Hi! I want to add support of /shorts/ Youtube link. My modification of the YoutubeOnebox class works, but it is required that I add a test in youtube_onebox.rb and my test doesn’t work. Similar to the “can parse youtube embed results” test, I added this code: it "can parse youtube shorts results" do preview = expect(Onebox.preview('https://www.youtube.com/watch?v=wi2jAtpBl0Y').placeholder_html) preview.to match(/From which sound/) preview.to match(/hqdefault/) end I also added this at the beginning of the file, in before do: stub_request(:get, "https://www.youtube.com/shorts/wi2jAtpBl0Y").to_return(status: 200, body: onebox_response("youtube-shorts")) I have never done unit testing before, so I don’t really understand of all of this work. My test failure: Failures: 1) Onebox::Engine::YoutubeOnebox can parse youtube shorts results Failure/Error: http.request(request) do |response| if cookie = response.get_fields('set-cookie') # HACK: If this breaks again in the future, use HTTP::CookieJar from gem 'http-cookie' # See test: it "does not send cookies to the wrong domain" redir_header = { 'Cookie' => cookie.join('; ') } end redir_header = nil unless redir_header.is_a?

Also, what do these parts do in before do? onebox_response("youtube-embed") The “youtube-embed” string doesn’t seem to be used anywhere in Discourse’s code except here. What is its purpose? Why are there twice /embed/ links and why onebox_response has a different string parameter? stub_request(:get, "https://www.youtube.com/embed/21Lk4YiASMo") .to_return(status: 200, body: onebox_response("youtube")) stub_request(:get, "https://www.youtube.com/embed/KCyIfcevExE") .to_return(status: 200, body: onebox_response("youtube-embed"))

I fixed it in a new PR that has correct attribution to you as a Co-Author: https://github.com/discourse/discourse/pull/19335 [תמונה] Coin-coin le Canapin: Why are there twice /embed/ links and why onebox_response has a different string parameter? To make our test suite not depend on a working internet connection (and working Youtube), we stub all internet requests by making those call return with a cached response. the onebox_response function will call the file with a matching name as the parameter passed from the folder discourse/spec/fixtures/onebox at main · discourse/discourse · GitHub. I added a new .response file for a shorts so we have a good test, but that was all that was necessary for this. Thanks for the PR!

[תמונה] Coin-coin le Canapin: Do you have any clue why it fails? I’m not very good at this either, but you need to make that stub have exacctly the same stuff that youtube would return. So it needs to have some subset of what wget https://www.youtube.com/embed/wi2jAtpBl0Y returns. That’s what your spec needs as its input. wc wi2jAtpBl0Y 6 251 65245 wi2jAtpBl0Y That’s a lot of text to make sense of and stick in your stub.

Sure, here it is! https://github.com/discourse/discourse/pull/19305

Video unavailable The uploader has not made this video available in your country Besides this, it should work :smile:

It works for me. Quick question. Here’s the email notification I got: [image] The URL here is /embed/ and not /shorts/, but I suppose this is normal?

Can you open a draft PR with your current changes? That will be easier to follow along and help with. With the current information it looks like you need to create the stub files and stub and the outgoing requests.
