How to mock a binary file?

[Mese1953]

I need to mock a fetch call, which returns a pdf.

Not sure who to do that. I've already tried some stuff like:

fetchMocker.mockResponseOnce(await readFile(path));

I haven't tried this yet, but I think it should be something like:

import { readFile } from 'node:fs/promises';

const buffer = await readFile("path/to/file");

fetchMocker. mockResponseOnce(new Response(new Blob([buffer])));
