Update test case. Replace enzyme test code with @testing-library/react.

Update test cases in `tests/index.spec.tsx` to use `@testing-library/react` instead of `enzyme`.

* Replace `enzyme` imports with `@testing-library/react` imports.
* Update test cases to use `render`, `fireEvent`, and other utilities from `@testing-library/react`.
* Remove `mount` and `ReactWrapper` imports.
* Change code `props.style` with `toHaveStyle({ key: value })` style.
* Change `style.display` check to be `toHaveStyle("display: block")` or `display: none`.
