"""
Integration tests for the ParameterEditorTable class.

This file contains integration tests that verify component interactions and workflows
in the parameter editor table. These tests validate how multiple components work together,
testing through both public and internal APIs with appropriate mocking of external dependencies.

While these tests are behavior-focused and include Given-When-Then structure, they are
integration tests rather than pure BDD tests, as they:
- Test internal methods and private APIs (prefixed with _)
- Mock internal components (BaseWindow, tkinter widgets)
- Verify implementation details and method calls

For unit tests of individual methods and implementation details, see unit_frontend_tkinter_parameter_editor_table.py.
