# Matrix room message handling tests - converted from unittest.TestCase to standalone pytest functions
#
# Conversion rationale:
# - Improved readability with native assert statements instead of self.assertEqual()
# - Better integration with pytest fixtures for test setup and teardown
# - Simplified async test execution without explicit asyncio.run() calls
# - Enhanced test isolation and maintainability
# - Alignment with modern Python testing practices
