Implemented full test coverage for core bot components: Test Coverage: - MentionDetector: 98% (28 tests) - mention detection, nickname handling, content extraction - Logger: 98% (15 tests) - file logging, log levels, unicode support - ConversationMemory: 91% (25 tests) - history management, time filtering, JSON persistence - PerplexityProvider: 100% (22 tests) - API calls, error handling, statistics - Config: 100% (26 tests) - env loading, validation, JSON config Infrastructure: - Added pytest, pytest-asyncio, pytest-mock, pytest-cov to requirements.txt - Created pytest.ini with coverage configuration - Created .coveragerc to exclude non-production files - Added conftest.py with shared fixtures and test isolation Test Features: - 116 total tests, all passing - Isolated test environment (clean env vars, logging handlers) - Async testing support for PerplexityProvider - Mocked HTTP requests to avoid real API calls - Comprehensive edge case coverage - Unicode/German character support testing Total: 97% code coverage across 273 statements
