## Where to Look
| Task | Location | Notes |
|------|----------|-------|
| Add a new use case | `app/application/use_cases/` | Follow naming: `{action}_post.py` |
| Add a new API endpoint | `app/presentation/api/v1/posts.py` | Or create new module in `v1/` |
| Add a new web page | `app/presentation/web/routes.py` | Integrate real use cases, not mocks |
| Add a domain entity | `app/domain/entities/` | Inherit from `BaseEntity`, add to `domain/__init__.py` |
| Add a repository method | `app/infrastructure/repositories/post.py` | Mirror in `app/domain/repositories/post.py` |
| Configure DI provider | `app/infrastructure/di/providers.py` | Add to existing provider class or create new one |
| Change database schema | `app/infrastructure/database/models.py` | Mirror changes in domain entity |
| Add/modify tests | `tests/unit/{layer}/` | Mirror `app/` structure exactly |
| Run linting | `uv run ruff check . --fix` | Pre-commit: ruff → ruff format → isort → mypy |
| Run tests | `uv run pytest` | Coverage auto-collected, HTML report at `htmlcov/` |
| Run type check | `uv run mypy .` | Strict mode; excludes `tests/e2e` |

- Use **Repository** pattern for data access
- Use **Dependency Injection** via FastAPI's Depends()
## Anti-Patterns (This Project)
- **NO inline comments** — Self-documenting code only; Google-style docstrings required
- **NO type suppression** — Never use `typing.Any` casts or `# type: ignore` to bypass mypy strict mode
- **Dead code**: `create_container()` in `app/infrastructure/di/container.py` is defined but never used; `main.py` calls `make_async_container()` directly
- **Empty directories**: `app/domain/exceptions/` and `app/presentation/api/deps/` are empty dirs that co-exist with `.py` files of the same name — import ambiguity risk
- **Missing `__main__.py`**: `python -m app` fails; use `uv run blog` or `python app/main.py`
- **Stale config**: `pyproject.toml` excludes `tests/e2e` but the directory does not exist
- **Unused dependency**: `black` is in `[dependency-groups] lints` but never invoked; ruff format is used instead
- **Pre-commit excludes `__init__.py`**: All `__init__.py` files skip linting and import sorting

### Branch Naming
- **Feature**: `feature/{feature-name}` от `dev`
- **Bugfix**: `bugfix/{bug-name}` от `dev`
- **Refactor**: `refactor/{name}` от `dev`
### Test Case IDs
- `TC-UNIT-NNN` — unit тесты (domain, use cases)
- `TC-API-NNN` — API endpoint тесты
- `TC-WEB-NNN` — Web route тесты (HTML responses)
- `TC-E2E-NNN` — End-to-end тесты (Playwright)
### Test Level Selection
Все 4 уровня по умолчанию. Можно сокращать в зависимости от задачи:
- **Domain-only фича**: только TC-UNIT
- **API-only фича**: TC-UNIT + TC-API
- **Web UI фича**: TC-UNIT + TC-WEB + TC-E2E
- **Full-stack фича**: все 4 уровня
- **Bugfix**: уровни в зависимости от слоя бага (минимум unit + regression)
- **Refactor**: все существующие тесты (unit + api + web + e2e)
### Artifact Location
- **Feature**: `pyaqa/feature/TEMPLATE.md` → `pyaqa/feature/{feature-name}.md`
- **Bugfix**: `pyaqa/bugfix/TEMPLATE.md` → `pyaqa/bugfix/{bug-name}.md`
- **Refactor**: `pyaqa/refactor/TEMPLATE.md` → `pyaqa/refactor/{name}.md`
### Commit Rules
При завершении коммитить во ВСЕ затронутые подпроекты:
1. `blog/` — если изменен
2. `pytfm/` — если изменен
3. `pyaqa/` (root) — всегда (обновление ссылок на подпроекты)
## Notes
- Web routes (`app/presentation/web/routes.py`) currently use `MockPost` and `MOCK_POSTS` instead of real use cases — integrate with actual use cases when ready
- `alembic/` directory exists but is non-functional (no `alembic.ini`, no migration scripts)
- `tests/integration/`, `tests/api/`, `tests/e2e/` are documented in architecture but do not exist yet
- `app/domain/roles.py` exists but its symbols are not exported in `app/domain/__init__.py`
- Woodpecker CI uses `.woodpecker/` directory (3 separate YAML files) instead of single `.woodpecker.yml` — valid but non-standard
- CI pipelines have copy-paste boilerplate; `test.yaml` uses `--group tests` while `lint.yaml` and `type.yaml` use `--only-group <X>`

