LayoutFunctions/ClassroomLayout/test/ClassroomLayoutTests.cs line 47 at r3 (raw file):

            }

            // room with 3 desks

I think this is a room with 9 desks, unless I am reading this code wrong?

LayoutFunctions/LoungeLayout/test/LoungeLayoutTests.cs line 43 at r3 (raw file):

                var boundaryElements = elements.Where(e => offsetedBox.Contains(e.Transform.Origin)).ToList();
                
                foreach (var contentItem in config.ContentItems)

For future people, maybe it is helpful to add comments inside of the tests like, "check that every piece of expected content exists in a room of a matching size"? This is a general comment for the tests in general, a plaintext explanation of what we are looking for.

foreach (var contentItem in config.ContentItems)
