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? Hash

Do you have any clue why it fails?
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"))