# Web UI Knowledge Base
**Generated:** 2026-05-03 22:15 UTC
**Commit:** 41f2a3d
**Branch:** feature/tests
## Overview
FastAPI Jinja2 web UI layer with Keycloak auth integration, flash messages, and theme support.
## Structure
```
app/presentation/web/
├── __init__.py
├── auth.py # Keycloak OAuth login/logout/callback
├── deps.py # Web dependency injection (current_user, require_auth)
├── error_handlers.py # HTTP exception handlers for web routes
├── flash.py # Flash message middleware
└── routes.py # All web page routes (largest file in project)
```
## Where to Look
| Task | Location |
|------|----------|
| Add a new page | `routes.py` |
| Change auth flow | `auth.py` |
| Change flash messages | `flash.py` |
| Change error pages | `error_handlers.py` |
| Change DI for web | `deps.py` |
## Conventions
- **Templates**: Jinja2 in `app/presentation/templates/`
- **data-testid attributes REQUIRED** on all interactive elements
- **Theme support**: Light/dark via `data-theme` on `<html>`, LocalStorage persistence
- **Auth**: HTTP-only cookie `access_token`, Keycloak integration
- **Mock data**: Routes currently use `MockPost`/`MOCK_POSTS` — integrate real use cases when ready
## Anti-Patterns
- Do NOT use inline comments — self-documenting code only
- Do NOT add external CDN dependencies — all assets must be in `static/`
- Do NOT bypass `filter_visible_posts()` for draft access control
## Notes
- `routes.py` is the largest file in the project (519 lines) — consider splitting by concern
- `home`, `list_posts`, `post_detail`, `new_post_form`, `edit_post_form`, `create_post`, `update_post`, `delete_post`, `profile`, `about` are all defined in `routes.py`
- Web routers are imported directly in `main.py`, bypassing `app/presentation/__init__.py`

