No query params when rendering routed component in unit test

I am attempting to test a specific route within my React component that relies on the window having visible search parameters. For example:

const MyComponent = () => {
    if (window.location.search) {
        return <h1 data-testid="query">Has search params</h1>
    }

    return <h1 data-testid="no-query">No search params</h1>
}

My test for such an occurance is as such:

it('should go down query route', () => {
    const initialState = configState(); // Set up Redux store

    const path = '/my-comp';
    const search = '?some=search';

    const history = createMemoryHistory({
        initialEntries: [{
           pathname: path, 
           search: search
        }]
    });
    history.push(redirectFrom);

    const mockStore = configureStore();
    
    const {queryByTestId} = render (
        <Provider store={mockStore(state)}>
           <Router history={history}>
              <MyComponent />
           </Router>
        </Provider>
    );
    
    expect(queryByTestId('query')).not.toBeNull();
    expect(queryByTestId('query').textContent).toBe('Has search params');

    expect(queryByTestId('no-query')).toBeNull();
});

I found that the tests weren't passing, so I added a console.log(window.location) at the start of my component to see the path, search etc that the component was being rendered with and I found that all of the expected properties were missing:

{ 
    href: 'http://localhost/',
    origin: 'http://localhost',
    host: 'localhost',
    hostname: 'localhost',
    port: '',
    pathname: '/',
    search: '',
    hash: '' 
}

A bit of background info:

• The App is built with Redux
• This component is rendered as part of a <Router> within an App as you might expect:

const App = () => {
    return (
        <Provider>
           <ConnectedRouter>
              <Route path="my-comp" component={MyComponent} />
              // More routes here
           </ConnectedRouter>
        </Provider>
    )
}
