From 90a70a85eb6bb476197786c170dfa688cc40464d Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 3 Jan 2026 10:04:38 +0000 Subject: [PATCH] Achieve 100% test coverage with comprehensive improvements MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Enhanced test suite from 97% to 100% coverage with 173 passing tests. ## New Features ### 1. Error Handling Tests (3 tests) - test_add_message_handles_read_error_gracefully - test_add_message_handles_write_error_gracefully - test_clear_user_history_handles_permission_error - test_logger_reuses_existing_handlers Coverage: memory.py 91% β†’ 100%, utils.py 98% β†’ 100% ### 2. Integration Tests (9 tests) - test_integration.py - test_mention_to_response_workflow: Full message flow - test_conversation_context_preserved: Multi-turn conversations - test_config_to_components_integration: Component initialization - test_error_recovery_workflow: Graceful error handling - test_mention_detection_integration_with_nicknames - test_memory_limit_enforcement_in_workflow - test_ambiguous_greeting_workflow - test_logger_integration_with_memory - test_logger_integration_with_ai_provider - test_config_validation_workflow ### 3. Parameterized Tests (45 tests) - 18 mention detection test cases - 17 greeting detection test cases - 8 content extraction test cases - Covers edge cases, unicode, nicknames, false positives ### 4. GitHub Actions CI Workflow - Multi-Python version testing (3.9, 3.10, 3.11, 3.12) - Automated coverage reporting - Code quality checks (Black, isort, flake8) - Codecov integration - Coverage badge generation ## Test Statistics - Tests: 116 β†’ 173 (+49% increase) - Coverage: 97% β†’ 100% (+3pp) - Execution time: ~1.1 seconds - All components: 100% coverage ## Files Modified - tests/test_utils.py: Added parameterized tests and error handling -