# Tests Knowledge Base
**Generated:** 2026-05-03 22:15 UTC
**Commit:** 41f2a3d
**Branch:** feature/tests
## Overview
Unit test suite mirroring DDD layers. 100% unit coverage; integration, API, and E2E test directories are documented but not yet populated.
## Structure
```
tests/
├── conftest.py # Session fixtures (event_loop_policy, playwright)
└── unit/
├── conftest.py # Shared mocks (repository, transaction_manager)
├── test_main.py # App factory, lifespan, CLI entry
├── domain/ # Entity, VO, exception, role tests
├── application/ # Use case tests
└── infrastructure/ # Config, auth, transaction manager tests
```
## Test Model
The project maintains a **feature-based test model** in Markdown files next to the test code.
Agents MUST consult these files before adding or modifying tests.
| Model File | Scope |
|------------|-------|
| [`TEST_MODEL.md`](TEST_MODEL.md) | Global coverage matrix, risk areas, TC-ID conventions |
| [`FEATURE_POST_LIFECYCLE.md`](FEATURE_POST_LIFECYCLE.md) | CRUD, publish, visibility |
| [`FEATURE_RBAC.md`](FEATURE_RBAC.md) | Roles, permissions, access policies |
| [`FEATURE_DOMAIN_FOUNDATION.md`](FEATURE_DOMAIN_FOUNDATION.md) | Entities, value objects, exceptions |
| [`FEATURE_INFRASTRUCTURE.md`](FEATURE_INFRASTRUCTURE.md) | Config, auth client, bootstrap, tx manager |
### Adding a New Test
1. Pick the relevant feature model file.
2. Assign the next available `TC-UNIT-NNN` or `TC-E2E-NNN` ID.
3. Append a test-case entry with **Type**, **Layer**, **File**, **Steps**, **Expected**, and **Last Verified**.
4. If the test closes a gap, update the `Gaps` section and the coverage matrix in `TEST_MODEL.md`.
## Where to Look
| Task | Location |
|------|----------|
| Check coverage before adding tests | `tests/TEST_MODEL.md` |
| Add a domain test | `tests/unit/domain/` |
| Add a use case test | `tests/unit/application/` |
| Add an infra test | `tests/unit/infrastructure/` |
| Add an E2E test | `tests/e2e/` + update relevant `FEATURE_*.md` |
| Shared mock fixtures | `tests/unit/conftest.py` |
## Conventions
- **Class-per-entity/use-case**: `TestPost`, `TestCreatePostUseCase`, etc.
- **asyncio_mode=auto**: `@pytest.mark.asyncio` is redundant but harmless
- **Return types**: All test functions must have `-> None`
- **Coverage gate**: 70% minimum enforced in CI
- **Mock pattern**: `Mock(spec=Interface)` or `MagicMock(spec=Interface)` — project uses both inconsistently
- **Async mocking**: Use `AsyncMock()` for async methods (commit, rollback, repo methods)
## TDD Test Case Workflow
### Adding a Feature Test
1. **User triggers**: `"начем новую фичу"`
2. **Agent analyzes**: существующий код, затронутые слои, рекомендует тесткейсы
3. **User agrees**: подтверждает или корректирует набор тесткейсов
4. **Agent creates**:
- `pyaqa/feature/{feature-name}.md` — артефакт фичи
- Обновляет `FEATURE_*.md` — добавляет новые TC
5. **Agent writes tests**: в порядке TC-UNIT → TC-API → TC-WEB → TC-E2E
6. **Agent marks**: в артефакте статус "tests-ready"
7. **Agent implements**: фичу по слоям (Domain → Application → Infra → Presentation)
8. **Agent verifies**: линтеры, тесты, coverage
9. **User accepts**: подтверждает приемку
10. **Agent commits**: во все затронутые проекты
### Bugfix Test Workflow
1. **User triggers**: `"исправить баг"`
2. **Agent analyzes**: воспроизводит баг, определяет root cause
3. **Agent creates**: `pyaqa/bugfix/{bug-name}.md` — артефакт бага
4. **Agent writes regression test**:
- Unit тест, воспроизводящий баг (должен падать)
- Дополнительные тесты на уровне бага (API/Web/E2E)
5. **Agent fixes**: минимальный фикс
6. **Agent verifies**: все тесты проходят, coverage не упал
7. **User accepts**: проверяет исправление
8. **Agent commits**: во все затронутые проекты
### Refactor Test Workflow
1. **User triggers**: `"отрефакторить"`
2. **Agent analyzes**: scope рефакторинга, затронутые файлы
3. **Agent creates**: `pyaqa/refactor/{name}.md` (опционально)
4. **Pre-check**: фиксирует baseline (все тесты проходят, coverage)
5. **Agent refactors**: пошаговые изменения
6. **Post-check**: все тесты проходят, coverage не ниже baseline
7. **Agent verifies**: линтеры, нет новых warnings
8. **User accepts**: опционально проверяет поведение
9. **Agent commits**: во все затронутые проекты
### Test Case Assignment Rules
- **TC-UNIT-NNN**: unit тесты (domain, use cases)
- **TC-API-NNN**: API endpoint тесты
- **TC-WEB-NNN**: Web route тесты (HTML responses, redirects)
- **TC-E2E-NNN**: End-to-end тесты (Playwright)
Нумерация внутри каждого уровня последовательная. Пропуски допустимы только при удалении устаревших тестов.
### Test Case Format
```markdown
### TC-UNIT-NNN: Test Name
- **Type:** Positive | Negative | Policy | Regression
- **Layer:** Unit | API | Web | E2E
- **File:** `path/to/test.py::TestClass::test_method`
- **Expected:** Что ожидается
- **Last Verified:** YYYY-MM-DD
```
### Red → Green → Refactor
- **RED**: Написать тест, убедиться что он падает
- **GREEN**: Написать минимальную реализацию, тест проходит
- **REFACTOR**: Улучшить код, тесты остаются зелеными
### Test Coverage Requirements
| Layer | Minimum Coverage | Notes |
|-------|-----------------|-------|
| Unit | 80% | Domain + Application |
| API | 70% | Endpoints + deps |
| Web | 60% | Routes + handlers |
| E2E | Cover all AC | Все acceptance criteria |
### Regression Test Rules
- **Bugfix**: ДОЛЖЕН включать regression test (unit минимум)
- **Refactor**: ВСЕ существующие тесты должны проходить ДО и ПОСЛЕ
- **Coverage**: Не должен упасть после багфикса или рефакторинга
## Anti-Patterns
- Do NOT add `@pytest.mark.asyncio` to `async def` tests (auto mode handles it)
- Do NOT use bare `Mock()` without `spec=` for interface mocks
- Do NOT delete tests to "fix" coverage — this is grounds for rollback
- Do NOT put fixtures in `__init__.py` — use `conftest.py`
- Do NOT write implementation before tests (no TDD bypass)
- Do NOT skip RED phase (tests must fail before implementation)
- Do NOT commit багфикс без regression test
- Do NOT commit рефакторинг с упавшим coverage
## Notes
- `mimesis` is installed but unused in any test
- E2E tests are excluded from default runs (`pyproject.toml` excludes `tests/e2e`)
- Pytest always runs with coverage (`--cov=app` in `addopts`)
- HTML coverage report generated at `htmlcov/index.html`

