[FIXED] JUnit test on JAVA failed

Issue

I'm new here, so sorry in advance for stupid question.

I have some problems with my JUnit test: For some reasons it shows me mistake in index.

I attached the link to my repository with test and screens.

Thank you! ERROR:

org.opentest4j.AssertionFailedError: array contents differ at index [0], 
expected: <Poster(id=3, pictureId=33, filmName=Space, filmGenre=Lamusic)> 
but was: <Poster(id=2, pictureId=22, filmName=Moon, filmGenre=Lamedy)>

Solution

In your second test getLastPosters2() (which is not working) you assert a different ordering, than your first test getLastPosters().

Poster[] expected = new Poster[]{thirdFilm,secondFilm};

This is the reverse order, which you are adding to your PosterManager.

Change the order to the following and the test is working:

Poster[] expected = new Poster[]{secondFilm,thirdFilm};

At your first test getLastPosters() you assert in the same ordering, as you are adding them to the PosterManager.

However, either your second test is asserting the wrong order and fails, or your implementation is wrong, and your first test is "false-positive".
