Reorganized OAuth Tests -**Directory**: `tests/server/oauth/` - -Moved all OAuth-related tests to dedicated subdirectory: -- Created `test_oauth_core.py` - consolidated basic OAuth connectivity tests -- Moved 7 OAuth test files to `oauth/` subdirectory -- Fixed relative imports (`..conftest` → `...conftest`) - -**Files**: -- `test_oauth_core.py` - Basic OAuth connectivity & JWT operations (8 tests) -- `test_scope_authorization.py` - Scope filtering & enforcement (16 tests) -- `test_introspection_authorization.py` - Token introspection auth (5 tests) -- `test_dcr_token_type.py` - Dynamic client registration (3 tests) -- `test_oauth_notes_permissions.py` - Notes app permissions (4 tests) -- `test_oauth_deck_permissions.py` - Deck app permissions (4 tests) -- `test_oauth_file_permissions.py` - Files app permissions (4 tests) - -**Total**: ~48 OAuth tests - -#### 4. Created Smoke Test Suite -**Directory**: `tests/smoke/` - -Added critical path validation tests (~30-60 seconds): -- `test_smoke.py` (5 tests) - Essential functionality validation - - MCP connectivity - - Notes CRUD - - Calendar basic operations - - WebDAV basic operations - - OAuth connectivity - -#### 5. Updated Documentation -**File**: `CLAUDE.md` - -Added comprehensive test execution guide: -```bash -# Fast feedback (unit tests) - ~5 seconds -uv run pytest tests/unit/ -v - -# Smoke tests - ~30-60 seconds -uv run pytest -m smoke -v - -# Integration without OAuth - ~2-3 minutes -uv run pytest -m "integration and not oauth" -v - -# Full suite - ~4-5 minutes -uv run pytest - -# OAuth only - ~3 minutes -uv run pytest -m oauth -v -``` - -Added test structure diagram and marker documentation. - -### Test Suite Metrics - -**Before Reorganization**: -- ~235 tests, all integration -- No fast feedback loop -- All tests take ~5-7 minutes -- OAuth tests scattered across 9 files - -**After Reorganization**: -- 234 tests total (11 unit + 5 smoke + ~218 integration) -- **Fast feedback**: unit tests in ~5 seconds -- **Quick validation**: smoke tests in ~30-60 seconds -- **Focused testing**: integration without OAuth in ~2-3 minutes -- **Full suite**: ~4-5 minutes -- OAuth tests consolidated in dedicated directory - -### Feedback Time Improvements - -| Test Type | Count | Time | Use Case | -|-----------|-------|------|----------| -| Unit only | 11 | ~5s | Logic changes, model updates | -| Smoke only | 5 | ~30-60s | Critical path validation | -| Integration (no OAuth) | ~172 | ~2-3min | API/MCP changes | -| OAuth only | 48 | ~3min | OAuth feature work | -| **Full suite** | **234** | **~4-5min** | **Pre-commit validation** | - -### Key Benefits - -1. **Fast Development Feedback** - - Unit tests run in 5 seconds vs. 5+ minutes - - Immediate validation for logic changes - -2. **Efficient CI/CD** - - Can run unit tests on every commit - - Run smoke tests for pull requests - - Full suite for merge to main - -3. **Better Organization** - - OAuth tests grouped together - - Clear test purpose from directory structure - - Easier to navigate and maintain - -4. **Selective Execution** - - Skip slow OAuth tests during development - - Run only relevant test layer - - Faster iteration cycles - -### Migration Notes - -- **No breaking changes** to existing tests -- All tests continue to work as before -- Legacy commands still supported (`-m integration`, etc.) -- OAuth tests moved to subdirectory, imports updated -- Removed duplicate tests consolidated into `test_oauth_core.py` - -### Next Steps (Optional Future Work) - -1. **Further Consolidation**: Merge remaining OAuth permission tests -2. **More Unit Tests**: Add unit tests for client initialization, search logic -3. **Client/Server Deduplication**: Reduce overlap between client and server tests -4. **CI Pipeline**: Configure GitHub Actions to run test layers separately -5. **Performance**: Optimize fixtures to reduce setup time - -### Commands Reference - -```bash -# Development workflow -uv run pytest tests/unit/ -v # Check logic changes -uv run pytest -m smoke -v # Quick validation -uv run pytest -m "integration and not oauth" -v # Full validation without slow tests - -# Before committing -uv run pytest # Run everything - -# Working on OAuth features -uv run pytest tests/server/oauth/ -v # OAuth tests only -uv run pytest -m oauth --browser firefox --headed -v # Debug OAuth with visible browser -```
