What makes a paper unique to be published if I am working in my master on some original case just to verify the code I am developing ?

At the end, The master itself is writing some original code, nothing new, and the paper, of course, will be also on some original case. Isn't that the main purpose of the master ? to learn how to conduct a research !!

So how can I handle that "unique" thing in publishing a good paper ? Isn't it a requirement, by definition ?

To understand what a paper must have to be published the journals have the indications for the authors in their sites. I suggest to have a careful look.
The appropriate journals are chosen among those of the papers you referenced in your study.
In general, I can say that the paper have to be original, well written and the goal of the research must be clearly stated. It is relevant the methodology and the validation.
