Add comprehensive tests to achieve 82% coverage
Added two new test files to improve test coverage from 71% to 82%: 1. test_websocket_coverage.py (12 tests): - Comprehensive testing of start_terminal handler - Error handling tests (container not found, exec errors, socket errors) - Unicode and latin-1 decoding tests - Default terminal size verification - Socket wrapper and direct socket fallback tests 2. test_edge_cases.py (11 tests): - Edge cases for all REST API endpoints - Invalid token formats - Docker error scenarios - Missing/empty request fields - Container operation failures Test Results: - Total: 77 tests passed, 2 skipped - Coverage: 82% (373 statements, 64 missing) - Exceeds 80% target coverage - All critical code paths tested https://claude.ai/code/session_01B9dpKXH8wbD7MPtPBDHrjq
