision**: Keep as-is

4. **Settings Configuration**
   - LOGIN_URL, LOGIN_REDIRECT_URL configured
   - Session settings configured
   - **Decision**: Update URLs to match convention

5. **Base Template** - `templates/base.html`
   - Bootstrap 5.3.8 + Font Awesome + HTMX
   - **Decision**: Reuse for all auth templates

### ❌ What's Missing

1. **Custom User Model** - Using Django's default User
2. **Registration Views/Templates** - AUTH-03
3. **Password Reset Flow** - AUTH-04  
4. **Dashboard Stub** - FOB-DASHBOARD-1
5. **Onboarding Stub** - FOB-ONBOARDING-1
6. **Integration Tests** - All scenarios
7. **URL Convention Compliance** - `/auth/user/` pattern

### ⚠️ Issues to Fix

1. **URL Pattern**: `/accounts/` → `/auth/` (violates convention)
2. **Django Forms**: Remove `AuthenticationForm`, use manual validation
3. **Missing Stubs**: Dashboard and onboarding pages needed

## Clarification Questions

### Q1: User Model
**Question**: SAO.md says "extends Django's standard User model" but no custom fields specified. Start with built-in User?  
**Answer**: YES - Use Django's built-in User. Email field already exists. Can extend later if needed.

### Q2: Email-based Login
**Question**: Login form shows "Username" but docs mention email. Use username or email?  
**Answer**: KEEP USERNAME - Django's default. Email-based login is future enhancement.

### Q3: Password Reset Email
**Question**: AUTH-04 requires "receives a reset link". Use console email backend for MVP?  
**Answer**: YES - Console backend for now. SMTP later.

  - Update: GitHub issue #11 (mark complete)

---

### Phase 6: Testing Implementation ✅ COMPLETE

**Purpose**: Comprehensive testing per two-tier strategy (Tier 1 sufficient for AUTH feature)

**Note**: Two-tier testing strategy exists per `/dev-4-1-feature-at` and `/dev-4-2-journey-certification`. For AUTH feature, **Tier 1 provides complete coverage**. Tier 2 (browser-based) reserved for future features with heavy HTMX/JavaScript.

#### Tier 1: Feature Acceptance Tests (AT) ✅ COMPLETE (SATISFIES PHASE 6)

- [x] **6.1** Feature-level integration tests with Django Test Client
  - **Files**: 
    - `tests/integration/test_auth_login.py` (8 tests) ✅
    - `tests/integration/test_auth_registration.py` (9 tests) ✅
    - `tests/integration/test_auth_password_reset.py` (8 tests) ✅
    - `tests/integration/test_auth_logout.py` (5 tests) ✅
  - **Tool**: Django Test Client (fast, reliable)
  - **Coverage**: ALL scenarios from authentication.feature
  - **Status**: 29 tests passing in 3.5s
  - **Per workflow**: `.windsurf/workflows/dev-4-1-feature-at.md`

- [x] **6.2** E2E journey tests with Django Test Client
  - **File**: `tests/e2e/test_auth_e2e.py` (5 tests) ✅
  - **Tool**: Django Test Client (not browser-based yet)
  - **Coverage**: Complete user journeys
    1. New user registration → onboarding → dashboard
    2. Login with invalid then valid credentials
    3. Password reset complete flow
    4. Logout and access control
    5. Registration validation errors
  - **Status**: 5 tests passing in 1.5s

#### Tier 2: Journey Certification (Browser-Based) � NOT PART OF AUTH IMPLEMENTATION

**Status**: Not implemented for AUTH feature (not needed)

**Rationale**: 
- AUTH feature has minimal JavaScript/HTMX interactions
- Tier 1 tests provide complete scenario coverage (34 tests)
- Django Test Client validates all authentication logic, redirects, sessions
- No visual/UI complexity requiring browser validation

**Future Use**:
- **When needed**: Features with heavy HTMX (e.g., dashboard navigation, dynamic workflow updates)
- **Tool**: LiveServerTestCase + Playwright
- **Per workflow**: `.windsurf/workflows/dev-4-2-journey-certification.md`
- **Example**: Dashboard navigation with HTMX tab switching would benefit from Tier 2 tests

**This is guidance for FUTURE features, not a requirement for AUTH completion.**

## Test Summary

### Unit Tests
- `tests/unit/test_auth_config.py` - ✅ Already exists

### Tests Implemented for AUTH Feature ✅ COMPLETE

**Tier 1: Feature Acceptance Tests (Django Test Client)**
- `tests/integration/test_auth_login.py` - AUTH-01, AUTH-02 (8 tests) ✅
- `tests/integration/test_auth_registration.py` - AUTH-03 (9 tests) ✅

**Per workflow**: `.windsurf/workflows/dev-4-1-feature-at.md`

### Tier 2: Not Implemented for AUTH (Not Needed) 📋

**Tier 2** (browser-based with LiveServerTestCase + Playwright) is **not part of AUTH implementation**.

**Why not needed**:
- AUTH has minimal JavaScript/HTMX
- Tier 1 provides complete coverage
- No visual/UI complexity requiring browser validation

**When to use Tier 2**: Future features with heavy HTMX/JavaScript interactions
**Per workflow**: `.windsurf/workflows/dev-4-2-journey-certification.md`

**Total Tests Implemented for AUTH**: 34 test functions

---

## Success Criteria

- ✅ All 5 authentication scenarios pass integration tests
- ✅ No Django Forms used (per SAO.md)
- ✅ URL conventions followed (`/auth/user/*`)
- ✅ Dashboard and onboarding stubs in place
- ✅ Bootstrap toasts for success messages
- ✅ Field-level validation errors per IA guidelines
- ✅ Font Awesome icons and tooltips on all buttons
- ✅ All `data-testid` attributes present for testing
- ✅ Extensive logging per project rules
- ✅ Test coverage > 90% for accounts app
- ✅ Issues #7-11 marked complete

---

## Dependencies

**Python Packages** (already in requirements.txt):
- Django 5.2.8
- pytest-django
- No additional packages needed

**Documentation References**:
- `docs/architecture/SAO.md` - Architecture patterns
- `docs/ux/IA_guidelines.md` - UI/UX patterns
- `.windsurf/rules/*.md` - Development rules

---

## Estimated Scope

- **5 Scenarios**: AUTH-01 through AUTH-05
- **2 Stub Pages**: Dashboard, Onboarding
- **6 Views**: Login, logout, register, password_reset (2 views), dashboard, onboarding
- **6 Templates**: Login, register, password_reset (2), email, dashboard, onboarding  
- **7 Test Files**: ~20 test functions total
- **URL Updates**: Restructure to `/auth/user/` pattern

**Complexity**: Medium (login already exists, need to rebuild without Forms)
