Run a specific project unit test (DamerauLevenshteinAlgorithm) with Junit including .java files

I'm have never done nay java or used java tools, I’m using linux. I am trying to find how i could run these tests form someone’s implementation of the Damerau-Levenshtein algorithm.

I have found this How to run JUnit test cases from the command line of course but I could not manage to deal with it.

It is really not important the way to run these unit tests (CLI or whatever), but how could I run these unit tests ?

How to run Junit test on command line with .java files ?
