No need to correct a mistake. I would just propose for the next time to 
put a short comment in case you can for some reason not provide a test 
case. This shows people you did not forget about it, but had a reason 
why it was not possible/useful.

People can then still comment on this reason, but in most cases the 
reason is obvious to most people so we avoid the need for discussions. 
If the reason is not obvious, people may be able to hint on how to 
create a useful test case.
