"""
Shared test fixtures for the kleinanzeigen-bot test suite.

This module contains fixtures that are used across multiple test files.
Test-specific fixtures should be defined in individual test files or local conftest.py files.

Fixture Organization:
- Core fixtures: Basic test infrastructure (test_data_dir, test_bot_config, test_bot)
- Mock fixtures: Mock objects for external dependencies (browser_mock)
- Utility fixtures: Helper fixtures for common test scenarios (log_file_path)
- Smoke test fixtures: Special fixtures for smoke tests (smoke_bot, DummyBrowser, etc.)
- Test data fixtures: Shared test data (description_test_cases)
