import { Selector, ClientFunction } from 'testcafe';

fixture `Full Screen Switching`
    .page `http://example.com`;

const toggleFullScreen = ClientFunction(() => {
    const doc = document.documentElement;
    if (doc.requestFullscreen) {
        doc.requestFullscreen();
    } else if (doc.mozRequestFullScreen) {
        doc.mozRequestFullScreen();
    } else if (doc.webkitRequestFullscreen) {
        doc.webkitRequestFullscreen();
    } else if (doc.msRequestFullscreen) {
        doc.msRequestFullscreen();
    }
});

test('Switch to full screen mode', async t => {
    // 点击触发全屏切换
    await toggleFullScreen();

    // 在全屏模式下执行其他测试步骤
    // ...

    // 切换回正常模式
    await toggleFullScreen();
});
