Hi Moritz,

IMHO there is no general answer, while mostly a separate file seems preferable. 
Writing tests might introduce bugs inside tests, which should not affect the 
source.

OTOH in some cases it might make sense not to use a source until tests passed.
Then making it part of the source seems consequent.

Cheers,

Andreas
