Target 80%+ code coverage. ## Acceptance Criteria - [x] `tests/test_connection.py` created - [x] Test successful connection to server - [x] Test connection timeout handling - [x] Test disconnect clears state properly - [x] Test require_connection when not connected raises error - [x] Test require_connection when connected returns client - [x] Test statistics tracking (increments correctly) - [x] Test multiple connect/disconnect cycles - [x] Test connection state persistence across operations - [x] Test environment variable configuration (timeouts) - [x] Code coverage ≥ 80% for connection.py (98% achieved) ## Technical Notes **Test categories:** 1. Happy path - successful connection and operations 2. Error paths - timeouts, failures, invalid states 3. State management - verify state transitions 4. Statistics - verify counters update correctly 5. Configuration - environment variables work **Key tests:** ```python async def test_connect_success(mock_mcp_server): """Test successful connection to server""" async def test_connect_timeout(): """Test connection timeout handling""" async def test_disconnect_clears_state(): """Test disconnect clears connection state""" async def test_require_connection_when_not_connected(): """Test error when no connection exists""" ``` ## AI Directives **IMPORTANT**: As you work through this story, please mark checklist items as complete `[x]` as you finish them. This ensures that if we need to pause and resume work, we have a clear record of progress. Update the `status` field in the frontmatter when moving between stages (in-progress, ready-for-review, done, blocked). Achieve 80%+ coverage. Test both happy paths and failure scenarios.
