# Current Issues:
|
|
# - test_tailwind_classes_creation: assertion failed on responsive classes
|
|
# - test_class_builder: assertion failed on responsive classes
|
|
# - test_validate_class: validation logic issues

## Conclusion
|
|
|
|
This remediation plan provides a systematic approach to achieving 90%+ test coverage across the `leptos-shadcn-ui` repository. By focusing on critical infrastructure fixes, zero coverage areas, and component implementation coverage, we can significantly improve code quality and maintainability.
|
|
|
|
The 6-week timeline provides a realistic path to achieving comprehensive coverage while maintaining code quality and development velocity. Regular monitoring and quality assurance ensure that coverage improvements translate to actual quality improvements.
