There's not a fancy way check if the download has finished, TestCafe is somewhat limited in its ability to control the download ability in the browser.

import fs from 'fs';

const fileName = 'junk.txt';
const downloadLocation = 'C:\Wherever\Downloads\';
const fileDLUrlBase = 'https://example.com/downloads/';
fixture('download test fixture');
test('download test', async t => {
  await t.navigateTo(fileDLUrlBase + fileName);
  await t.wait(30000);
  // Wait 30 seconds
  await t.expect(fs.fileExistsSync(downloadLocation + fileName));
});

You could convert that to a loop that checks, say, every 5 seconds for 60 seconds, if you wanted.
