[FEATURE] Add tests for Drifty

[SaptarshiSarkar12]

Is your feature request related to a problem? Please describe.

It is a tedious task to check if Drifty can still download all the supported types of files like YouTube, and Instagram videos and Spotify songs along with general files like https://download.oracle.com/java/22/latest/jdk-22_linux-x64_bin.deb.

Describe the solution you'd like.

Adding multiple separate JUnit tests (I suppose this would suffice; If you think integration testing would be better in some scenario, please let me know) for each download category, batch processing, etc. would be better. Moreover, these tests can then be run on schedule via GitHub Actions allowing automated testing.

If anyone wants to work on this issue, please comment below. I would assign this task to you.

hey im currently working on this issue. Is anybody already working on that?

[SaptarshiSarkar12]

@JjJjJose Hi José 👋! No one is currently working on this issue. Feel free to work on this issue. I am assigning this task to you. Thank you for your interest 😁.

[JjJjJose]

@SaptarshiSarkar12 hey! Right now im working on the unit tests and the youtube link is done i think, heres a example

it was really a pain in the head ahahaha i will do eventually the instagram and spotify links and make a note for future contributors for the file

[SaptarshiSarkar12]

@JjJjJose Great 😃. Are you testing the link type? Are you using the LinkType class? The outcome looks good and informative which is useful for debugging purposes.

[JjJjJose]

i was using indirectly, actually i was using DownloadConfiguration class. i will use the LinkType class for tests!

and thank you !!! :D Junit is really simple to understand but never got my hands on big projects like that

[SaptarshiSarkar12]

Yeah, you can use Link type class for that purpose.

Junit is really simple to understand

That's true 😁

...but never got my hands on big projects like that

I hope you would enjoy working in this project on this issue gaining enough experience to work on more such big projects 😃.

[JjJjJose]

really appreciate it 😄

if you have any extra info about the link Type class feel free to comment!

[SaptarshiSarkar12]

@JjJjJose The class is self explanatory, I suppose. Nothing more to tell 😄. If you don't understand any usage/method, you can comment.

[JjJjJose]

when i try to implement the class the test keeps on a infinite loop, any idea how to fix it?

[SaptarshiSarkar12]

Show me the code

hello, sorry for the delay i was busy

@JjJjJose it's fine 😃.

From your code, it is clear that you're mixing things up. You are testing DownloadConfiguration class and the download process in the same test class. I suggest you to break down the test classes with the minimum work. For example, you can create test classes in Core module to test the Environment class, LinkType class, UnitConverter class, DownloadConfiguration class, etc. Then, creating the test classes in CLI module, for any specific class like you can check if theMessageBroker passed to CLI isinstanceOf CLI.MessageBroker.

You can check this branch to get more idea about the point I'm emphasising. The branch hasn't been updated for a long time and is just a trial of how tests can be integrated in this project. I hope it helps you in understanding the procedure I mentioned. Please let me know if you have understood this or have any question.

[JjJjJose]

oh that helps a lot thanks man! sorry for the trouble ahahaha, i will be looking in the next few days, if i got any questions i post here!

[SaptarshiSarkar12]
