I will not comment on the "ugly", "repetitive", "error-prone" and 
"wrong" characterizations.  As I wrote in my previous message these are 
not defined objectively.

However, please realize that the whole issue is about something which is 
not functional in the first place!  Under this prism, I am not very 
surprised you cannot, or at least find it difficult to, find a "clean 
functional" solution...  I would even argue that it is better this way. 
(I.e., that there is a "penalty" for wanting to test non-functional 
code.  If you find it disturbing, then simply write functional code.)
