act is imported from @testing-library/react but never used. This will fail lint/tsc if unused imports are checked during CI; remove it or use it to wrap updates that rely on effects/state flushes.

container is destructured from render(...) here but never used. This is an unused variable that can cause lint/TypeScript failures; remove the destructuring (or assert against container if needed).

This test doesn't actually validate that onApplyFilters is invoked (it only asserts that no “Apply” button is present). This contradicts the PR description and leaves the callback behavior untested; either (a) trigger whatever UI action is supposed to call onApplyFilters and assert it was called, or (b) remove/rename this test and update the PR description accordingly.
Add tests for gadgetFilters component
ref #20
This PR introduces a new test file for the
GadgetFilterscomponent located insrc/gadgets/gadgetFilters.tsx.The tests validate that the component renders correctly, updates filter state when inputs change, and properly invokes the
onApplyFilterscallback when filters are applied.How to use
Reviewers can validate the changes by running the test suite locally.
Steps:
Testing done
Commands executed:
npm install
npm test
Result:
All tests passed successfully and the new test file
src/gadgets/gadgetFilters.test.tsxexecuted without errors.
