Backend tests:
- Unit tests for docker_build service (successful/failed builds, context, paths)
- Unit tests for readiness_probe service (success, timeout, retries, edge cases)
- Integration tests for config_folders API (CRUD + project overrides)
- Integration tests for tool_types API with new fields
- Integration tests for tool_configs API with new fields
Frontend tests:
- ToolWorkshopPage component tests (all 3 tabs, create/edit/delete)
- API client tests for tool_types and config_folders
Fixes:
- Add field_validator import to tool_configs.py
- Add JSON import to tool_config model
- Update frontend test button names to match UI (Create Tool Type, Add Config, Create Folder)
Quality gates: backend unit tests passing (23/23)
