React testing, I use act, writes that I don't use it, how to fix it?

Question

Software testing

To render the component I use this entry:

act(() => 
        render(
            <Router history={history}>
                <Route path="/v/:id">
                    <SingleVideo/>
                </Route>
            </Router>
        )
    )

Gives an error message:

When testing, code that causes React state updates should be wrapped into act(...):
      
      act(() => {
        /* fire events that update state */
      });
      /* assert on the output */

Probably a syntax error, tell me how to fix this code?
