I have reviewed the documentation, but still haven't found how to obtain the re rendered elements, eg:
const ref = createRef<TabInstance>(); const { rerender,getByRole } = render(<TabComponent headerRef={ref} />); const input = getByRole('textbox') expect(ref.current).toBeDefined(); rerender(<TabComponent headerRef={ref} value="3" />) // May I ask how to obtain the rendered `const input = getByRole('textbox')` element
I'm not sure how I should obtain it, I haven't found any valid information on the document

Hi @19Qingfeng.
I'm not sure I'm following the purpose of this test.
Using ref inside a test isn't a best practice since when we're testing we should act as if we're the user using our app.
If you want to test this component, I'd assert on what the user is actually seeing, if the value 3 is presented, I'd assert that.
