The following example demonstrates how to use the t.resizeWindow action.

import { Selector } from 'testcafe';

const menu = Selector('#side-menu');

fixture `My fixture`
    .page `http://www.example.com/`;

test('Side menu disappears on small screens', async t => {
    await t
        .resizeWindow(200, 100)

You can also resize window to fit a specified type of device with t.resizeWindowToFitDevice method and maximize window with t.maximizeWindow.
