Code Review

This pull request adds a comprehensive suite of unit tests for the FilterBar component, its related FilterBarMobileSwitch component, and the useFilterBarState hook. The tests are well-structured and cover a wide range of scenarios, including rendering logic, user interactions, responsive behavior, accessibility, and edge cases. The use of @testing-library is excellent.

I've identified a critical issue that would prevent the tests from running due to a reference error in a mock. I've also provided several suggestions to improve test maintainability, clarity, and completeness. These include using more idiomatic matchers, improving type safety for mocks, and enhancing test scenarios for better coverage and readability. Overall, this is a great addition, and with these changes, the test suite will be even more robust.
