Thank you for the review again!
I have extended the test to upper and bottom cases. However, it seems like we
can not make
the assert fail by simply manipulating the top and bottom padding and margin
values.
I created a reference test by setting the border color to white in cases where
the border
should not be displayed. I tried to set the border style to 'none' or 'hidden'
instead, but
it made the content box shift by a few pixel (the width of the border).
