Test Independence
- Each test must run in isolation - no shared state between tests
- Use fixtures for setup/teardown, never class-level mutable state
- Tests should pass regardless of execution order
Naming Conventions
- Files:
test_*.pyor*_test.py - Functions:
test_<description>() - Classes:
Test<ClassName> - Fixtures: descriptive
