+ * This file contains unit tests for the CheckInWrapper component.
+ *
+ * The tests cover:
+ * - Rendering and behavior of the modal component.
+ * - Functionality of the button to open and close the modal.
+ * - Integration with mocked GraphQL queries for testing Apollo Client.
+ *
+ * Purpose:
+ * These tests ensure that the CheckInWrapper component behaves as expected
+ * when opening and closing modals, and correctly integrates with its dependencies.
