Set up testing infrastructure with pytest-django

[robert197]

Description

Configure a robust testing setup that Claude Code can use to verify implementations.

Requirements

• pytest-django as the test runner
• factory_boy for test data factories
• pytest-cov for coverage reporting
• pytest-xdist for parallel test execution
• Test directory structure mirroring app structure
• Fixtures for common test scenarios (owner, apartment, inspection)
• Base test classes for common patterns

Test Structure

tests/
├── conftest.py          # Shared fixtures
├── factories.py         # factory_boy factories
├── accounts/
│   ├── test_models.py
│   └── test_views.py
├── apartments/
├── inspections/
└── reports/

Key Factories

• OwnerFactory - Creates owner with auth user
• ApartmentFactory - Creates apartment with owner
• InspectionFactory - Creates inspection with items
• InspectorFactory - Creates inspector user

Acceptance Criteria

• pytest runs and passes with zero tests (setup works)
• Factories generate valid test data
• Coverage report generated on test run
• make test shortcut works

Constraint: Tests run inside Docker (see #3). make test wraps docker compose exec web pytest. CI uses the same Docker image. No local pytest install needed.

Dependencies: Blocked by #1, #3. See build order in #44.
