有没有办法在testcafe中断言带有部分文件名的下载文件？

import { Selector, ClientFunction } from 'testcafe';

fixture `File Download Test`
    .page `https://example.com`;

test('Download File with Partial Filename Assertion', async t => {
    const downloadLink = Selector('a').withText('Download File');
    const getFileUrl = ClientFunction(() => downloadLink.getAttribute('href'));

    await t
        .click(downloadLink)
        .expect(getFileUrl()).ok();

    const fileName = await getFileUrl().split('/').pop();
    await t.expect(fileName).contains('partial_filename');
});
