Add tests for YoutubeDashManifestCreator and ManifestCreatorCache
The test added in YoutubeDashManifestCreator uses a video of the Creative Commons channel, licenced under the Creative Commons Attribution licence (reuse allowed). Also remove public keywords of tests in UtilsTest, as suggested by SonarLint, because they are not needed with Junit 5.

/**
|

* Test for {@link YoutubeDashManifestCreator}.
|
||||
*
|
||||
* <p>
|
||||
* We cannot test the generation of DASH manifests for ended livestreams because these videos will
|
||||
* be re-encoded as normal videos later, so we can't use a specific video.
|
||||
* </p>
|
||||
*
|
||||
* <p>
|
||||
* The generation of DASH manifests for OTF streams, which can be tested, uses a video licenced
|
||||
* under the Creative Commons Attribution licence (reuse allowed):
|
||||
* {@code https://www.youtube.com/watch?v=DJ8GQUNUXGM}
|
||||
* </p>
|
||||
*
|
||||
* <p>
|
||||
* We couldn't use mocks for these tests because the streaming URLs needs to fetched and the IP
|
||||
* address used to get these URLs is required (used as a param in the URLs; without it, video
|
||||
* servers return 403/Forbidden HTTP response code).
|
||||
* </p>
|
||||
*
|
||||
* <p>
|
||||
* So the real downloader will be used everytime on this test class.

* </p>