## Coverage Summary
| Component | Cases | Status |
|-----------|-------|--------|
| Post Entity | 8 | ✅ All core operations covered |
| Title VO | 5 | ✅ Validation rules fully covered |
| Content VO | 4 | ✅ Validation rules fully covered |
| Slug VO | 7 | ✅ Generation and validation covered |
| Domain Exceptions | 6 | ✅ All exception types covered |
## Gaps (Not Yet Covered)
- [ ] TC-UNIT-209: Post Entity — `updated_at` does not change when update values are identical
- [ ] TC-UNIT-210: Post Entity — attempt to publish already published post (idempotent behavior)
- [ ] TC-UNIT-317: Slug — collision handling (unique constraint) at domain level
- [ ] TC-UNIT-318: Content — exact boundary values (min length - 1, max length + 1)

# Test Model: RBAC & Access Control
Feature: Role-based access control and post visibility policies.
Defines who can create, read, update, delete, and view posts based on role
(GUEST, USER, ADMIN) and ownership.

## E2E Test Cases
### TC-E2E-101: Draft Visibility Policy Across Roles
- **Type:** Policy
- **Layer:** E2E
- **File:** `e2e/test_post_lifecycle.py::test_post_visibility_policies_across_users`
- **Preconditions:** Four browser contexts: user, user2, guest, admin
- **Steps:**
1. User creates a draft
2. User creates a published post
3. Verify home-page visibility for each role
4. Verify direct draft access by user2 returns 404
- **Expected:**
- User sees both posts
- User2 sees only published
- Guest sees only published
- Admin sees both
- User2 gets 404 on direct draft URL
- **Last Verified:** 2026-05-07
## Web Route Policy Reference
The following policies are implemented in `app/presentation/web/deps.py` and
`app/presentation/web/routes.py`. They are covered via E2E but lack dedicated
unit tests for the web layer.
| Function | Rule | Covered By |
|----------|------|------------|
| `can_create_post` | USER or ADMIN | E2E-001 |
| `can_edit_post` | ADMIN or own post author | Unit (use cases) |
| `can_delete_post` | ADMIN or own post author | Unit (use cases) |
| `can_see_draft` | ADMIN or own post author | E2E-101 |
| `_get_visible_posts` | GUEST: published only; USER: published + own drafts; ADMIN: all | E2E-101 |
### TC-E2E-102: Admin Can Edit Any Post
- **Type:** Positive
- **Layer:** E2E
- **File:** `e2e/test_post_ownership.py::test_admin_can_edit_any_post`
- **Preconditions:** Two browser contexts: user (creates post), admin (edits post)
- **Steps:**
1. User creates and publishes a post
2. Admin opens the post detail page
3. Admin clicks edit, changes title, and saves
4. Verify the post detail shows the updated title
- **Expected:** Admin sees edit button, successfully updates post, detail page reflects new title
- **Last Verified:** 2026-05-07
### TC-E2E-103: User Cannot Edit Other User's Post
- **Type:** Negative
- **Layer:** E2E
- **File:** `e2e/test_post_ownership.py::test_user_cannot_edit_other_users_post`
- **Preconditions:** Two browser contexts: user (creates post), user2 (attempts edit)
- **Steps:**
1. User creates and publishes a post
2. User2 opens the post detail page
3. Verify edit button is not visible
4. User2 attempts direct access to `/web/posts/{slug}/edit`
- **Expected:** Edit button is hidden; direct access returns 403 error page
- **Last Verified:** 2026-05-07
## Coverage Summary
| Aspect | Coverage | Notes |
|--------|----------|-------|
| Role definitions | Unit | Enum values and permission mapping fully tested |
| Permission checks | Unit | `has_permission` and `get_effective_role` fully tested |
| Web-level enforcement | E2E | Visibility and ownership rules tested via browser |
| API-level enforcement | — | No API tests exist after refactor |
## Gaps (Not Yet Covered)
- [x] TC-UNIT-113: Web deps — `can_create_post` for each role
- [x] TC-UNIT-114: Web deps — `can_edit_post` for owner vs non-owner
- [x] TC-UNIT-115: Web deps — `can_delete_post` for owner vs non-owner
- [x] TC-UNIT-116: Web deps — `can_see_draft` for each role combination
- [ ] TC-API-101: API POST create — unauthorized (no token)
- [ ] TC-API-102: API POST create — forbidden (guest token)
- [ ] TC-API-103: API GET unpublished post — forbidden (other user)
- [ ] TC-E2E-104: Admin can delete any post via web UI
- [ ] TC-E2E-105: User cannot delete other user's post via web UI

