Add if-else statement to run tests against real website on schedule

[XiangRongLin]

• I carefully read the contribution guidelines and agree to them.
• I have tested the API against NewPipe.
• I agree to create a pull request for NewPipe as soon as possible to make it compatible with the changed API.

I realized that running the tests against real website is basically just copying the ci.yml and changing one value.
Which can also be done with an if condition.

Because github actions if has no else, the shell script ones are used

I like this! Is it really that simple? :-D

[XiangRongLin]

Should be.
I forgot to link this one: XiangRongLin#4
where the action does: https://github.com/XiangRongLin/NewPipeExtractor/pull/4/checks#step:2:8

@Stypox let the action on my repo run for a night and tomorrow we can see if it echoed the correct thing

[XiangRongLin]

Seeing how there already are new failing tests not even an hour after merging #512, we probably need a way to mark tests to be skipped in the ci pipeline if they are not run with mocks.

@XiangRongLin good idea

It works

Great! @TobiGr

[TobiGr]

Can be merged once review is implemented

[TobiGr]

Ah wait. wasn't there a complaint regarding automated testing when they took down youtube-dl?

@TheAssassin This introduces sheduled tests against the real websites, whereas some predefined JSONs are tested against PRs. Is that ok?

[XiangRongLin]

@TobiGr I think part of it was that there we unit tests, that were downloading copyrighted stuff

see last paragraph of this section https://github.blog/2020-11-16-standing-up-for-developers-youtube-dl-is-back/#youtube-dl

So we would need to check all tests once and see if there are any such tests and replace them
