+/**
+ * `useBaseSearch` composable function mock.
+ *
+ * If default values are sufficient for tests,
+ * you only need call `jest.mock('<useBaseSearch file path>')`
+ * at the top of a test file.
+ *
+ * If you need to override some default values from some tests,
+ * you can import a helper function `useBaseSearch` that accepts
+ * an object with values to be overriden and use it together
+ * with  `mockImplementation` as follows:
+ *
+ * ```
+ * // eslint-disable-next-line import/named
+ * import useBaseSearch, { useBaseSearch } from '<useBaseSearch file path>';
+ *
+ * jest.mock('<useBaseSearch file path>')
+ *
+ * it('test', () => {
+ *   useBaseSearch.mockImplementation(
+ *     () => useBaseSearch({ classes: [{ id: 'class-1' }] })
+ *   );
+ * })
+ * ```
+ *
+ * You can reset your mock implementation back to default values
+ * for other tests by calling the following in `beforeEach`:
+ *
+ * ```
+ * useBaseSearch.mockImplementation(() => useBaseSearch())
+ * ```