# Test Model: Blog
Global test coverage map for the blog application. Use this file to assess
which features are covered, where gaps exist, and what to prioritize when
adding new tests.
## Coverage Matrix
| Feature | Unit | Integration | API | E2E | Priority | Status |
|---------|:----:|:-----------:|:---:|:---:|:--------:|:------:|
| Post Lifecycle (CRUD, Publish) | 85% | — | — | 70% | P0 | ✅ Active |
| RBAC & Access Control | 100% | — | — | 60% | P0 | ✅ Active |
| Domain Value Objects | 100% | — | — | — | P0 | ✅ Stable |

| Transaction Manager | 60% | — | — | — | P2 | ⚠️ Partial |
| Web UI Error Handling | — | — | — | 50% | P1 | ⚠️ Partial |

Legend: ✅ Covered / ⚠️ Partial / ❌ Missing / — Not Applicable
## Feature Files
| Feature | Model File |
|---------|------------|
| Post Lifecycle | [FEATURE_POST_LIFECYCLE.md](FEATURE_POST_LIFECYCLE.md) |
| RBAC & Access Control | [FEATURE_RBAC.md](FEATURE_RBAC.md) |

| Infrastructure & Bootstrap | [FEATURE_INFRASTRUCTURE.md](FEATURE_INFRASTRUCTURE.md) |
## Test Naming Convention
- **TC-UNIT-NNN**: Unit test case
- **TC-E2E-NNN**: End-to-end test case
- **TC-INT-NNN**: Integration test case
- **TC-API-NNN**: API test case
## How to Update This Model
1. When adding a new test, assign the next available TC-ID in the relevant feature file.
2. Update the Coverage Matrix above if the new test closes a gap or changes coverage percentage.
3. Update the `Last Verified` field in the feature file after running the test successfully.
4. When a test is deleted or renamed, update the corresponding TC entry and mark it as **Deprecated**.
## Risk Areas
1. **No Integration Tests**: SQLAlchemy repository has no integration tests against a real database.
2. **Deleted API Tests**: API endpoint tests were removed in a previous refactor and need restoration.
3. **Web UI Error Handling**: Only covered indirectly via E2E; no dedicated error-scenario E2E tests.
4. **Pagination Edge Cases**: Page boundaries, empty pages, and large offsets are not explicitly tested.
5. **Edit/Delete Web Flows**: No E2E coverage for editing or deleting posts through the web UI.
