## Test Quality Standards



All tests follow GUIDE_TEST.md standards:



✅ **Descriptive naming** - `test_<action>_<expected_outcome>`  

✅ **Proper markers** - Library and category markers  

✅ **Test isolation** - Independent tests with fixtures  

✅ **Error testing** - Both success and failure paths  

✅ **Edge cases** - Boundary conditions and special values  

✅ **Documentation** - Docstrings explaining test purpose  

✅ **No forbidden patterns** - No skipping, no rigged tests  

✅ **Root cause fixing** - Tests verify actual behavior
